Striatanus erectus sp. nov.

(Figs 31–42)

Measurements (male): body length: 7.5–7.8 mm; head width (incl. eyes): 1.6–1.8 mm; head length: 1.5–1.6 mm.

Vertex (Figs 31, 32) less elongate, distinctly shorter than pronotum and scutellum together.

Male pygofer (Fig. 34) in lateral view with apex rounded; ventral process (Figs 34, 42) strongly curved dorsad, apical part tapered apically, with apex somewhat truncate. Aedeagus (Fig. 35) strongly posteriorly produced basally; apical half of aedeagal shaft in lateral view nearly straight, gonopore subapical.

Etymology: The name of this species is derived from the nearly straight aedeagal shaft.

Type specimens: Holotype: 3 (IZAS), China: Yunnan Prov., Pingbian, Daweishan, 1500m, 22-June- 1956, coll: Huang Keren.

Remarks: This species resembles Striatanus curvatanus Li & Wang externally, but can be distinguished from the latter by the shape of the ventral process of male pygofer and aedeagus.
