Mimopodabrus multidentatus sp. nov.

( Figures 1B, 2 E–H)

Male ( Figure 1B )

Body length from apex of clypeus to apices of elytra 5.2 mm, maximal width on elytra 1.3 mm. Head red, behind eyes black, mouthparts red, antennae orange, apices of antennomeres III–VII dark, pronotum red, with a broad median longitudinal black marking, scutellum and elytra black, legs orange, apices of tibiae and tarsi black, meso- and meta-ventrites black, abdominal ventrites black, posterior margins orange. Body densely covered with short black pubescence.

Head. Eyes moderately protruding, breadth of head across eyes slightly wider than anterior margin of pronotum, head behind eyes roundly narrowed posteriorly, temple longer than longitudinal width of an eye, head surface finely and densely punctuate; apical maxillary palpomere longest, widened apically and arcuated; antennae ( Figure 2H ) extending to middle of elytra, thickened, antennomeres II as long as wide, III parallel-sided, with a small round fovea near apex, IV–VII widened apically, each with a fovea near apex, inner margins of foveae on IV–VII raised upwards, tooth-like in lateral view, VIII–XI parallel-sided.

Pronotum. Longer than wide, subquadrate, slightly widened posteriorly, anterior margin straight, anterior angles obtusely rounded, lateral margins nearly straight, posterior angles vertical, posterior margin straight; disc slightly convex on both sides, finely punctuate.

Elytra. About four times longer than pronotum, combined at shoulder one-third wider than posterior margin of pronotum, parallel-sided, surface matt, finely punctuate.

Legs. All tarsal claws bifid, pro-tarsal claws shallowly split from apex, meso- and metatarsal claws deeply split.

Aedeagus ( Figure 2 E–G). Ventral processes of parameres stout, with obtusely pointed apices; dorsal plates of parameres tapered and apex bent ventrally; laterophyses separate from each other, on both sides of median lobe, next to ventral processes of parameres.

Female

Head, antennae, legs and abdomen uniformly black; eyes smaller and less protruding, head across eyes as wide as anterior margin of pronotum; antennae simple filiform, shorter and narrower; pronotum slight wider than long, lateral margins parallelsided; all tarsal claws simple, not toothed or bifid.

Variation in paratype series

Sometimes male antennae uniformly orange, femora with black apices and outer sides, abdomen uniformly orange. Body length 5.2–5.4 mm, width 1.3–1.5 mm.

Type material

Holotype. 3, China, Kwangtung, Kan-Lin San, M. Lien Ping Distr., 700–900 m, 20 April 1940, J.L. Gressitt and P.K. To leg.

Paratypes. 333, 2♀♀, the same data as holotype . Holotype in IZAS, paratypes in IZAS and SYSU .

Etymology

This specific name is derived from Latin “ multi -” + “ dentatus ” = several (prefix) + toothed, referring to its inner margins of foveae on antennomeres IV–VII raised upwards, tooth-like in lateral view.

Remarks

This new species is similar to M. jendeki Wittmer , but can be easily distinguished from all others of this genus by its male antennae tooth-like in lateral view and female tarsal claws simple.
