Anaedus pluridentatus sp. nov.

( Figs. 21–23 , 28 )

Type material. Holotype: Ψ, deposited in HBUM. Mountain Jinyun, Chongqing, China, 8 July, 2002, collected by Bai Ming and Wang Jian-Feng.

Diagnosis. The new species can be distinguished from A. spinicornis Kaszab, 1973 by the following characters: elytral margins distinctly serrated through most of length; body size larger than 9.0 mm.

Etymology. The specific name is derived from the Latinized words “pluri-” and “dentatus”, referring to the dentate lateral elytral margins.

Description. Body oval, flat and elongate; brown, maxillary palpi black; dorsum covered with slightly short pubescence, erect on head, while those on pronotum and elytra recumbent and bend backwards.

Labrum oblong and produced with coarse punctures; clypeus slightly convex and coarsely punctate, middle of frontclypeal suture straight, indistinct at sides; frons with oblong punctures, and with three smooth carinae bearing from the same point; maxillary palpi with securiform terminal segments. Antennae robust, reaching base of pronotum; 3rd to 10th antennomeres cylindrical, subequal in size each other, about 2.7 times as long as 2nd antennomere; last antennomere elongate, with cuspidal apex.

Pronotum transverse, about 1.5 times as broad as long, broadest at middle; anterior margin moderately emarginate, widely truncate in middle, lateral margins very narrowly bordered, strongly and evenly arcuate except for the distinctly constricted just before basal angles; middle of posterior margin widely and distinctly arcuate; anterior angles obtusely rounded and reaching middle of eyes; posterior angles acute, pointing outwards; disc convex, coarsely and densely punctate, with irregular carinae between punctures; midline evident and without punctures, flattened sides with coarse punctures.

Scutellum triangular and without punctures; elytra about 1.4 times as long as broad, boarder than the pronotum; with fine and serrate teeth in basal two-thirds and some of them at apical sixth of elytra, shoulders rounded; elytra and pseudopleura with similar punctures as those on pronotum. Tibiae simple, gradually broadening towards apex; length ratio of 1st to 4th tarsomeres of metatarsus from base to apex: 6.0: 2.0: 1.0: 4.0.

Propleura smooth, with a few punctures; prosternum, V-shaped area of mesosternum and pleura coarsely punctate; punctures on metasternum sparse, abdominal sternites finely punctured; metasternum between coxae with an impunctate round impression; last abdominal ventrite broadly triangular.

Measurement. Body length: Ψ 9.4 mm; width: Ψ 4.3 mm.

Male. unknown.

Distribution. China (Chongqing)
