Striatanus Li & Wang

Type species: Striatanus curvatanus Li & Wang, 1995: 189 Head, pronotum and scutellum nearly black. Forewing yellowish brown, with tinted dapples; veins whitish yellow, distinct. Head and thorax with sparse, short, whitish hair. Head (Figs 1, 2) conically produced, vertex distinctly longer than wide, about as long as pronotum and scutellum together or shorter; lateral margin carinate; median longitudinal carina lamellate; submarginal carina mesad of ocelli on head; area between median carina and submarginal carina distinctly concave. Face (Figs 2, 3) including eyes, much longer than wide; frontoclypeus with median longitudinal carina more strongly elevated in upper half than in lower half, laterally obliquely striate; clypellus broad and swollen at base, narrowed apically, shagreened; lora reaching apex of clypellus, shagreened, flat; gena strongly declivous laterally. Pronotum (Figs 1, 2) broad, wider than head; basal area very slightly carinate medially, lateral margin carinate, hind margin slightly indented medially. Scutellum (Figs 1, 2) triangular, about as long as pronotum, with transverse depression distinct. Forewing (Figs 1, 37) punctate near costal margin, veins prominent; anal vein 1A and 2A fused medially; four apical cells; appendix very narrow ( Fig. 37 ). Hindwing ( Fig. 38 ) venation complete. Hind femoral macrosetae 2+1+1.

Male pygofer (Fig. 4) with ventral process. Subgenital (Fig. 9) plate elongate, macrosetae irregularly distributed, row of hair-like setae submarginally; apex rounded. Style (Fig. 8) somewhat elongate, basal articulating arm very short, anterior lateral arm elongate, apophysis foot-like, with several setae and elongate lateral angle. Connective (Fig. 7) Y-shaped. Aedeagal shaft (Fig. 6) in lateral view curved dorsad, with at least pair of processes anteriorly near middle of aedeagal shaft; gonopore subapical.

Remarks: This genus is similar to Pythamus Melichar , Riseveinus Li , and Vangama Distant in appearance, but they can be distinguished from each other by the length and shape of head, the shape of claval veins of the forwewing, and the presence or absence of a ventral process on the male pygofer. Keys to Strianatus and related genera, and to species of Strianatus are given below.
