Boundarus ancinatus sp. nov.

(Figs 7–12, 26–30, 40–43)

Measurements: ɗ: body length: 4.5–5.0; head width (incl. eyes): 1.3–1.5; head length: 0.7–0.9. Ψ: body length: 5.0–6.0; head width (incl. eyes): 1.4–1.6; head length: 0.8–0.9.

Disk of head black. Pronotum black anteriorly. Forewing generally yellowish brown with black patches, claval area black (Figs 7–12).

Male pygofer with macrosetae subapically; subgenital plate slightly shorter than pygofer in lateral view (Figs 26, 30). Aedeagus with atrial processes hook-like in lateral view; apical processes about one third length of shaft (Figs 27–28).

Etymology: The species name refers to the hook-like anterior processes of the aedeagus.

Material examined: HOLOTYPE: ɗ (NKU), China: Sichuan Prov., Baoxing County, 2700m, 27-June- 1963, coll. Zou Huanguang; PARATYPES: 1 ɗ, 2Ψ Ψ (NKU), same data as holotype.

Remarks: This species is similar to B. trimaculatus Li & Wang, but can be distinguished from the latter by the pattern of black patch on the vertex, the shorter apical aedeagal processes, and the hook-like anterior processes near the middle of the aedeagus.
