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) yanzigouensis sp. n. Figs 8, 12 Diagnosis . This species is similar to Scymnus (Parapullus) nanlingicus Chen, Ren & Wang, 2012 in general appearance and male genitalia, but can be separated from it by having broad area enclosed by abdominal postcoxal lines (Fig. 8d) and the parameres narrowest at base, expanding toward apex in lateral view (Fig. 8h). Figure 8. Scymnus (Parapullus) yanzigouensis 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: 2.20-2.42 mm, TW: 1.52-1.67 mm, TH: 0.99-1.05 mm, TL/TW: 1.45, PL/PW: 0.51, EL/EW: 1.13-1.14, HW/PW: 0.56-0.58, PW/EW: 0.73-0.74. Body oval, moderately convex, dorsum covered with white pubescence (Fig. 8 a-c ). Head, antennae and mouthparts brown. Pronotum yellowish brown. Scutellum dark brown. Elytra black with apical 1/4 yellowish brown. Prothoracic hypomeron and prosternum yellowish brown. Mesoventrite, metaventrite and elytral epipleura black. Legs brown. Head with fine frontal punctures, as large as eye facets, 0.5-1.0 diameters 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 rectangular, 2 times as long as its width at base; with lateral carinae distinct, parallel, extending to anterior margin of prosternum. Abdominal postcoxal lines strongly recurved and distinctly incomplete laterally (Fig. 8d), reaching 7/8 length of abdominal ventrite 1, area enclosed by lines irregularly punctate, broadly smooth along line. Abdominal ventrite 5 in male with apex truncate. Male genitalia: penis stout (Fig. 8e). Penis capsule with outer arm stout and inner arm strongly curved, hook-shaped. Apex of penis simple (Fig. 8f). Tegmen stout (Fig. 8 g-h ) with penis guide parallel sided from base to 4/5 length, then tapering abruptly to blunt apex in ventral view (Fig. 8g). Parameres narrowest at base, expanding toward apex, distinctly shorter than penis guide, densely covered with two groups of long setae at apices (Fig. 8h). Female unknown. Type materials. Holotype: male, No. SCAU (E) 11531, China: Sichuan: Yanzigou, Gonggashan National Nature Reserve, Luding County, 29°41.92'N , 102°0.22'E , ca 2500 m, 28. IX. 2007, Chen XS leg.
