Dilophotes moxiensis sp. n.

Type material. Holotype, male, " China, Moxi, east of Gongashan, 2700 m, 20.­24. vii. 1992 " ( LMBC). Paratypes: 5 males, 2 females, same locality data ( LMBC).

Diagnosis. Dilophotes moxiensis sp. n. resembles D. pacholatkoi sp. n. in the shape of male genitalia ( Figs 18 ­ 20 ). These species differ in the shape of the apical ring, which is elliptical in D. moxiensis sp. n. ( Fig. 18 ) and rounded in D. pacholatkoi sp. n. ( Fig. 20 ). These species differ also in colouration of pronotum and elytra.

Description of holotype. Body medium sized, slender, black, pronotum and elytra black, only their margins red, both covered with dense, dark red to purple pubescence. Head with short rostrum. Eyes very small, interocular distance 1.64 times maximum eye diameter. Antennae very slender, reaching beyond two thirds of elytra, basal antennomeres slightly serrate, terminal ones parallel­sided. Maxillary palpi slender, apical palpomere 1.7 times longer than wide. Pronotum 1.5 times wider than long. Frontal margin widely rounded, frontal angles inconspicuous, lateral margins slightly concave, posterior angles moderately projected ( Fig. 6 ). Pronotal disc with sharp longitudinal costa attached to frontal margin and reaching middle of pronotum. Disc surface densely pubescent, shiny. Scutellum simply rounded. Elytra very slender, flat, each elytron with three longitudinal costae in humeral part, costa 1 very weak, shortened, distinct in humeral quarter. Male genitalia with short, robust phallus, internal sac sclerotized, apical ring elliptical ( Fig. 18 ).

Measurements. BL 9.0 mm, WH 1.94 mm, PL 1.17 mm, PW 1.72 mm, Ediam 0.37 mm, Edist 0.62 mm.

Distribution. China, Sichuan Province. Until now, the species is known only from the type locality.

Etymology. The specific epithet is derived from the local name Moxi, a village at the foothill of Gongashan.
