M. A. SCHOUTEN & J. P. DUFFELS Institute for Biodiversity and Ecosystem Dynamics (Zoological Museum), University of Amsterdam, The Netherlands A REVISION OF THE CICADAS OF THE PURANA CARMENTE GROUP (HOMOPTERA, CICADIDAE) FROM THE ORIENTAL REGION Schouten, M. A. & J. P. Duffels, 2002. A revision of the cicadas of the Purana carmente group (Homoptera, Cicadidae) from the Oriental region. Tijdschrift voor Entomologie 145: 29-46, figs. 1-20, table 1. [ISSN 0040-7496]. Published 1 June 2002. The Purana carmente group is proposed for a supposedly monophyletic group of seven cicada species from the Oriental region. Two species of this group are redescribed: P. carmente from Java and Sumatra, and P. barbosae from Jolo (Philippines); the latter species is taken out of synonymy with P. carmente. Four species are described here for the first time: P. hermes sp. n. from Sabah and Sarawak, P. infuscata sp. n. from Borneo, P. obducta sp. n. from the Malayan Peninsula, Sabah, and Sarawak, and P. sagittata sp. n. from the Malayan Peninsula. P. dimidia, which was recently described from China and Vietnam, also belongs to this group. A key to identify the males and distribution maps of the species are provided. Correspondence: M. A.

Distant (1905a) erected the genus Purana when he divided Leptopsaltria Stål, 1866 in three genera: Leptopsaltria, Purana, and Maua. In Distant s catalogue (1906) these genera were placed in the division Dundubiaria. In 1923, Moulton transferred Purana and the genera Leptopsaltria, Maua, Nabalua Moulton, 1923, and Tanna Distant, 1905 to the new section Leptopsaltriaria, characterised by the presence of tubercles on the ventral side of the male abdomen. Metcalf (1963) classified the Leptopsaltriaria as a subtribe of the tribe Dundubiini, and added several genera that lack the characteristic tubercles on the male abdomen to that group. In this paper, we follow Moulton s restricted concept of the Leptopsaltriaria. Moulton (1923) distinguished the genera Leptopsaltria, Purana, and Maua, largely upon morphometric characters as relative length and width of head, thorax, and abdomen. In our view it is highly questionable whether these characters can be used to unravel the phylogenetic relationships within the Leptopsaltriaria. The recent recognition of the monophyletic Purana nebulilinea group by Kos and Gogala (2000) was a first step to a classification of Purana and related genera based on phylogenetic reconstruction. Their morphological study of the male genitalia of a number of species of Purana and Maua suggested that the genus Purana is paraphyletic. Kos & Gogala (2000) supposed that Purana ubina Moulton, 1923 and its relatives and Maua quadrituberculata (Signoret, 1847) and its relatives form one monophyletic group. The present paper proposes another supposedly monophyletic group, the Purana carmente group, for seven species: P. carmente (Walker, 1850), P. barbosae (Distant, 1889), and P. dimidia Chou & Lei, 1997, and 4 new species: P. obducta, P. hermes, P. infuscata, and P. sagittata. The species of the group are described and relationships within the group are investigated.

The localities and other label data of the specimens studied for this revision were filed in a FileMaker Pro 4.0 database. The maps of the species distributions were printed from this database using the programme MapInfo for Power Mac, version 4.0.3, on maps of ADC-Worldmap version 2.0 vol. 4 Southern Asia & Australia. Random selections of specimens (or all available specimens) were used for calculating the ranges, averages and standard deviations of the size of the body and body parts mentioned in the descriptions. Measurements were taken using a sliding calliper. PHYLOGENY The Purana carmente group is erected to accommodate P. carmente and its related species. The monophyly of this group is based on three presumed apomorphic characters: (1) male timbal cover with triangular, black marking (2) basal veins of the 2nd and 3rd apical areas of the tegmina not or very weakly infuscated, and (3) male opercula relatively long and slender, reaching or passing the posterior margin of the 3rd abdominal segment. The species centred around Purana tigrina form the most likely sister group of the P. carmente group. Purana tigrina and its relatives are characterised by the prominently infuscated 2nd and 3rd apical areas of tegmina and the elongated, first pair of tubercles. The sister group relationship of the P. carmente group and the P. tigrina group is supported by the following characters: the predominantly black lower part of postclypeus and mandibular plate, and the small first apical cell of the tegmina. A phylogenetic analysis was carried out in order to investigate the relationships within the P. carmente group. Purana tigrina was used as outgroup for this Table 1. Character state matrix for the species of the Purana carmente group and the outgroup used in the cladistic analysis. Numbers refer to the characters as discussed in the text. analysis. The characters used are discussed below and the matrix is given in table 1. 1. Medial margin of male operculum: (0) shaded with black (figs. 6, 9, 13, 14); (1) with broad black band (figs. 3, 12, 19). 2. Male operculum: (0) short, reaching no further than half or two thirds of 3rd abdominal segment; (1) long, reaching beyond two thirds or even beyond posterior margin of 3rd abdominal segment. 3. Basal pygofer lobes: (0) long, only basally connected to lateroventral part of pygofer (figs. 4, 15-17); (1) short, for the greater part connected to pygofer (figs. 7, 10, 20). 4. Uncus: (0) uncus with median lobe, but without lateral lobes (figs. 4, 15, 16, 17, 20); (1) uncus with a median and two lateral lobes (figs. 7, 10). 5. Claspers: (0) absent (figs. 4, 7, 10, 20); (1) present (figs. 15-17). 6. Dark patches on pronotal collar just in front of the anterior ends of the lateral mesonotal fasciae: (0) small, not connected with lateral fasciae of mesonotum; (1) broad, usually connected with lateral fasciae of mesonotum.

(1997), and Kos & Gogala (2000), the genus Purana comprises at least 35 species, which are distributed mainly in Southeast Asia: Myanmar (Burma), Thailand, Cambodia, Vietnam, the Malayan Peninsula, Philippines, and the Greater Sunda Islands, but also occur in India, Sri Lanka, China, Taiwan, and Japan. So far, only two species of Purana have been recorded from east of Wallace s Line: P. celebensis (Breddin, 1901) from Sulawesi and P. carolettae (Esaki, 1936) from the Caroline Islands in the Pacific. 30

SCHOUTEN & DUFFELS: Purana carmente group Fig. 1. Cladogram showing the relationships between the species of the Purana carmente group. Numbers refer to characters discussed in the text. Closed bars are synapomorphies (5* is a reversal), open bars are homoplasies. The Purana carmente group is distributed in Vietnam, the southern part of China, the southern Philippines, the Malayan Peninsula, Borneo, Sumatra, and Java. The cladogram of the group (fig. 1) shows that the carmente group can be subdivided in two monophyletic groups. The first group is distributed in the Greater Sunda Islands and the Malayan Peninsula. It consists of four species: P. carmente from Java (and known from one locality in southern Sumatra), P. infuscata and P. hermes from Borneo and P. sagittata from the Malayan Peninsula, Sumatra, and Borneo. The second group has a more northern distribution. This group consists of P. dimidia from Vietnam and China, P. barbosae from the southern Philippines, and P. obducta from the Malayan Peninsula and Borneo. P. dimidia from the mainland of South East Asia is the sister species of the other two species. TAXONOMY Characterisation of the Purana carmente group The species of the carmente group show a striking similarity in external characters but a great diversity in structure of male genitalia and in shape and coloration of the male operculum. The body is relatively small: body length of males 19.1-24.2 mm, of females 17.0-20.8 mm. Body generally ochraceous to dark brown, sometimes with an olivaceous tinge on parts of head and thorax, especially in fresh specimens; pronotal collar and vertex lobes somewhat lighter. Markings on head and thorax distinct. Lower part of postclypeus and mandibular plate predominantly black and covered with long silver setae and white wax. Each of the lateral ocelli enclosed by a black, triangular marking. Pronotum with two narrow, black central fasciae and variable markings on and along the fissures. Anterior margin of pronotum medially with narrow black band. Posterior margin of pronotal collar shaded with black. Mesonotal markings consisting of five distinct, brown to black fasciae: a median fascia, a pair of paramedian fasciae, and a pair of lateral fasciae. A pair of black dots in front of anterior angles of cruciform elevation. Tegmina hyaline, sometimes slightly bronzed towards apex, basal cell ochraceous; venation ochraceous in basal half, brownish to black in apical part. Dorsal side of abdomen densely covered with fine, short, golden setae. Posterior margins of tergites with narrow black band. All species have a pair of dark tubercles on sternites 3 and 4. Timbal covers with distinct triangular brown to black marking reaching from posterior margin of timbal cover to the anterior. Male opercula narrow, elongate, and wide apart, their apices obtusely angulate, but variable in shape, length and colour. Female opercula short. Male genitalia with a pair of distinct basal pygofer lobes and a median uncus lobe, while some species have a pair of lateral uncus lobes or a pair of claspers. Identification The species of the Purana carmente group mainly differ in characters of the male genitalia and the male operculum. Identification of the females of the carmente group is difficult, since the coloration of and marking on the body are very uniform, while the small variation in these characters shows overlap between the species. Females of the carmente group can be distinguished from females of other Purana groups by the lack of infuscations on the tegmina, except for P. infuscata. The latter species has weakly developed infuscations at the basal veins of the 2nd and 3rd apical areas, and can easily be confused with other species of Purana or even Maua. 31

Purana carmente; Zaidi & Ruslan 1998: 349 (=?P. obducta or P. hermes). Males of Purana carmente can be distinguished from other species in the carmente group by a very broad and triangular uncus and by an operculum that is black for the greater part, pointed outward and reaches to the 4th abdominal segment. P. carmente is quite similar to P. hermes in shape and coloration of the male opercula, though the medial part of the operculum of the latter species is less heavily coloured with black. Specimens collected by J. M. A. van Groenendael are considerably darker than other specimens, probably due to conservation or preparation. Description Head. Ochraceous to tawny. Eyes encircled with black, the black markings tend to narrow or to be interrupted at level of the vertex lobes. Genae just below antennae with a transverse fascia between eyes and postclypeus. Lower half of mandibular plate black. Ventral part of postclypeus with two paramedian series of 3-4 fairly long and 3-4 short, brown to black, transverse streaks. The transverse streaks are medially connected by an brown to black arcuate line that encloses a broad midventral part of the ground colour and continues into the black coloration covering basal one fourth of postclypeus at clypeal suture. Lateral sides of anteclypeus black. Lateral parts of anteclypeus with white pubescence, mandibular plates silvery hirsute. Black-tipped rostrum reaching posterior margin of 2nd abdominal segment. Each of the lateral ocelli enclosed by a distally broadening, and proximally attenuating, triangular black-brown marking, which reaches beyond median ocellus and proximally (almost) reaches anterior margin of pronotum. These triangular markings are more or less broadly connected at median ocellus. A pair of broad, convex Y-shaped figures, with outer arms longer than inner arms, run parallel to lateral margins of the triangular spots, but are not very clear in the holotype. Thorax. Pronotum. Ochraceous to tawny or dark-brown. Pronotal collar somewhat paler than rest of pronotum and mesonotum. Anterolateral corner of pronotum collar rounded with short and blunt lateral tooth; posterolateral corner bent upward. Two narrow black central fasciae reach from anterior margin of pronotum to pronotum collar, dilated at anterior margin and half-moon- to crescent-shaped posteriorly. A pair of, sometimes very light, brownish to black spots between anterior and posterior oblique fissures. The brown or black colour of the posterior oblique fissure continues posteriorly in lateral direction into a narrow dark brown or black line on ambient fissure. Pronotal collar with dark patches just in front of 33

The species is known only from the holotype, which is in fairly poor condition: the body is very dark and most markings are very faint, while some markings, like the lateral fasciae of the mesonotum, are almost completely absent. Description of male Head. Ochraceous to tawny. Genae with dark brown marking at inner margin of eye. Mandibular plates covered with long silvery setae, lower two thirds black. Upper half of postclypeus on both sides with a series of 4-5 pairs of short, transverse, brown to black streaks which are medially connected by an arcuate line that encloses the upper part of a broad midventral part of the ground colour and continues into a black coloration covering basal third of postclypeus at clypeal suture. Anteclypeus pubescent, lateral parts black. Rostrum ochraceous, short, apex black, reaching to halfway abdominal segment 2. Markings surrounding the ocelli as in P. carmente but very weakly developed. Thorax. Pronotum. Markings as in P. carmente, but with crescent-shaped proximal ends of central fasciae connected. Anterolateral corner of pronotal collar with a more distinct and sharper lateral tooth. Mesonotum. Markings partly very faint, probably due to immaturity of the holotype. Anterior half of median fascia narrow, posterior half twice as broad, and broadened at cruciform elevation. Paramedian 37

SCHOUTEN & DUFFELS: Purana carmente group fasciae narrow and more strongly curved inwards than in other species of the carmente group. A pair of round black spots in front of cruciform elevation. Lateral markings faint and about as wide as, or slightly wider than, posterior part of median fascia. Tegmina and wings. As in P. carmente. Legs. As in P. carmente, but proximal spine a little longer, and angle between femur and proximal spine more acute. Operculum (fig. 6). Short, about 1.4 times as long as broad, reaching to halfway abdominal segment 3, apex broadly rounded, situated medial of mid-line of operculum. Lateral margin straight, medial margin almost straight. Basal part of operculum dark brown. Medial and apical margins of operculum shaded with dark brown. Distance between opercula at apices 2.7 times the distance at point of closest approximation. Abdomen. Slender, 1.7 times as long as broad. Dorsal side of abdomen without markings. Lateral half of timbal cover mainly black. Tubercles on segment 4 smaller, more elongate, and more directed outwards than the round, distally directed tubercles on segment 3. Genitalia (fig. 7). Pygofer ochraceous, narrow at base, abruptly broadened in the middle, and narrowing distally. Basal pygofer lobes short, reaching halfway the pygofer length, and broadly connected to anterolateral part of pygofer. Uncus brown to black with a broad median lobe, which has a sutural line from its base to its blunt bicuspidate apex; median lobe fused with pair of somewhat shorter, flattened, fairly broad and rounded, lateral lobes. Lateral processes of pygofer short with recurved, rounded apices, which do not reach beyond anal valves. Measurements in mm. Body length: 22.0; tegmen length: 26.7; head width: 6.5: pronotum width: 7.0. Remarks A male specimen from the northwestern part of Mindanao (Silipon, Buk. Mind. P.I. 24.vi.1932, L. Phillips collector, F. H. Wymore collection), deposited in the CAS collection, resembles the holotype in structure of genitalia and opercula. This specimen differs from the holotype of P. barbosae in the median mesonotal fascia, which is very broad along its whole length. Due to the poor state of the holotype and the lack of sufficient material for comparison this specimen from Mindanao has not been attributed to P. barbosae. Distribution (fig. 11). The holotype is from Jolo (Philippines), a small island east of Sabah. The records of Purana barbosae from Sabah, Borneo by Zaidi et al. (1999) and Zaidi et al. (2000) probably should be ascribed to P. obducta, P. hermes or P. infuscata. Purana obducta sp. n. (figs. 8-11) Type material. Holotype : MALAYSIA / Pahang / J. P. & M. J. Duffels / & M. Y.

This species can be recognised by the male opercula, which cover the first pair of tubercles partly or completely, and are merely shaded with black along their inner apical margins. The male genitalia of the new species are rather similar to P. barbosae, but its lateral uncus lobes are more rounded. 39

In external features P. hermes is very similar to P. carmente, but it can be distinguished from this species by the presence of a pair of claspers in the male genitalia. The average body size of P. hermes is slightly larger than that of other species of the carmente group. Description Head. Ochraceous. Eyes encircled with black. Genae with a broad transverse line between eyes and postclypeus. Lower two thirds of mandibular plate black. Transverse streaks on ventral side of postclypeus as in P. carmente. Lateral sides of anteclypeus and ventral side of postclypeus at clypeal suture black. Anteclypeus pubescent, mandibular plate covered with long silvery setae. Black-tipped rostrum reaching posterior margin of second abdominal segment. Black markings around lateral ocelli as in carmente, sometimes with small ochraceous spots lateral of median ocellus. Y-shaped figures slightly curved outward, strongly broadened anteriorly; medial leg of Y- shaped figure sometimes interrupted. Thorax. Pronotum. Ochraceous, pronotal collar somewhat paler and with a blunt lateral tooth.

Body length : 21.4-23.6 (22.5 ± 0.6), : 18.8-20.1 (19.4); tegmen length : 27.2-31.2 (29.6 ± 1.4), : 27.6-28.0 (27.8); head width : 6.8-7.0 (6.9), : 6.5-6.8 (6.7 ± 0.1); pronotum width : 7.8-8.0 (7.9 ± 0.2), : 7.2-7.5 (7.3). Distribution (fig. 18) This species is recorded from the Bornean states of Malaysia: Sabah and Sarawak. Etymology This new species described above is most closely related to Purana carmente. Since the name carmente was probably derived from Carmentis, the goddess of prophecy, the new species is named after Hermes, son of Carmentis. 41

P. infuscata can be separated from the other species of the carmente group by its slightly infuscated basal veins of the 2nd and 3rd apical areas of the tegmina. The male opercula are short, reach to two thirds of abdominal segment 2, and have a sparse black coloration. This species is similar to P. obducta in colour and markings on head, thorax, and abdomen, but differs in shape and structure of male genitalia and opercula. Description of male Head. Ochraceous, markings distinct. Black markings surrounding the eyes interrupted at level of the vertex lobes. Transverse fascia between eyes and postclypeus interupted or narrowed in the middle. Rostrum short, reaching halfway abdominal segment 2. Black triangular markings around lateral ocelli as in P. carmente and P. obducta, connected with anterior margin of pronotum and enclosing a large ochraceous spot. Y-shaped figures sometimes very broad. Thorax. Pronotum. As in P. obducta, but lateral tooth on pronotal collar blunt rather than pointed, and crescent-shaped posterior ends of central fasciae touching each other. Mesonotum. Markings narrow, as in P. obducta. Median fascia continuing on cruciform elevation. Lateral fascia either continuous from anterior to nearly posterior margin of mesonotum or consisting of a fascia, reaching from anterior margin to two thirds of mesonotum length, and a black spot at posterior margin. Tegmina and wings. Pale hyaline, tegmina very lightly bronzed toward apices; basal veins of 2nd and 3rd apical areas of tegmina weakly infuscated. Venation ochraceous in basal half, brownish to black in apical part. Legs. As in P. obducta. Operculum (fig. 13). Operculum short and triangular, 1.8 times as long as broad (n = 4), reaching to two thirds of abdominal segment 3. Apex sharply pointed, lateral to medial of midline of operculum. Lateral margin straight, medial margin almost straight and with fairly narrow black band. Basal part of operculum ochraceous. Distance between opercula at apices 2.7 times the distance at point of closest approximation (n = 4). Timbal cavities clearly visible from lateroventral view. Abdomen. Broad, as long as head and thorax together (n = 4). Ground colour of dorsal side ochraceous, ventral side light ochraceous. Tubercles castaneous, tubercles on abdominal segment 4 somewhat lighter than those on segment 3. Timbal covers lighter than abdomen, triangular markings small and distinct. Genitalia (fig. 16). Shape of pygofer broadly oval, slightly broadened in the middle. Basal pygofer lobes fairly long and narrow with darkened rounded apex reaching to three fourths of pygofer length; pygofer lobes connected to lateroventral part of pygofer only at base. Median uncus lobe brown to black, broad at its base, rapidly narrowing into a gently inward curving long, tongue-shaped lobe with central fissure and bicuspidate apex. A pair of slender, strongly developed black claspers is attached to basal part of uncus. Apices of claspers point downwards rather than outwards as in P. hermes. Lateral process of the pygofer rounded, short, not reaching beyond anal valve, and darkening towards apex. Measurements in mm (4 ). Body length : 20.2-21.8 (21.2 ± 0.6); tegmen length : 26.8-28.3 (27.3 ± 0.6); head width : 6.5-6.9 (6.7 ± 0.2); pronotum width : 7.1-7.2 (7.1 ± 0.2). Remarks One of the paratypes from Sandakan differs from the other three type specimens in having weakly developed black markings, especially around ocelli and on postclypeus, and in having no markings on the timbal covers at all. However, since this specimen is similar to the other specimens in genitalia, operculum and other characters, we have no doubt about its identity. Distribution (fig. 18). This species is only found in Borneo. Etymology Purana infuscata is the only species within the carmente group with weakly developed infuscations at basal veins of 2nd and 3rd apical areas of tegmina. Purana sagittata sp. n.

P. sagittata can be easily separated from the other species of the P. carmente group by its extremely slender and pointed median uncus lobe. In the other species of the carmente group the uncus lobes are broader and have a more or less bicuspidate apex. Dr Tomi Trilar and Dr Matija Gogala of the Prirodoslovni Muzej Slovenije, Ljubljana describe the song of P. sagittata in this issue (Trilar & Gogala 2002). Description Head. Tawny to ochraceous, fairly dark. Pattern of markings on head quite similar to P. obducta, but Y-shaped figures fairly broad. Apices of triangular markings surrounding ocelli connected to anterior margin of pronotum. Black-tipped rostrum reaching posterior margin of 2nd abdominal segment. Thorax. Pronotum. Tawny to ochraceous, fairly dark. Central fasciae posteriorly ending in two crescent-shaped, juxtaposed markings which are fused in front of pronotal collar. Pronotal collar of fresh specimens with olivaceous spot at lateroproximal corner. Mesonotum. Markings as in P. obducta but paramedian fasciae slightly oblique to almost straight, hardly dilated at anterior margin of mesonotum. Tegmina and wings. As in P. obducta, but more bronzed. Legs. As in P. obducta. Male operculum (fig. 14). Slender, 1.6-2.0 times as long as broad (n=11), not reaching beyond two thirds of the 3rd abdominal segment. Apex angularly rounded, situated medial or lateral of midline of the operculum. Lateral margin almost straight. Medial margin slightly convex towards apex, and with distinct black band from base to apex. Medial half of basal part of operculum black. Opercula of fresh specimens with green tinge. Distance between opercula at apices 2.3-2.6 times the distance at point of closest approximation (n=11). Male abdomen. As in P. obducta, but triangular marking on timbal cover fairly small, not reaching to halfway the length of timbal cover. Tergites covered with a dense silvery to golden pubescence, which is particularly dense on segments 7 and 8, ventral side of the abdomen with scattered long setae. Male genitalia (fig. 17). Pygofer rather small and 44
