(Figs 1– 4, 10–14)
Mimothestus annulicornis, Pic, 1935: 16; Gressitt, 1940: 7; Breuning, 1943: 273; Chiang, 1951: 47; Gressitt, 1951: 364; Breuning, 1961: 335; Yiu, 2009: 78.
Male. Length 28–35 mm, humeral width 8.5–9.0 mm. Body black, covered with dense, light reddish brown pubescence. Antennomeres 1–7 with fringe of long black hairs ventrally, second and third densest, sixth and seventh fringed apically; second antennomere and apices of remaining antennomeres black to brownish black, basal half of antennomeres clothed with grayish white or grayish yellow pubescence from fourth through eleventh. Posterior of lateral pronotal tubercle, posterior of procoxa and mesocoxa, most of metacoxa, base of profemur, inner side of mesofemur and mesotibia, and inner side of metafemur and metatibia clothed with grey white pubescence. Disc of elytron scattered with irregular black pubescent spots; margin and suture of elytron clothed with grayish white pubescence. Head with sparse fringe of black hairs around eyes; basal half of pronotum with sparse erect black hairs; anterior half of pronotum and elytron with sparse short bristles.
Frons subquadrate, with a smooth, longitudinal median sulcus extending to occiput. Lower eye lobe longer than broad, 2.5 times as long as gena. Antenna twice as long as body; antennal tubercle strongly raised, scape cylindrical; third antennomere longer than fourth, about twice as long as scape. Pronotum 1.6 times broader than long, lateral tubercle acute; disc with a glabrous, longitudinal dark area at middle, sometimes reduced and forming a dark line; disc with sparse punctures apically, with irregular transverse rugae at center, granulate on sides of mid-line basally and posterior of lateral tubercle. Scutellum lingulate, with a glabrous, longitudinal dark medium line posteriorly. Elytra long; lateral margins slightly expanded outwards behind the middle; basal surface punctate-granular, apex of elytron rounded, sutural angle without spine. Legs short, mesotibia with an oblique groove near external apex, mesosternal intercoxal process obliquely sloping anteriorly, not tuberculate; claw widely divergent.
Material examined. One male, Yuanjiang, Yunnan, 13 July 2008, collected by Xin-yong Huang; one male, Lücongpo, Badong, Hubei, 14 July 2006, collected by Man Li; one male, Wuming, Damingshan, Guangxi, 28 June 2008, collected by Cheng-hui Zhan.
Discussion. Fresh specimens of this species are normally bright-colored, with reddish-orange pubescence, older specimens are often darker with reddish brown or terracotta pubescence. The black elytral spots present variable from very small (Fig. 1) to very large and irregular (Fig. 2). This is the most commonly found species in Mimothestus and can be distinguished from other known species by the dorsal color and pubescent pattern on the elytra.
Distribution. China (Hubei, Guangdong, Guangxi, Hong Kong, Guizhou, Yunnan), Cambodia.
