Figs 7 A–D Material studied. Holotype male. NEW CALEDONIA , Rivière Bleue N.P., humid forest, Malaise trap, 26.V– 6.VI.1986 , Bonnet de Larbogne & Chazeau (in MNHN ). Description. Male. Head . Colour fainted in the specimen. Eye bridge 2 facets wide. Face with 13 scattered longer and shorter setae. Clypeus not clearly discernible in specimen. Maxillary palpus with 3 palpomeres; lengths of palpomeres poorly visible in specimen, palpomere 2 shortest; palpomere 1 with 3 setae, with a dorsal patch of sensilla; surface of antennal flagellomeres rough, flagellomere 4 ( Fig. 7 A) 1.8x as long as wide, the neck about as long as broad, the longest setae shorter than the width of flagellomere. Thorax . Fainted. Anterior pronotum with 2 setae. Episternum 1 with 3 setae. Scutum with long dorsocentrals, with some longer and shorter laterals, scutellum with 2 longer and some short setae. Wing. Hyalinous. Length 1.8 mm . Width/length 0.45. Veins distinct. R1/R 1.0. c/ w 0.70 . r-m and bM subequal in length. M and CuA setose, r-m with 1 seta, bM non-setose. Legs . Apical part of front tibia as in Fig. 7 B: tibial organ with pale vestiture forming a long curved row. Front tibial spur slightly longer than the tibial width. Claws with fine teeth. Abdomen . Setae pale and long. Hypopygium, Figs 7 C, D. Gonocoxa longer than gonostylus, mesial margin with sparse setosity. Gonostylus slightly curved, tumid, with the mesial side weakly impressed; with rather dense apical vestiture, with a slender apical tooth, with 5 megasetae in subapical group, megasetae straight and with distinct basal bodies; without one apical megaseta. Tegmen conical, weakly sclerotized, aedeagal apodeme moderately long. Discussion. Ctenosciara inflata and C. obesa resemble the New Zealand C. ovalis (Edwards) and differ from all other known species of the genus by their broad gonostylus. C. inflata is similar to C. ovalis by having an apically roundish tegmen (truncate in C. obesa ), but differs from both other species in having a megaseta on the lateral side of the apical tooth of the gonostylus. Ctenosciara obesa and C. ovalis lack the apical megaseta, but can be distinguished from each other by the former having a higher number of gonostylar megasetae (9 vs. 7), a stronger apical tooth of the gonostylus, a truncate tegmen and longer setae at the ventromesial margin on gonocoxa ( Figs 7 C and D and Fig. 9 in Mohrig & Jaschhof 1999 ). Etymology. The name is Latin, inflata , inflated, referring to the inflated gonostylus.
