description: 4. Sinodorcadion magnispinicolle, sp. nov.
(Figs 15–20, 35)
Material examined. Holotype, female, China: Zhejiang, Fengyangshan, Fengyanghu station, 24 July 2007, leg. Guang-lin Xie, by sweep net, altitude 1540 m. The holotype is deposited in the Entomological Museum, Yangtze University (YZU), Jingzhou, Hubei, P. R. China.
Description. Female. Length 9.0 mm, maximum width of elytra 3.5 mm. Body fuscous to black, antenna dull reddish brown except for scape and apices of antennomeres 3–11 blackish brown. Surface covered with grayyellow pubescence. Pubescence on elytron nonuniform, forming scattered patches of various sizes and shapes. Some of which coalesce into a vague broad transverse band at the middle of basal half, not reaching suture, the rest snatchy.
Head densely punctate, punctures on frons coarser than vertex, occiput and gena; frons wider than long, slightly convex; lower eye lobe longer than broad, longer than gena in front view. Antenna slightly longer than body; antennal tubercles prominent, widely separated from each other; scape cylindrical, robust, about as long as antennomere 4; antennomere 3 longest, about 2 times as long as scape. Pronotum densely punctate, broader than long, lateral tubercle well developed, conical, obtuse; anterior margin broader than posterior margin, disc convex; punctures on central portion coarser than both sides. Elytra relatively convex, broadest across middle, markedly narrow from the middle to apices, obliquely truncate apically, external angle of apex rounded; punctures on surface coarser than pronotum, successively becoming finer towards to apices. Sterna sparsely punctate except for central portion of posterior margin of metasternum impunctate. Sternites impunctate except for both sides of basal two segments distinctly punctate. Last visible abdominal segment extends the apices of elytra.
Male. Unknown.
Female genitalia. Bursa copulatrix elongate, not swelling; spermatheca is borne on apex of bursa copulatrix, consisting of a basal membranous tube and apical strongly sclerotized part, basal tube strongly curved, nearly Ushaped, apical part consisting of a basal stalk and apical cudgel, basal stalk vertically joins with the mesio-middle of apical cudgel and forming T-shaped structure, apical cudgel with one side strongly expanded and rounded distally, the other side thin and slightly bended distally; spermathecal duct is borne at the apex of bursa copulatrix; spermathecal gland is borne at the joint of membranous and sclerotized part of spermatheca.
Comments. The new species is distinguished from S. subspinicolle Breuning by its ventral surface punctate, lateral pronotal tubercle well developed and different elytral pubescent maculae. It differs from S. jiangi sp. nov. in having mesosternum with distinct punctures and more broad body and more developed lateral pronotal tubercle. It differs from S. punctulatum Gressitt in having antenna with apex of each antennomere blackish brown, legs completely blackish brown, lateral pronotal tubercle well developed and elytra with conspicuous pubescent maculae.
Xie et al (2010) once identified the new species as the female of S. punctulatum Gressitt. After examining more specimens including both sexes collected in recent years, we concluded that this female collected from Fengyangshan was an undescribed species.
Distribution. China (Zhejiang).
Etymology. The new species is named for pronotum with well developed lateral tubercles.
