Sasajiscymnus lishanicus Tong & Wang sp. nov.

( Figs 11 , 64)

Chinese name: 历山ḧ瓢•

Diagnosis. This species is similar to S. fusinus sp. nov., but can be distinguished from the later by the black elytra with yellowish brown apices, smaller and shorter body size, and parameres about 1/2 as long as penis guide ( Figs 11a–b, 11g ). In S. fusinus , elytra are uniformly black, body size is larger and more elongate, and parameres are about 1/3 as long as penis guide ( Figs 4a–b, 4f ).

Description. TL: 1.47–2.04 mm, TW: 1.02–1.18 mm, TH: 0.79–0.89 mm.

Body oval, moderately convex, surfaces covered with short pubescence ( Figs 11a–c ). Head black with antennae and mouthparts yellowish brown, interocular distance distinctly greater than eye width in frontal view. Pronotum black with anterior margin narrowly yellowish brown. Scutellar shield black. Elytra black with brown apices. Ventral surfaces brown to black. Legs brown. Abdominal postcoxal lines incomplete, recurved toward the base of ventrite ( Fig. 11d ).

Male genitalia: Penis long and slender, penis capsule with short outer arm and long inner one, apex of penis pointed ( Figs 11e–f ). Penis guide triangular in lateral view with pointed apex; parameres about 1/2 as long as penis guide, with a tuft of long setae at apex; penis guide approximately widest at 1/2 length in ventral view, bifurcated apically ( Figs 11g –h ).

Female genitalia: Coxites distinctly elongate, triangular; styli strongly reduced and hardly visible; spermatheca distinctly curved, with basal ramus and nodulus.

Type material. Holotype: China: Shanxi: ♂, Lishan National Nature Reserve , 800–1400 m, 3.VIII.2011, Wang XM leg ( SCAU) . Paratypes ( SCAU): China: Shanxi: 5♂ 4♀, Heilongtan, Dahe Village, Lishan National Nature Reserve , 995 m, 17.VII.2013, Huo LZ leg.

Distribution. China (Shanxi).
