Antenna: Scape with several fine setulae; pedicel with setulae and two larger setae; basal flagellomere short, apex not reaching oral margin, setulae very light, of moderate length (longest at apex of flagellomere); arista with 1 ventral, 7 dorsal branches, plus small terminal fork. Eye slightly egg shaped in lateral view, posterior margin slightly flattened; interfacetal setulae short, dense. Face of moderate height and depth, oral margin slightly concave; carina relatively well developed, narrow (ca. 0.8× greatest width of basal flagellomere), edge slightly flattened, length approximately 0.75× the face depth. One pair vibrissae; subvibrissal setulae very small; cheek of moderate depth; palp with single large, subapical seta. Frons: Sclerites best distinguished in anterior view of head; fronto-orbital plates narrow, shiny; frontal vitta narrow, minutely striate; ocellar triangle seemingly long and narrow, anterior corner reaching to slightly past level of proclinates. Frontoorbital setae: proclinate slightly shorter than posterior reclinate; anterior reclinate small, ca. 0.3× length of posterior reclinate; posterior reclinate slightly closer to proclinate than to inner vertical; ipsilateral proclinate, posterior reclinate and inner vertical setae in line, anterior reclinate slightly lateral to this tangent. Ocellar seta not reaching to proclinate; postocellar setae ca. 0.65× length of ocellar, crossed at tips. Vertical setae long, equal length; inner verticals upright, inclinate; outer verticals lateroclinate, pointed slightly posteriad.

Epandrium arched, with microtrichia on dorsal half only; dorsolateral row of 56 setae, ventral lobe with group ca. 14 setae; lobe thick, short, not reaching to ventral margin of surstylus. Subepandrial lobe wide and short. Cercus not connected to epandrium; entirely microtrichose and setose; ventral margin with fine setulae on mesal corner. Surstylus pendulous, simple, with dorsolateral row 8 peg prensisetae, ca. 12 spiniform prensisetae more medially. Hypandrium well developed, relatively long, almost reaching to apex of aedeagal apodeme; posterolateral lobes turned inward, not wrinkled; paraphysis short, broadly and shallowly protruding, with microtrichia on mesal surface, large seta near middle. Aedeagus slightly longer than aedeagal apodeme, straight in lateral view; with lateral pair of large, forward-pointing, hooklike lobes; aedeagus with few, sparse scales toward apex.
