Scymnus (Parapullus) laojielingensis sp. n. Figs 3, 10

Diagnosis.

This species is similar to Scymnus (Parapullus) parallelicus Chen, Ren & Wang, 2012 in general appearance and male genitalia, but can be distinguished from it by having strongly sinuated apex of penis with membranous appendage (Fig. 3f), the apical 1/4 length of parameres covered with several long setae at inner sides in lateral view (Fig. 3h), and the area enclosed by the abdominal postcoxal lines with coarse punctures (Fig. 3d).

Description.

TL: 2.21-2.38 mm, TW: 1.58-1.71 mm, TH: 1.01-1.16 mm, TL/TW: 1.39-1.40, PL/PW: 0.51-0.52, EL/EW: 1.08-1.12, HW/PW: 0.56, PW/EW: 0.72.

Body elongate oval, moderately convex, entirely reddish brown, dorsum covered with white pubescence (Fig. 3 a–c).

Head with fine frontal punctures, as large as eye facets, 0.5-1.0 diameter apart. Eyes densely faceted, interocular distance 0.47 times head width. Pronotal punctures similar to those on frons, 1.0-2.0 diameters apart. Surface of elytra with punctures larger than those on pronotum, separated by 2.0-3.0 diameters. Prosternal process trapezoidal, 2.5 times as long as its width at base; with lateral carinae distinct, extending to anterior margin of prosternum, distinctly convergent anteriorly. Abdominal postcoxal lines weakly recurved and distinctly incomplete laterally (Fig. 3d), reaching 5/6 length of abdominal ventrite 1, area enclosed by lines coarsely punctate, narrowly smooth along line. Abdominal ventrite 5 in male with apex rounded.

Male genitalia: penis stout (Fig. 3e). Penis capsule with small inner arm and large outer arm. Apex of penis strongly sinuated with membranous appendage (Fig. 3f). Tegmen stout (Fig. 3 g–h) with penis guide with parallel sides from base to 3/4 length, then tapering gradually to blunt apex in ventral view (Fig. 3g) and its apex slightly curved outwardly in lateral view (Fig. 3h). Parameres longer than half length of penis guide, densely covered with a group of long setae at apices, and its apical 1/4 length covered with several stout setae at inner sides (Fig. 3h).

Female externally similar to male but with abdominal ventrite 5 truncate apically.
