Manota planistylus sp. n. ( Figs 2B , 26 )

Description. Small species.

Male. Head. Antenna with fourth flagellomere 2.1 times as long as wide. Maxillary palpus with third palpomere bearing 3 curved sensilla; fourth palpomere with a parasegment apically.

Thorax. Anterior basalare bare. Laterotergite setose. Episternum 3 with ventral portion setose. Wing. Length 1.4–1.5 mm. Membrane with a few setae along posterior margin. Sc bare. CuA2 fading away proximally.

Terminalia ( Figs 2B , 26 ). Sternite 9 with only the posterior margin distinct; margin situated below mid length of gonocoxites, convex. Ventro­lateral lobes of gonocoxites rounded, marginally each with 1–2 larger setae; interiorly with 1 long seta on a separate rim. Disto­lateral lobes of gonocoxites very short; along posterior margin with some 5 very large, straight setae. Gonocoxites in position I with 1 medium­sized, blunt megaseta; in position II with 3 short, blunt megasetae; in position III with 2 flat, pointed megasetae; with 2 large and 2 smaller setae displaced from position IV to posterior margin of gonocoxites. Gonostyli very large, subrectangular in ventral view; each dorsally on posterior edge with 4(–5) comparatively fine setae, on posterior margin with 1 re­curved seta directed dorsally; dorso­subbasally near anterior margin with 1 seta. Parastylar lobes small, weak, bare (not illustrated). Tegmen almost evenly tapering to tip; ventro­lateral lobes distinct. Hypoproct rounded apically; with long setae laterally.

Diagnostic characters. Among the species with setose laterotergites, it is very similar to M. rectolobata and M. intermedia , all three species having the disto­lateral lobes of the gonocoxites much reduced and the gonostyli very large and flat. For differences, see under the following two species.

Etymology. From Latin, planus, flat, and stylus, style, referring to the outline of the gonostyli.

Types. Holotype. Male, Costa Rica, Puntarenas province, Corcovado National Park, 600 m S Cerro Rincón , 745 m, 23 April–24 June 2002, by Malaise trap, J. Azofeifa ( INBio sample #70842) . Paratypes. 8 males, same data as the holotype .
