Description. Body length: 19.6–20.9 mm . Female measurements (mean, n = 4): HL: 3.54; HW: 3.82; CL: 0.98; PO: 2.40; PL: 3.75; PW: 3.38; EL: 3.35; EW: 3.74; ELS: 1.57. Male measurements (n = 1): HL: 3.43; HW: 3.53; CL: 0.98; PO: 2.25; PL: 3.35; PW: 3.08; EL: 3.23; EW: 3.32; ELS: 1.67. Male. Body elongate, black, dull, pubescence on sides of 3–5 th abdominal tergites and base of 7 th abdominal tergite silver-yellow, pubescence of 6 th , 8–9 th and remaining part of 7 th tergite black. Maxillary palpi brown, apex of last segment slightly paler, tibiae yellow and tarsi brown. Head ( Fig. 1A ) large, subquadrate, not widened backward, sides almost straight; eyes small, oval, distinctly protruding, but not from lateral outline of head, longitudinal diameter much shorter than postocular area; base broadly and shallowly emarginate, posterior angles obviously protruding backward with apices rounded; surface densely covered with umbilicate punctures, with short yellow pubescence. Antennae ( Fig. 1G ) short and stout, hardly reaching midlength of pronotum, moderately thickened and more opaque apicad, last segment asymmetrical, sharply pointed; ratios of antennomere length (1 to 11) as follows: 20:17:15:14:15:16:13:15:22:13:30. Pronotum nearly horseshoe-shaped and convex, longer than wide, slightly narrower than head, widest at anterior margin, anterior margin raised medially, sides subparallel, gradually narrowed toward base; anterior angles pointed, posterior angles widely rounded; surface densely and regularly covered with umbilicate punctures, coarser anteriorly; with shiny impunctate midline, becoming indistinct and almost obsolete at about midlength; pubescence similar to that on head. Scutellum triangular, densely covered with black velvety pubescence. Elytra short, nearly quadrate, slightly dilated posteriad, wider than long, a little shorter and broader than pronotum; sides straight, posterior margin slightly emarginate medially; surface feebly and densely punctate, covered with dense black and sparse golden yellow pubescence. Abdomen elongate and gradually widened posteriad; surface finely and densely punctate, 3–5 th tergites with black pubescence in middle and patches of yellow pubescence laterally, patches gradually decreasing in size towards apex, 7 th tergite also with transverse patch of golden pubescence at base; posterior margin of 8 th sternite ( Fig. 1B ) broadly and deeply emarginate medially, surface of tergite bearing moderately long golden pubescence. 10 th tergite ( Fig. 1C ) with golden pubescence in basal half, 9 th sternite ( Fig. 1E ) triangularly excised in middle of posterior margin and with pyramid-shaped deep depression at base. Legs robust, first four protarsal segments markedly dilated, sub-bilobed, each covered with golden setae. FIGURES 1A–K. Naddia nanlingensis Yang & Zhou sp. n. , male (A–C, E, G–K, holotype) and female (D, F, paratype). A—head; B—8 th sternite; C–D—10 th tergite; E—9 th sternite; F—detail of genital segment with second gonocoxite; G— antennae; H—detail of paramere; I—aedeagus, ventral view; J—aedeagus, lateral view; K—aedeagus, dorsal view. Scale bar 1mm. Aedeagus ( Figs. 1H–K ) symmetrical; median lobe elongate, with weakly sclerotized middle part and globular basal part, in ventral view median lobe feebly narrowed towards round apex, in lateral view moderately curved ventrad; paramere ( Fig. 1H ) degenerate, very fine and slender, with four short setae medioapically. Female. First four protarsal segments similar to those of male. Second gonocoxite ( Fig. 1F ) with minute stylus bearing two equally long apical setae, basal half of second gonocoxite with long golden setae. 10 th tergite ( Fig. 1D ) triangular, moderately wide, apex broadly arcuate, with long golden setae at and near apical margin. Distribution. China ( Guangdong ). Notes. In general appearance, the present new species is similar to Naddia taiwanensis Shibata, 1979 from Taiwan , but the latter has distinctly divergent posterior areas of head, orange-red pubescence on the elytra and shiny impunctate midline on pronotum. Etymology. The species is named after the type locality, Nanling National Nature Reserve in Guangdong Province , China .
