( Figs 5-10 ; Tables 3-5 ) TYPE SPECIES. — Comorocolya ngazidja n. sp. , by present designation. DISTRIBUTION. — Indian Ocean, Comoros : Grande Comore , Anjouan , Mohéli . DIAGNOSIS. — This new genus has the unique and striking peculiarity of lacking front coxal process and having distinct mid dorsal subbasal spurs. In addition, Comorocolya n. gen. is characterised by: the prosternum unarmed (within Phisidini , only Paraphisis Karny, 1912 , Meiophisis Jin, 1992 , and Comorophisis n. gen. share this peculiarity); mid trochanter spine present; mid dorsal apical spur present; FW reduced, not reaching hind knees; male epiproct small, semicircular, not specialised; male cerci not cylindrical, specialised; male paraprocts reduced; females tergite VIII with hindward projecting folds on lateral lobes. DESCRIPTION Body size moderate ( 12-17 mm ). Pro: anterior margin weakly concave; lateral lobes shallow; ventral margin rimmed; prosulcus distinct, mesosulcus distinct on lateral lobes. Prosternum unarmed; mesosternal processes forming inconspicuous bulge; metasternum unarmed. Thoracic opening of small to medium size. FW and HW reduced. Fore leg without distinct coxal spine. Tympanal area of T1 FIG. 5. — Comorocolya n. gen. : A , C , E , G , I , male last tergites and cerci, dorsal view (cerci are plane); B , D , F , H , J , male terminalia, ventral view (N.B.: the subgenital plate is plane, not the cerci); A , B , C. ngazidja n. gen., n. sp. , holotype (MNHN-ENSIF2970); C , D , C. ndzuwaniensis n. gen.,n. sp. , holotype (MNHN-ENSIF3003); E , F , C. ndzuwaniensis n. gen.,n. sp. ,paratype (MNHN-ENSIF2998); G , H , C. mwaliensis n. gen., n. sp. , holotype (MNHN-ENSIF2968); I , J , C. mwaliensis n. gen., n. sp. , paratype (MNHN-ENSIF2987). Scale bars: 1 mm. inconspicuously inflated. Mid leg with a distinct trochanter spine.T2 with one dorsal subbasal spur; with dorsal apical spur. Ventral spur formulae: T1 7 (rarely 6)/7 (rarely 6) subapical spurs; F1 6/5 (in one specimen 6/6) spurs;T2 5-6/5-6 (proximal spur often minute) subapical spurs; F2 4/1-2 spurs. F3 with 5-11 ventral spines.T3 with: 9-15/7-10 ventral spines and 17-23/16-20 dorsal spines. Males Wings ( Fig. 7 ): left mirror area circular or D-shaped. Terminalia ( Fig. 5 ): epiproct small, semicircular, not fused with last tergum. Paraprocts very small, hardly visible dorsally, apical end bent forward. Cerci: widened in basal half; curved and narrowed distally.SGP:broad; posterior margin sinuate, almost strait; with minute styli. Phallus without obvious sclerified plates on dorsal phallomeres. Epiphallus ( Fig. 6 ) with single undivided rod, cephalic lobe widened or not (dorsal view); head ventrally with distinct tubercles (side view). Females SGP without emargination or with minute median notch.Tergite VIII with hindward projecting folds on lateral lobes (cf. remark below). O weakly gradually curved upwards with serrated margins apically. Colour No obvious lateral lines on Pro; males left mirror area with dark spot. BIOACOUSTICS Only the song of two out of three species is known ( Fig. 10 ). Echeme-sequences are lasting tens of seconds. Echemes are usually disyllabic and irregularly repeated. Fundamental peaks in ultrasound range between 30-40 kHz. REMARKS As already pointed by Rentz (2001) , the hind and ventral margins of females tergite VIII appear as a valuable often neglected character at both generic and specific levels. In this genus, species are well defined by the male cerci but male epiphallus does not seem a very stable character.
