Diagnosis. Sclerotized arch on anterior margin of aedeagal sheath with posterior postgonite laterally on each side; anterior postgonites articulated to tips of arch and oriented inward; left, anterior postgonite longer, apically with small claw, and right one shorter, subapically with large hook (“Figs 14, 15” in Gong et al . 2018 ). Supplementary description. Supracervical setae 18–19. Dorsomedial, tentorial apodeme slightly longer than 1/2 basal, parallel portion of dorsolateral, tentorial apodeme. Arista with arb = 3/0; longest, dorsal branch longer than longest seta on pedicel; apical, leaf-like expansion narrower than long, apically tapering and with short, awnlike projection. Palpus with hollow-shaped sense organ (ch.9-2). Cibarial, medial sensilla 9–10 per side; posterior sensilla 5–7 per side. All tarsi entirely yellow. Abdominal sternites III and IV wider than long (ch.22,24-1), with dense setulae on medial surface (ch.26,27-1); III not wider than IV (ch.23-0); V without dense setulae on medial surface (ch.28-0). Setae on and/or near ventral margin of epandrium not denser than those on other portions (ch.32- 0). Surstylus with peg-like teeth (ch.37-0). Hypandrium symmetric (ch.40-0).
