Manota acutistylus sp. n. ( Fig. 24 )

Description. Small species.

Male. Head. Antenna with fourth flagellomere 1.6 times as long as wide. Maxillary palpus with third palpomere bearing 3–4 curved sensilla; fourth palpomere with a parasegment apically.

Thorax. Anterior basalare and laterotergite each bare. Episternum 3 with ventral portion setose. Wing. Length 1.5 mm. Membrane with a few setae along posterior margin. Sc bare. Junction of CuA2 into CuA1 incomplete.

Terminalia ( Fig. 24 ). Sternite 9 with only posterior margin distinct; margin situated at mid length of gonocoxites, slightly convex medially. Ventro­lateral lobes of gonocoxites rounded, each marginally with 2–3 larger setae; interiorly with 1 seta on a separate rim. Disto­lateral lobes of gonocoxites comparatively short; with large setae directed posteriorly. Gonocoxites in position I with 1 medium­sized, blunt megaseta; in position II with 2– 3 short, blunt megasetae; in position III with 1 pointed megaseta and 1 flat, two­branched megaseta with one branch broadly rounded and the other whip­like; in position IV with 4 large setae; on dorso­posterior gonocoxal margin with an irregular comb of numerous setae directed inwards. Gonostyli small, elongate, pointed apically; each on posterior margin with 1 long, stiff seta directed inwards, 1 long seta directed dorsally, and 1 strong, recurved seta directed dorsally; on anterior margin with 1 seta subbasally. Parastylar lobes moderately sized, weak, bare (not illustrated). Tegmen evenly tapering to tip. Hypoproct tapering to tip; with long setae laterally.

Diagnostic characters. It is in the group of species with both anterior basalare and laterotergites bare; terminalia with sternite 9 barely discernible; the disto­lateral lobes of the gonocoxites large; and the gonostyli small and flat. The array of megasetae dorsally on the gonocoxites is species specific, as are the pointed, apically bare gonostyli.

Etymology. From Latin, acutus, acute, and stylus, style, referring to the outline of the gonostyli.
