Diagnosis. The male is unique among the subgenus Chaetalictus in having numerous short, erect bristles in several rows on the posterior margin of S4 (other species either without bristles or if present, in a single row only) and dense bands of long and distinctly branched hairs on the apical parts of S2 and S3 (Fig. 6 f) (other species either without apical hair bands or if present, much narrower and hairs only microscopically branched).
Description. Female. Unknown.
Male. Bl = 5.9–6.1 mm. General habitus (Fig. 6 a). Head. L = 1.6–1.7 mm; W = 1.8–1.9 mm. Head wider than long (Fig. 6 b). Integument black except mandible partly dark reddish-brown. Clypeus, supraclypeal area, paraocular area and vertex sparsely covered with erect, whitish to dark brownish, erect hairs. Mandible simple. Antenna blackish-brown. Flagellomeres of normal structure, slightly thickened medially. A2 slightly longer than A1. Mesosoma. L = 2.2–2.4 mm; ITS = 1.4–1.5 mm. Integument black. Mesoscutum medially shiny, superficially sculptured, without punctures; laterally sculpture stronger, mesoscutum dull (Fig. 6 c). Scutellum as illustrated in Fig. 6 d. Mesoscutum, scutellum, metanotum, mesepisternum and propodeum with greyish to dark brownish, erect hairs. Basal area of propodeum as illustrated in Fig. 6 d; propodeum moderately shiny; surface rugose and impunctate. Marginal region of posterior truncation less sculptured and dull. Wings. Brownish fuscous. Legs. Integument brownish. Vestiture whitish to brownish. Metasoma. L = 2.5–2.7 mm; W = 1.8–1.9 mm. Integument dark brownish-black, margins of metasomal terga narrowly brownish and a little translucent (Fig. 6 e). Apical plate broadly rounded apically. Posterior margin of S4 with numerous short erect bristles in several rows; apical parts of S2 and S3 with dense bands of long, erect and distinctly branched hairs (Fig. 6 f).
