Diagnosis

External morphology of adult (Fig. 63). Body size 16.5–17.2 mm. Dorsal surface densely pubescent. Clypeus shorter than frons, with anterior edge moderately emarginate at middle, oblique laterally. Frons with carina bent backward at middle. Pronotal anterior margin with short setae and without concavity at each lateral end; posterior margin finely flanged; lateral margins strongly serrated, with short setae and moderately reflexed upwards; anterior and posterior angles obtuse. Prosternal process nearly trapezoidal-shaped. Scutellum pubescent. Elytra with pubescence, longer on basal surface; epipleuron with pubescence on full length. Foretibia with moderately developed dorsal carina; insertion of inner spur closer to second outer tooth than third one in male. Meso- and metatibia with interrupted and complete transverse carina, respectively; inner margin of dorsal surface with spines. Prepygidium densely punctate. Pygidium pubescent, roughly and irregularly punctate. Ventrites with dense, short and decumbent setae; ventrite 5 with long pubescence; ventrite 6 moderately concave and bulging at anterior margin. Male genitalia: parameres (Fig. 64) with dorsal branches and collum continuous, apices downward; ventral branches with apices moderately curved upwards. Female genitalia not studied.

Material examined

Holotype CHINA • ♂; Chang Shou, Nanmu Yuan [Chang Shou, a district in Chongqing]; 6 May 1994; Ke-yi Wang leg.; “HOLOTYPE”; “ Holotrichia (Pledina) wangi Zhang. sp. nov. det. You-wei Zhang, 1995 V ”; “Coll. Nº Scarab-13”; “IOZ(E)218205”; IZCAS.

Remarks

Zhang & Li (1997) described Holotrichia wangi based on a male specimen from Sichuan in China. Bezděk (2016) transferred this species to Miridiba . We have studied the holotype, which shows features of external morphology and male genitalia characteristic of Miridiba and morphotype I “ Trichophora ”. Hence, this species is included in this genital morphotype.

Distribution
