Scymnus (Parapullus) secula Yang, 1978: 27 ; Pang and Yu, 1993: 229; Yu et al., 2000: 167; Pang et al., 2004: 82; Kovář, 2007: 584; Ren et al., 2009: 68.

Diagnosis. This species is similar to S. (P.) nanlingicus in general appearance, but can be distinguished by the elytra black with apical 1/7 yellow. The penis guide in ventral view is diagnostic.

Description. TL: 2.43 mm, TW: 1.55 mm, TH: 1.00 mm, TL/TW: 1.57, PL/PW: 0.45, EL/EW: 1.23.

Body oval, moderately convex, dorsum surface with fine, white pubescence ( Fig. 16 View FIGURE 10 – 17 ). Head, antennae and mouthparts yellowish brown. Pronotum yellowish brown. Scutellum black. Elytra black with apical 1/7 yellow. Underside yellowish brown except mesoventrite, metaventrite and elytral epipleuron black.

Head small, 0.59× of pronotal width (HW/PW=0.65/1.10). Punctures on head smaller than eye facets, separated by 1–2 diameters, with white pubescence. Eyes small and almost oval, rather coarsely faceted, the widest interocular distance 0.54× of head width. Pronotum 0.71× of elytral width (PW/EW=1.10/1.55), pronotal punctures finer 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 3.5 times width at base. Abdominal postcoxal lines incomplete, slightly recurved toward the base of ventrite ( Fig. 48 View FIGURE 48 – 57 ). Area surrounded by the line evenly and densely punctured, relatively narrowly smooth along the line.

Male genitalia: Penis slender, penis capsule with a distinctly quadrangle outer process ( Fig. 49 View FIGURE 48 – 57 ). Apex of penis curved, sickle-like ( Fig. 50 View FIGURE 48 – 57 ). Tegmen stout, penis guide straight, widest at base in lateral view ( Fig. 51 View FIGURE 48 – 57 ); in ventral view, penis guide narrow at base, converging gradually apical to a pointed tip ( Fig. 52 View FIGURE 48 – 57 ).Parameres shorter than penis guide, apex with two groups long and uniform setae ( Fig. 51 View FIGURE 48 – 57 ). Female genitalia unknown.

Type. Not examined.
