Manota corcovado sp. n. ( Fig. 16 )

Description. Small species.

Male. Head. Antenna with fourth flagellomere 2 times as long as wide. Maxillary palpus with third palpomere bearing 3 curved sensilla; fourth palpomere with a parasegment apically.

Thorax. Anterior basalare and laterotergite each bare. Episternum 3 with ventral portion setose. Wing. Length 1.6 mm. Membrane with a few setae along posterior margin. Sc bare. CuA2 fading away proximally.

Terminalia ( Fig. 16 ). Sternite 9 with only a short portion of posterior margin distinct, i.e. two small lobes; margin situated beyond mid length of gonocoxites. Ventro­lateral lobes of gonocoxites densely setose; each lobe interiorly with 1 short seta on a separate rim and, more anteriorly, with an ovoid lobe bearing large microtrichia. Disto­lateral lobes of gonocoxites moderately long; each with very large setae directed posteriorly. Gonocoxites in position I with 1 moderately long, blunt megaseta; in position II with 3 short, blunt megasetae; in position III with 2 flat megasetae, each two­branched with one branch pointed, or bi­pointed, and the other branch rounded apically; in position IV with 3 twopointed megasetae; between positions III and IV with a slender lobe bearing 6–7 setae; dorsal gonocoxal margin unmodified. Gonostyli small, flat; each posteriorly with 1 strongly re­curved, blunt seta, anteriorly with 1 large plus 2 smaller setae apically. Parastylar lobes hidden behind gonostyli, each lobe with ventral portion stout and bare, and dorsal portion with a marginal comb of some 15 trichia (not illustrated). Tegmen tapering almost evenly to tip. Hypoproct rounded or blunt apically; with fine, short setulae laterally.

Diagnostic characters. Among the species with both anterior basalare and laterotergites bare, and terminalia with sternite 9 barely discernible, it has the disto­lateral lobes of the gonocoxites large, and the gonostyli small and flat. The array of megasetae dorsally on the gonocoxites is species specific, even though very similar to M. diversiseta . (See next species).

Etymology. From the type locality, Corcovado [National Park], which proved to be extremely rich in Manota species.

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 #70842 ) . Paratypes. 8 males, same data as the holotype ; 1 male, same data , but 800 m S Cerro Rincón ( INBio sample #70843) .

Other material studied. 1 male, same National Park as types, but Cerro Rincón , La Tigrilla , 7 Feb.–23 April 2002, J. Azofeifa ( INBio sample #70848); 1 male, same National Park , but Cerro Mueller, 20 Dec. 2001 – 7 Feb. 2002, J. Azofeifa ( INBio sample #67160) .
