1 FOLIA HEYROVSKYANA Vol. 6(4): ,1998 ISSN editum: December 31,1998 Studies in the Philippine Coraebina (Coleoptera: Buprestidae) Part V: a new genus for Polyonychus fisheri and three new species of Cisseicoraebus Charles L. Bellamy Coleoptera Department, Transvaal Museum, P.O.Box 413, Pretoria 0001, SOUTH AFRICA, bellamy@tm.up.ac.za Abstract. A new genus, Philippscelus gen. n., is erected and a lectotype designated for Polyonychus fisheri Hoscheck, Three new species of Cisseicoraebus Kerremans, 1903 are described from the respective Philippine Islands: C. violaceus sp. n. from Negros, C. subgrandis sp. n. from Mindanao and C. boudanti sp. n. from Dinagat. A key to the Philippine species of Cisseicoraebus is given. Dorsal habitus and male genitalia illustrations are provided. Taxonomy, new genus, new species, Coleoptera, Buprestidae, Coraebina, Palaearctic region Introduction The fauna of the buprestid subtribe Coraebina from the Philippine archipelago is slowly becoming better understood. Four recent efforts have focused on this fauna (Bellamy 1990a, 1990b, 1991a, 1991b) but several groups and taxa remain poorly understood. With the threats to indigenous habitats on most of the large islands, new taxa that are presented for study need to be named to increase our understanding of the unique biodiversity of this interesting part of the world. The specimens discussed in this paper are from the following collections: KACJ NMPC NSMT ZMHB K. Akiyama collection, Kanazawaku, Yokohama, Japan. National Museum, Prague, Czech Republic, S. Bflf curator. National Science Museum, Tokyo, Japan. Zoologisches Museum, Humboldt Universitat, Berlin, Germany, M. Uhlig curator. Philippscelis gen. nov. T y p e s p e c i e s. Polyonychusfisheri (present designation). Elongate, subcylindrical, flattened above and below; integument strong striolaterugose; entire surface virtually glabrose except short, sparse, adpressed, fine setae for lateral portions of abdominal sterna, and most of surface of sternum 5.

2 116 Studies in the Philippine Coraebina (Coleoptera: Buprestidae) Part V Head. Frontovertex very feebly depressed between eyes; eyes of moderate size, inner margins feebly diverging dorsally; frontoclypeus strongly compressed between antenna1 insertions; distal margin arcuately excavated. Antennae serrate from antennomere five. Pronotum. Wider than long, widest at basal 113; disc entire, only slightly convex medially; anterior margin arcuate; basal margin bisinuate; basolateral angle obtuse; lateral margin arcuately emarginate in basal 113 to angulate projection, then narrowing slightly to before anterior 113 and then gently arcuately convex to anterior margin. Elytra. Disc entire, evenly transverse; slight basal depression between humerus and scutelum; posterolateral margin serrulate; apical angles separately rounded; epipleuron short, ventrally deflexed, extending only to opposite mesepimeron. Pygidium. Distally feebly bilobed. Thoracic sterna. Prosterum with moderately produced, bilobed mentonniere; process subparallel; mesepimeron partially visible beyond basal abdominal projection; metacoxal plate with anterior margin strongly sinuate. Abdominal sterna. Suture between sterna 1 and 2 only indicated laterally; distal margin of sternum 5 angularly emarginate, entire margin finely dentate. Legs. Femora fusiforrn; pro- and mesotibiae feebly arcuate; metatibia straight, with small rounded tooth on external face at about basal 113, setal comb present on external face from before basal 113, extending to beyond distal 113; tarsomeres 1-4 each slightly shorter than preceding, each with ventral pulvillus; 5 elongate, length equal to 2+3+4, claws bifid. Genitalia. 8 (fig. 5) short, completely sclerotized, sensory setae on lateroapical portion of parameres; Q of general coraebine type, short, with paired ventral setal brushes. E t y m o 1 o g y. The new generic name is a combination of the roots of the names: Philipp for Philippine Islands and scelis to highlight the presumed, albeit distant, relationship with Toxoscelus Deyrolle, 1864 and Neotoxoscelus Fisher, R e m ark s. This new genus is very distinct from all Philippine coraebine genera as indicated in the generic key presented earlier (Bellamy 1990a). The surface sculpture, the emargination of the posterolateral pronotal angle and the arcuate pro- and mesotibiae suggest a relationship within the generic complex that contains Cryptodactylus Deyrolle, 1864, Cupriscobina Bellamy & Holm, 1985, Kerremansia Peringuey, 1908, Neotoxoscelus Fisher, 192 1, Strigula Kerremans, 1893 and Toxoscelus Deyrolle, This is obviously an older lineage within the subtribe as indicated by its broad distribution throughout the Ethiopian and Oriental regions.

Hoscheck (193 1) listed a range of size at the time he described this species, and indicated that he saw six specimens. Four of these were listed from the Zoologisches Museum, Berlin and have been examined. The other two specimens have not been located but are presumed to be part of the G. Frey collection, which had been removed from the Zoologische Staatssarnmlung, Miinchen, just prior to my visit in October of 1995; these two specimens will be labelled as paralectotypes should they ever become available for study. Obenberger's (1934) placement of P. fisheri in Neotoxoscelus suggests a slightly better understanding by him than that indicated by the original combination of the species in Polyonychus Chevrolat, 1837 by Hoscheck.

The Philippine componeilt of the Cisseicoraebus was revised by Bellamy ( b) and was more recently discussed by Kubafi (1 996). The three new species described below are all substantially different from those previously known while each is, unfortunately, known only from the holotype. Cisseicoraebus violaceus sp. n.

This species is named for Jean-Louis Boudant, a French relief worker and purveyor of Philippine insect specimens. It was Mr. Boudant who provided the access of this specimen and who has graciously agreed to allow the retention of the holotype in the collections of NMPC. D i f f e r e n t i a 1 d i a g n o s i s. This new species belongs to the group of species consisting of C. cisseoides, C. piperi and C. bicoloratus. These four species share a generally more robust body form as well as having the dorsal vestiture concentrated laterally on the pronotum. Cisseicoraebus boudanti sp. n. is the most easily recognized of these species with the blue reflection of the elytra and the bright red orange setae of both the dorsal and ventral surfaces.
