Scymnus (Parapullus) papillatus sp. n. Figs 5, 11

Diagnosis.

This species is similar to Scymnus (Parapullus) solus Chen, Ren & Wang, 2012 in general appearance and male genitalia, but can be separated from it by having a papilla bearing a stout seta at the apical 1/3 length of paramere (Fig. 5h).

Description.

TL: 1.98-2.36 mm, TW: 1.39-1.66 mm, TH: 0.92-1.09 mm, TL/TW: 1.42, PL/PW: 0.50-0.55, EL/EW: 1.09-1.12, HW/PW: 0.59-0.60, PW/EW: 0.70-0.73.

Body elongate oval, moderately convex, dorsum covered with white pubescence (Fig. 5 a–c). Head, antennae and mouthparts brown. Pronotum dark brown. Scutellum black. Elytra black with apical 1/4 brown. Prothoracic hypomeron and prosternum brown. Mesoventrite, metaventrite and elytral epipleura black. Legs brown.

Head with fine frontal punctures, as large as eye facets, 0.5-1.0 diameter apart. Eyes densely faceted, interocular distance 0.50 times head width. Pronotal punctures larger than those on frons, 1.5-3.0 diameters apart. Surface of elytra with punctures as large as those on pronotum, separated by 1.0-2.0 diameters. Prosternal process trapezoidal, 2.3 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. 5d), nearly extending to posterior margins of abdominal ventrite 1, area enclosed by lines finely punctate, narrowly smooth along line. Abdominal ventrite 5 in male with apex truncate.

Male genitalia: penis stout and long (Fig. 5e). Penis capsule with outer arm large and inner arm strongly curved. Apex of penis unevenly curved, forming a large hook (Fig. 5f). Tegmen stout (Fig. 5 g–h) with penis guide narrowest at base, expanding toward apex, then tapering abruptly to blunt apex in ventral view (Fig. 5g). Parameres obliquely truncated apically, longer than half length of penis guide, densely covered with a group of long setae at apices, and its apical 1/3 length with a papilla bearing a stout seta on inner side (Fig. 5h).

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