Manota costaricensis sp. n. ( Fig. 19 )

Description. Small species.

Male. Head. Antenna with fourth flagellomere 1.8 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 bare. Episternum 3 with ventral portion setose. Wing. Length 1.3–1.8 mm. Membrane with a few setae along posterior margin. Sc bare. Junction of CuA2 into CuA1 incomplete.

Terminalia ( Fig. 19 ). Sternite 9 with only posterior margin distinct; margin situated at mid length of gonocoxites, straight or slightly emarginate. Ventro­lateral lobes of gonocoxites each rounded; interiorly with 1 short seta on a separate rim. Disto­lateral lobes of gonocoxites each moderately long; with very large, straight setae directed posteriorly and long, curly setae directed inwards. Gonocoxites in position I with 1 short, blunt megaseta; in position II with some 7 short, stiff setae; in position III with 1 pointed megaseta plus 1 flat, two­branched megaseta with one branch whip­like and the other rounded apically; in position IV with 4 moderately long setae curved inwards. Dorsal margin of gonocoxites with a row of 7–8 setae decreasing in length posteriorly, followed by a stripe of large microtrichia. Gonostyli small, flat; each bilobed, distal lobe with 1 strongly re­curved seta apically plus 1 seta centrally, proximal lobe with some 3 setae each centrally, marginally and apically, with one apical seta clearly enlarged. Parastylar lobes hidden behind gonostyli, small, almost pointed apically (not illustrated). Tegmen tapering almost evenly to tip; ventro­lateral lobes often distinct. Hypoproct rounded apically; with fine, rather 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 rather small and flat. The array of megasetae dorso­interiorly on the gonocoxites is almost identical with that of M. fraterna and M. parva (next species), whereas the setation along the dorsal margin of the gonocoxites is species specific, as is the vestiture of the gonostyli.

Etymology. Derived from Costa Rica, referring to the fact that this species is among the most common and typical Manota species in Costa Rica.
