(
Figs. 17A–G
)
Diagnosis.
Apex of Sc unsclerotized; arm of gonocoxite with apical bristles and projections keel-shaped in the posterior margin; three pairs of projections in the aedeagal complex; the inner fused apically, the lateral, slightly thicker; the third pair is half the length than the other two; ejaculatory apodeme long, the same length as the pair of projections in the aedeagal complex parallel to aedeagus.

sp. nov.
A. Scape, pedicel and basal flagellomeres; B. Flagellomeres with ascoids C. Last flagellomeres; D. Palpus; E. Right wing; F. Cerci, epandrium and hypropoct; G. Male terminalia, dorsal; H. Male terminalia, lateral; I. Arm of gonocoxite. (abbreviations: aed = aedeagus, agx= arm of gonocoxite, ap= apiculus, as= ascoid, cerc= cercus, CuA= cubital anal, ej apod = ejaculatory apodeme, epand= epandrium, es= scape, fl=flagellomere; gst = gonostylus, hyprct = hypoproct, M= medial, pd= pedicel, pac = projections in the aedeagal complex, R= radial, Sc= subcosta, sg1= first segment of palpus; sg2= second segment of palpus; sg3= third segment of palpus).
Description. Male.
Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape subcylindrical, pedicel subspherical; flagellomeres pyriform; ascoids 1.4 times as long as the length of flagellomere (
Fig. 17A
). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.7:0.6 (
Fig. 17B
). Wing. apex of Sc unsclerotized; sc-r unsclerotized; R4+5 incomplete at base; M2 with base unsclerotized; M3 not reaching CuA1, r-m and m-cu absent (
Fig. 17D
). Male terminalia: Hypandrium and gonocoxites fused. Posterior arm of gonocoxite with apical bristles, the basal 2.5 times longer than the apical; in the 1/4 apical with projections keel-shaped in the posterior margin (
Figs.17E, 17F
). Gonostylus not visualized. Aedeagal complex with three pairs of projections; the inner fused apically, slender and tapered, almost the same length as the gonocoxite; the lateral, slightly thicker and the same length as the medial; the third pair is half the length than the other two, two times wider than the lateral and ends on a small pointed expansion. Aedeagus with a single opening reaching half the length of the largest projections in the aedeagal complex (
Fig. 17F
). Ejaculatory apodeme as long as the pair of projections in the aedeagal complex parallel to aedeagus. Epandrium subcircular; cercus digitiform, with a row of setae in an expansion on the ventral surface of the apex, about fourteen (
Fig. 17C
). Hypoproct tapering apically with apical micropilosity (
Fig. 17G
).
