Contribution to the knowledge of the subgenus Scymnus (Parapullus) Yang, 1978 (Coleoptera, Coccinellidae), with description of eight new species Author Chen, Xiaosheng Author Ren, Shunxiang Author Wang, Xingmin text Deutsche Entomologische Zeitschrift 2015 62 2 211 224 http://dx.doi.org/10.3897/dez.62.5285 journal article http://dx.doi.org/10.3897/dez.62.5285 1860-1324-2-211 075E22007B72481B8D1587708FD1A8BE Taxon classification Animalia Coleoptera Coccinellidae Scymnus (Parapullus) shenmuensis sp. n. Figs 7, 12 Diagnosis. This species is similar to Scymnus (Parapullus) secula Yang, 1978 in general appearance and male genitalia, but can be separated from it by the brown pronotum with a large black marking (Fig. 7 a-b ) and the apex of penis stout, hook-shaped (Fig. 7f). Figure 7. Scymnus (Parapullus) shenmuensis sp. n.: a dorsal view; b anterior view; c lateral view; d abdomen; e penis; f apex of penis; g tegmen, ventral view; h tegmen, lateral view. Scale bars: a-c 0.5 mm, d 0.2 mm, e-h 0.1 mm. Description. TL: 2.18 mm, TW: 1.46 mm, TH: 0.98 mm, TL/TW: 1.49, PL/PW: 0.46, EL/EW: 1.20, HW/PW: 0.57, PW/EW: 0.77. Body elongate oval, slightly convex, dorsum covered with white pubescence (Figs 7 a-c ). Head, antennae and mouthparts dark brown. Pronotum brown with a large black marking. Scutellum black. Elytra black with apical 1/6 yellowish brown. Prothoracic hypomeron and prosternum brown. Mesoventrite, metaventrite and elytral epipleura black. Legs brown. Head with fine frontal punctures, slightly larger than eye facets, 0.5-1.0 diameter apart. Eyes densely faceted, interocular distance 0.50 times head width. Pronotal punctures as large as 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 times as long as its width at base; with lateral carinae distinct, extending to anterior margin of prosternum, slightly convergent anteriorly. Abdominal postcoxal lines strongly recurved and distinctly incomplete laterally (Fig. 7d), reaching 5/6 length of abdominal ventrite 1, area enclosed by lines irregularly punctate, narrowly smooth along line. Abdominal ventrite 5 in male with apical margin shallowly emarginated medially. Male genitalia: penis stout (Fig. 7e). Penis capsule with small inner arm and large outer arm. Apex of penis stout with membranous appendage, hook-shaped (Fig. 7f). Tegmen stout (Figs 7 g-h ) with penis guide narrowest at base, expanding toward apex, then tapering abruptly to blunt apex in ventral view (Fig. 7g) and its apex slightly curved outwardly in lateral view (Fig. 7h). Parameres slightly curved at base, distinctly shorter than penis guide, densely covered with two groups of long setae at apices (Fig. 7h). Female unknown. Type material.
