Manota parva sp. n. ( Figs 2A , 21 )

Description. Small species.

Male. Head. Antenna with fourth flagellomere 2.0 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 1.4–1.7 mm. Membrane with a few setae along posterior margin. Sc bare. Junction of CuA2 into CuA1 incomplete.

Terminalia ( Figs 2A , 21 ). Sternite 9 with only posterior margin distinct; margin situated at mid length of gonocoxites, straight or slightly convex medially. Ventro­lateral lobes of gonocoxites each rounded; with a rather short interior seta marginally. Disto­lateral lobes of gonocoxites each moderately long; with very large, straight setae directed posteriorly and shorter, straight setae directed inwards. Gonocoxites in position I with 1 moderately long megaseta, pointed in some specimens, blunt in others; in position II with some 7 short, stiff setae; in position III with 1 pointed megaseta plus 1 flat, two­branched megas­ eta with one branch whip­like and the other rounded apically; in position IV with 2–3, rarely 4 moderately long setae curved inwards. Dorsal margin of gonocoxites with a row of some 10 setae slightly decreasing in length posteriorly. Gonostyli reduced in size, flat; each bilobed, distal lobe with 1 strongly re­curved seta apically, proximal lobe with 1 megaseta plus 1 seta apically, and 2–3 setae marginally. Parastylar lobes not discernible. Tegmen almost evenly tapering to tip. Hypoproct rounded apically, each disto­laterally with large setae on small lobes, laterally with fine, rather long setae.

Diagnostic characters. Very similar to M. costaricensis and M. fraterna . The setation along the dorsal margin of the gonocoxites is species specific, as is the vestiture of the gonostyli.

Etymology. From Latin, parvus, small, referring to the small size and inconspicuous morphology of this species.
