Diagnosis.
This species is similar to

P
.)
tsugae
in general appearance and male genitalia, but can be distinguished from it by the dilated of the pre-apex of penis. The shape of the parameres and penis guide is diagnostic.
Description.
TL:
2.40 mm
, TW:
1.65 mm
, TH:
1.10 mm
, TL/TW: 1.45, PL/PW: 0.48, EL/EW: 1.12.
Body oval, moderately convex, dorsum surface with fine, pale yellowish pubescence (
Fig. 12
). Head and antennae yellowish brown. Pronotum, scutellum and elytra reddish brown. Underside yellowish brown except metaventrite reddish brown.
Head small, 0.65× of pronotal width (HW/PW=0.75/1.15). Punctures on head finer than eye facets, separated by 1–2 diameters, with white pubescence. Eyes small, the widest interocular distance 0.47× of head width. Pronotum 0.70× of elytral width (PW/EW=1.15/1.65), pronotal punctures larger than those on head, 1–1.5 diameters apart. Surface of elytra with densely punctures, separated by 1–2.5 diameters. Prosternal carinae extending to anterior margin, slightly convergent anteriorly. Prosternal process trapezoid, length 5.0 times of width at the base. Abdominal postcoxal lines incomplete, slightly recurved toward the base of ventrite (
Fig. 28
). Area surrounded by the line evenly and sparsely punctured, relatively narrowly smooth along the line.
