( Figs. 12 View FIGURE 10 – 17 , 28–32 View FIGURE 28 – 37 )

Scymnus (Parapullus) alishanensis Pang et Yu, 1993: 230 ; Yu et al., 2000: 168; Pang et al., 2004: 82; Kovář, 2007: 584; Ren et al., 2009: 68.

Diagnosis. This species is similar to S. (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 View FIGURE 10 – 17 ). 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 View FIGURE 28 – 37 ). Area surrounded by the line evenly and sparsely punctured, relatively narrowly smooth along the line.

Male genitalia: Penis stout, with a developed penis capsule ( Fig. 29 View FIGURE 28 – 37 ), apex of penis forming a large hook ( Fig. 30 View FIGURE 28 – 37 ). Tegmen stout, penis guide slightly constricted near middle and converging gradually to a pointed tip in ventral view ( Fig. 32 View FIGURE 28 – 37 ). Parameres relatively broad, oblong, distinctly shorter than penis guide, apex with two groups long and uniform setae ( Fig. 31 View FIGURE 28 – 37 ). Female not examined.
