sp. nov.
(A) head; (B) base of antenna: scape, pedicel and three basal flagellomeres; (C) palpus; (D) wing; (E) male terminalia, dorsal; (F) male terminália, dorsal: hypandrium plate-like; (G) male terminalia, ventral: epandrium, cerci and hypoproct; (H) cercus. (Abbreviations: ae = aedeagus, ep = external paramere, ip = internal paramere).
Diagnosis.
Head without cornicula; eyes separated by 2.0 facet diameters; scape without internal protuberance; interocular suture inverted V-shaped; hypandrium with microtrichia arranged in circular groups; aedeagus symmetrical, bifid, digitiform with a medial external lobe; two pairs of parameres, external pair fused medially forming a U-shaped plate; internal pair well sclerotized, lanceolate.
Description.
Male
holotype
. Head without corniculum. Vertex dorsally expanded. Eyes separated by 2.0 facet diameters; eye bridge with four facet rows; interocular suture inverted V-shaped; frons with hair patch not divided at center, extending dorsally and reaching the interocular suture (
Fig. 1A
). Scape subspherical, approximately the same length as pedicel, without internal protuberances. Antenna incomplete; first three flagellomeres fusiform, each one with pair of filiform ascoids (
Fig. 1B
). Relative palpomere proportion: 1.0:1.1:1.2:2.0 (
Fig. 1C
). Wing (
Fig. 1D
). 2.5 times longer than wide; wing membrane brownish, with costal cell darker; lighter spots between veins R

ending at wing tip; CuA not reaching wing margin. Male terminalia: hypandrium plate-like, subtriangular with microtrichia arranged in circular groups (
Figs. 1E, 1F
); length of gonocoxite 0.3 times the length of gonostylus; gonostyli narrow, basally inflated, bare, except in the base with patch of alveoli; aedeagus symmetrical, bifid, distally digitiform; two pairs of parameres, external pair fused forming a U-shaped plate; internal pair ending at the same place of aedeagus, well sclerotized, lanciform, ending in pointed apex; ejaculatory apodeme dorsoventrally flattened (
Fig. 1E
); epandrium 2.5 times wider than long, with two foramina and two distal patches of alveoli (
Fig. 1G
); cercus digitiform, 1.2 the length of epandrium; left cercus with 12 tenacula (
Fig. 1F
) and right cercus with 11 tenacula; hypoproct and epiproct subtriangular with apical micropilosity (
Fig. 1G
).
Female: Unknown
