Description.
Length of body: 7.6 mm; length of elytra: 5.1 mm; maximum width: 4.4 mm. Body yellowish brown, head darker. Surface of labroclypeus and disc of frons glabrous. Smooth area anterior to eye twice as wide as long. Eyes moderately large, ratio of diameter/interocular width: 0.68. Ratio of length of metepisternum/metacoxa: 1/1.59. Metatibia short and wide, ratio width/length: 1/3.09; basal group of dorsal spines of metatibia at first third of metatibial length.
Aedeagus: Fig. 38 E–G. Habitus: Fig. 38H.
Variation.
Length of body: 7.1-7.6 mm; length of elytra: 5.0-5.1 mm; maximum width: 4.1-4.4 mm. Female: Antennal club with three antennomeres, as long as remaining antennomeres combined; eyes as large as in male; pygidium weakly convex at apex.
Diagnosis.
Tetraserica semishanensis sp. n. differs from the similar T. shanensis sp. n. by the narrower, nearly straight ventral lobe of left paramere (lateral view) and the dorsal lobe of left paramere being nearly evenly narrowed towards apex (rather than bluntly widened before apex, as in T. shanensis ).
Etymology.
The species name (adjective in the nominative singular) is derived from the combined Latin words semi- (half) and the species name shanensis , with reference to the similarity to T. shanensis sp. n.
