description: Mimothestus luteicornis, sp. nov.
(Figs 6–9, 15–16)
Female. Length 26–29 mm, humeral width 8.0–9.0 mm. Body reddish brown to black, covered with dense luteous pubescence. Head, antenna, leg and ventral surface evenly covered with pubescence; pronotum and elytron pubescence intermixed with denuded dark areas giving a mottled appearance. Antennomeres 2–10 densely fringed with long hairs ventrally, scape and terminal antennomere sparsely fringed; antennomeres 1 and 2 dark brown, remaining antennomeres lighter reddish brown with darker brown apices. Head clothed with sparse, semirecumbent, dark reddish brown hairs (the hairs almost erect in one paratype from Hainan); pronotum and elytron similar in vestiture but with intermixed denuded areas giving a mottled appearance.
Frons subquadrate, with a smooth, longitudinal median sulcus extending to occiput; vertex considerably depressed. Eye finely faceted, lower lobe slightly longer than broad, 2.5 times as long as gena. Antenna 1.2 times as long as body; antennal tubercle strongly raised; scape cylindrical, robust; third antennomere longer than fourth, 1.7 times as long as scape; antennomeres successively shorter in length from fourth through eleventh. Pronotum 2.1 times broader than long; lateral tubercle acute, anterior margin slightly concave; disc with scattered coarse punctures apically, granulate basally; Scutellum lingulate. Elytra long, narrow, gradually separated along suture after basal fourth (suddenly separated at apical fifth in one paratype from Hainan); lateral margins subparallel, apex rounded, sutural angle spined; elytral surface dotted with dense, coarse punctures and fine granules, punctures deepest basally, gradually shallower towards apex, granules larger basally, gradually smaller towards apex; pubescent areas on elytral surface almost devoid of punctures or granules. Mesosternum with intercoxal process obliquely sloping anteriorly, not tuberculate. Posterior margin of terminal sternite distinctly concave. Legs short, stout, mesotibia with an oblique groove near external apex, metafemur not exceeding second abdominal segment.
Male. Unknown.
Type material. Holotype, female, CHINA: Wuming, Damingshan, Guangxi, 28 June, 2008, collected by Cheng-hui Zhan; paratypes, one female, CHINA: Nanling Natural Reserve, Guangdong, 15 June, 2009, collected by Cheng-hui Zhan; one female, CHINA: Bawangling, Changjiang Hainan, 5 May, 2010, collected by Wei Li. Holotype and paratypes are deposited in the Entomological Museum, Yangtze University, Jingzhou, Hubei, P. R. China.
Discussion. We were unable to examine the type of M. delkeskampi. Breuning’s original description indicates that M. delkeskampi and M. luteicornis sp. n. are similar in their appearance. For example, both species have antennomeres 3–11 clothed with dark brown pubescence and hairs apically; pronotum and elytra with dark mottling; sutural angle with a distinct spine. However, M. luteicornis sp. n. can be distinguished from M. delkeskampi by its lower eye lobe about 2.5 times as long as gena, pronotal disc granulate basally with coarse punctures apically, elytral surface with fine granules and coarse punctures, and body pubescence luteous.
Distribution. China (Guangdong, Guangxi, Hainan).
Etymology. The new species is named for the antennae, which are mostly clothed with luteous pubescence and hairs.
