Scymnus (Parapullus) tsugae Yu et Yao, 2000: 168 ; Pang et al., 2004: 82; Kovář, 2007: 584.

Diagnosis. This species closely resembles S. (P.) alishanensis in general appearance, but can be distinguished from it by the penis. The tegmens are also diagnostic.

Description. TL: 2.40–2.48 mm, TW: 1.35–1.43 mm, TH: 1.05–1.10 mm, TL/TW: 1.73–1.78, PL/PW: 0.48– 0.54, EL/EW: 1.22–1.43.

Body oval, moderately convex, dorsum surface with fine, white pubescence ( Fig. 13 View FIGURE 10 – 17 ). Head, antennae and mouthparts yellowish brown. Pronotum, scutellum and elytra reddish brown. Underside fuscous except metaventrite reddish brown.

Head small, 0.58× of pronotal width (HW/PW=0.70/1.20). Punctures on head densely and evenly, separated by 1–2 diameters, with white pubescence. Eyes small, the widest interocular distance 0.43× of head width. Pronotum 0.88× of elytral width (PW/EW=1.20/1.35), pronotal punctures fine and larger than those on head, 1–2 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 4.5 times of width at the base. Abdominal postcoxal lines incomplete, slightly recurved toward the base of ventrite ( Fig. 33 View FIGURE 28 – 37 ). Area surrounded by the line evenly punctured, relatively smooth along the line.

Male genitalia: Penis slender, with a developed penis capsule ( Fig. 34 View FIGURE 28 – 37 ), apex of penis simple ( Fig. 35 View FIGURE 28 – 37 ). Tegmen stout, penis guide slightly constricted near middle and converging gradually to a pointed tip in ventral view ( Fig. 37 View FIGURE 28 – 37 ). Parameres broad, distinctly shorter than penis guide, apex with two groups long and uniform setae ( Fig. 36 View FIGURE 28 – 37 ). Female genitalia unknown.
