Abstract Lebinthus crickets from Indonesia and the Solomon Islands are analysed. Six new species are described: L. ambonensis n. sp., L. buruensis n. sp., L. cyclopus n. sp., L. greensladei n. sp., L. kolombara n. sp. and L. villemantae n. sp., and one is redescribed (L. truncatipennis Chopard, 1929). Descriptions focus on male and female genitalia and forewing venation. Data are provided for L. villemantae n. sp. fine scaled habitat, behaviour and song repertoire. Key words: Orthoptera, Eneopterinae, Lebinthini, Lebinthus, new species, Indonesia, Solomon Islands Introduction The cricket subfamily Eneopterinae Saussure, 1874 (Grylloidea) is particularly diversified in the Pacific region and in SouthEast Asia (DesutterGrandcolas & Robillard 2006, Otte 2007), where they are represented by two tribes, the Nisitrini Robillard, 2004, and mostly by the Lebinthini Robillard, 2004 (Robillard & DesutterGrandcolas 2004a, 2006, 2008). The Lebinthini are responsible for an important part of the acoustic diversity of Eneopterinae, with originalities laying mainly in the spectral properties of their songs and the use of high frequencies for communication (Robillard & DesutterGrandcolas 2004b; Robillard et al. 2007; Robillard 2009). In this study six new species of Lebinthus are described from different islands of Indonesia and the Solomon Islands and one species is redescribed. Descriptions focus on male and female genitalia, and forewing venation. Although other species of the genus are known for their dense populations (Robillard 2009), most of the present descriptions are based on few specimens only from several museum collections, without information about species habitat, life history and behaviour. However, based on recent fieldwork in South Sulawesi, more data could be obtained for L. villemantae n. sp. about the species finescale habitat, behaviour, and song repertoire. Material and methods Material. Fieldwork was made in several localities in Sulawesi Selatan, Indonesia. Specimens were collected by sight only, by night and day, in order to observe their habitat and type of activity. Newly collected specimens are deposited in the collections of the Museum Zoologicum Bogoriense, Bogor (MZB) and of the Muséum national d Histoire naturelle, Paris (MNHN). For museum specimens, political districts and islands are mentioned for every specimen within lists of material, and square brackets are used for additional information not mentioned on specimen labels. Male tegminal venation. Male tegminal veins and cells (Fig. 1) are named after DesutterGrandcolas (2003) for Ensifera, and Robillard & DesutterGrandcolas (2004a) for the subfamily Eneopterinae more specifically.

2 Male and female genitalia. Male and female genitalia have been dissected in softened specimens by cutting the membranes between the paraprocts and the subgenital plate, or between the ovipositor and the subgenital plate respectively; they have been observed after cleaning with cold KOH using a binocular microscope Leica MZ16 at magnifications up to 160, and then kept in glycerine in vials pinned under specimens. Male genitalia are named according to Desutter (1987), modified in DesutterGrandcolas (2003) and Robillard & DesutterGrandcolas (2004a). Dotted parts in figures correspond to membranous areas. Abbreviations: see below. Acoustic data. The basic cricket song terminology follows Ragge & Reynolds (1998). One song unit is called a syllable and corresponds to one openingclosure cycle of the male forewings; a repeated group of syllables is called an echeme and corresponds to the calling unit of a species; a series of echemes constitutes an echemesequence. The species Lebinthus villemantae n. sp. has been studied in the field and subsequently in the laboratory. The recordings were made with a modified Condenser Microphone Capsule CM16 (Avisoft Bioacoustics, Berlin), with a flat frequency response from 3 to 150 khz (R. Specht pers. comm.), connected to a TASCAM HDP2 digital recorder (96 khz sampling frequency, 16 bit). Acoustic analyses were performed using the computer software AvisoftSASLab Pro version 4.40 (Specht 2008). Song features were measured using the automatic commands under AvisoftSASLab Pro. Mean values and standard deviation per individual and per species were calculated after adjustment for a common recording temperature of 20 C. All recording files have been deposited in the Sound Library of the Muséum national d Histoire naturelle, Paris. Abbreviations. Descriptions.

Among Lebinthini genera, Lebinthus is more closely related to Agnotecous Saussure, 1878, to which it resembles by microptery and FW venation. It is characterised by its rather smaller size, microptery in both sexes (FW short and hind wings absent), and male FW venation with mirror almost not differentiated from apical field, dorsal field as long or longer than lateral field (it is shorter in Agnotecous), median fold short, triangular and located on dorsum.

It is found in dense populations in wet leaf litter, generally on or under large dead leaves. Behaviour. Only 3 adult specimens were observed in the field, by day in leaf litter in Malawa region, South Sulawesi. Singing activity was recorded in laboratory mostly during night period, but sexual activity seems to occur during both day and night. Mating behaviour has been observed in laboratory; multiple copulations have been recorded and will be described in a forthcoming paper (Robillard et al. in prep.). FIGURE 12.

22 FIGURE 13. Calling song of Lebinthus villemantae n. sp.: A, oscillogram showing 3 successive echemes; B, spectrogram (relative amplitude); C, detailed oscillogram of an echeme; D, detailed oscillogram of a syllable; E, detailed sonogram of an echeme. Symbols: f1 f4, first (fundamental) to fourth harmonic frequencies. Calling song (Fig. 13; Table 2): Five males recorded in laboratory at C are analysed here. The calling song consists of a succession of short echemes of 1.8 ± 0.1 s emitted every 47.1 ± 19 s, with a duty cycle of 3.8%. At 20 C each echeme is made of 99.5 ± 10.6 syllables, with the following characteristics: syllable rate = 58.7 ± 3.8 /s; syllable duration = 7.2 ± 1.9 ms; syllable period = 17.5 ± 4.1 ms; syllable duty cycle = 41.1%; the dominant frequency is 20.1 ± 2.3 khz and corresponds to the fundamental frequency of the song. Courtship song: Less intense and shorter than calling song. Aggressive song: Not observed despite many observations of male interactions. This song is probably absent from the species repertoire. 46 Zootaxa Magnolia Press ROBILLARD
