description: Denierella striolata sp. nov.
(Figs 1–2, 7, 10, 13–17)
Male (Fig. 1). Body length 15–19 mm, maximal width on elytra 4.0–5.0 mm. Body black, head yellowish-red, clypeus yellowish-red with a dark median latitudinal band, labrum black but yellowish-red apically in the middle. Gray pubescence on the following body parts: maxillary palpomeres II–III, antennomeres I–III ventrally, pronotum laterally and along the posterior margin, elytron in longitudinal middle and along outer, inner and apical margins, head and thorax ventrally, posterior margins of abdominal sternites, around all coxal cavities, femora externally, tibiae and profemur internally; median longitudinal light pubescent stripe of elytron as broad as that along outer margin, and nearly extending to the apex; metasternal pubescence hardly light. Very long black setae on the following body parts: maxillary palpomeres II–III ventrally, antennomeres I–V and base of VI, metasternum medially and abdominal sternites entirely, around all coxal cavities, pro-femur, tibia and tarsomere I externally, meso-, meta-femur and tibia internally and ventrally.
Head (Fig. 7) subquadrate, templa parallel with angles rounded, posterior margin straight, vertex with a dark median longitudinal line; finely and sparsely punctate, surface between punctures shiny; frons with a pair of impunctate ovate areas at inner base of antennae. Clypeus slightly coarsely punctate, but smooth at the anterior margin. Labrum apically slightly convex in the middle. Last maxillary palpus longest and triangular. Antenna thick, reaching two-thirds of body, antennomere II three times as long as wide, III about twice II, IV one-third shorter than III, VI slightly longer than V, VII–X gradually thinner and shorter, XI slightly longer and tapering.
Pronotum narrower than head, longer than wide, widest at nearly anterior one-third, then strongly narrowed forwards and almost parallel-sided backwards; finely and very densely punctate, surface between punctures shiny, with a smooth median longitudinal line, hardly depressed at base.
All tarsal claws (Fig. 10) covered with large teeth ventrally along the dorsal blades. Protarsomere I not modified, about 1.5 times as long as II; protibia with 2 similar spurs, slightly long, thin and pointed. Metatibia with 2 spurs flattened and wedge-shaped, the outer one slightly wider.
Elytra one-third wider than pronotum at base, elongate and parallel-sided, humeri less-angled, weakly, very finely and densely punctate. Ventral surface of body shiny; abdominal sternite IX with posterior margin emarginated in the middle. Abdominal tergite IX (Fig. 13) about twice as wide as long, anterior margin almost straight, posterior margin slightly emarginated in the middle, coarsely and densely punctate.
Spiculum gastrale (Fig. 14) Y-shaped, lateral arms with apex semi-roundly emarginated and inner angles acute, slightly darker along inner margin. Phallobase (Fig. 15) with apodeme round, parameres 1.8 times as long as apodeme, split at apical one-third in the middle, very sparsely and indistinctly micropunctate and light pubescent. Aedeagus with distal hook as in Fig. 16, endophallic hook smaller than the aedeagal one.
Female (Fig. 2). Antenna thinner, reaching the middle of the body. Frons with impunctate areas very small. Maxillary palpi, antennae, legs, thorax and abdomen without long setae. Valvifer (Fig. 17) narrow at base, with both upper and lower margins slightly emarginated in the middle, broader at apex; stylus coniform, with stout and long setae.
Type material. Holotype, male, CHINA: Jinghong (100°47'E, 21°57'N), Yunnan, 4 August 2006, Y.X. Yang coll.. Paratypes: 15 males and 18 females, the same data as the holotype; 1 female, Yunnan Province, Jingdong, E 100°82' N 24°42', 7 August 2006, Y.X. Yang coll.
Type depository. Holotype and 30 paratypes are deposited in the Museum of Hebei University, Baoding, P. R. China; 4 paratypes are preserved in the M.A. Bologna collection, Department of Biology, University Roma Tre, Italy.
Etymology. The specific name is derived from Latin word “s triolatus ”, referring to its longitudinal stripes of elytra.
Distribution. CHINA: Yunnan.
Discussion. This new species is similar to D. venerabilis Kaszab, but differs from the latter by: more parts of body with long black setae, as described above; male antennomere II three times as long as wide, X obviously shorter than III; pronotum longer than wide, hardly depressed at base; median longitudinal light pubescent stripe nearly extending to the apex of elytron, and as broad as that along outer margin.
