Dilophotes lizipingensis sp. n.

Type material. Holotype, male, " China, Sichuan, Liziping, 28. 6.­3. 7. 1991" ( LMBC). Paratypes: 1 male, 1 female, " China, W. Guizhou prov., Leigongshan, Xijiang, 29. 5.­2. 6. 1997, 1200­1900 m, Bolm leg." ( LMBC).

Diagnosis. Dilophotes lizipingensis sp. n. has flabellate male antennae but it is similar in body colouration to the dark red species belong to the other species groups based on their structure of male genitalia. Within groups having flabellate antennae it is well defined by the shape of its phallus and internal sac ( Fig. 23 ).

Description of holotype. Body medium sized, slender, black, pronotum black with brown margins, elytra dark brown to black, only humeri brownish red, both body part covered with dark red dense pubescence. Eyes small, interocular distance 1.38 times maximum eye diameter. Head with short rostrum. Antennae flabellate, lamella of antennomere 7 3.5 times trunk of antennomere ( Fig. 4 ). Pronotum transverse, 1.5 times wider than long, frontal margin widely rounded, frontal angles inconspicuous, lateral margins very slightly concave, posterior angles slightly projected ( Fig. 7 ). Disc with sharp longitudinal costa from frontal margin almost reaching posterior margin. Disc surface densely pubescent. Scutellum simply rounded. Elytra very slender, flat, each elytron with three longitudinal costae. Costa 1 and 2 weak, costa 3 strong especially in humeral quarter. Male genitalia with short phallus and partly sclerotized internal sac ( Fig. 23 ).

Measurements. BL 6.5 mm, WH 1.65 mm, PL 0.93 mm, PW 1.43 mm, Ediam 0.40 mm, Edist 0.55 mm.

Distribution. Dilophotes lizipingensis sp. n. should be widely distributed species in China, but at present it is known only from two distant localities in western Sichuan and Guizhou.

Etymology. The specific epithet is derived from the local name Liziping in Sichuan, China.
