Male. Vertex approximately 0.25 of head width; gena 0.25–0.27 of eye height; parafacial 1.2–1.4 times as wide as width of first flagellomere; first flagellomere 3.3–3.5 times as long as wide and 2.5–3 times as long as pedicel; apical one-quarter to one-fifth of palpus light orange to reddish yellow; sides of third and anterolateral portions of fourth abdominal tergum reddish yellow; third to fifth terga with dense greyish yellow pruinosity on anterior half; third and fourth abdominal terga each often with a pair of short discal setae. Male postabdomen: surstylus curved ventrally at middle in lateral view; cerci tapered to apex in lateral view with many long golden setae on basal three-quarters, apex slightly curved ventrally, nearly oval in dorsal view; pregonite nearly straight with some setae dorsally; postgonite rather narrow and curved ventrally; epiphallus club-shaped; distiphallus nearly triangular with a small membranous area dorsocentrally.

Body length. 11–13 mm.

Female. Unknown.

Holotype

Male ( ITBC), Inobong , Sabah, Malaysia, 2 February 2006, T. Tachi. Paratypes

The name of this species is based on Sabah, the Malaysian state containing the type locality .

Distribution

Malaysia (Sabah).

Host

Unknown.
