description: Oxyporus (Oxyporus) wangae sp. nov. (Figs. 1 A–B, Figs. 2 A–E)
Type material. Holotype: CHINA: Yunnan Province.: ♂, Mojiang County, Tuan tian village, alt. 1857m, 23°36′N, 101°17′E, 23–31-July-2016, Wang Chun-mei leg. Paratypes: CHINA: Yunnan Province: 1♂, same data as the Holotype (YFTC).
Description. BL: 10.18 mm, FBL: 3.18 mm, ML: 1.64 mm, HL: 1.64 mm, HW: 2.22 mm, TL: 0.84 mm, AL: 1.71 mm, LW: 0.83 mm, PL: 1.50 mm, PW: 1.98 mm, ELL: 2.05 mm, ELW: 2.83 mm, EYL: 0.78 mm. Body moderately stout, surface almost smooth and glossy. Color reddish yellow, with mandibles, head, pronotum, scutellum, abdomen (except segments 3–4 and sides of segments 5–6) black, each elytra bearing subtriangular black marking at outer apical angle extending from the posterior 1/2 of lateral margin to middle of posterior margin and ending near suture by narrow black fascia along posterior margin.. (Figs. 1 A).
Male: Head oval, wider than long (ratio 1.35), broader than pronotum (ratio 1.12), slightly widened posteriad behind eyes, posterior angles obtuse. Mandibles as long as head, moderately broad, inner edges evenly curved to acute apices. Labrum broadly and deeply emarginate at middle. Clypeus broadly and shallowly emarginate at middle. Maxillary palpi with first segment shortest, second longer than third, third slightly wider than last and almost equal in length, and apical segment of labial palpi slightly wider than length of an eye (ratio 1.06). Frons broadly, shallowly bi-impressed between antennal insertions; Antennae slightly longer than head (ratio 1.04); segments 1–4 elongate, 5–10 transverse, slightly asymmetrical and flattened, apical segment narrower than preceding segment, each segment with long setae near apex, and segments 5–10 glabrous medially and covered with fine setae laterally, the relative length of segments from base to apex as 0.25: 0.13: 0.18: 0.15: 0.14: 0.15: 0.13: 0.14: 0.14: 0.13: 0.20. Eyes large and convex. Vertex nearly smooth, two setiferous punctures near inner margin of eye, one anteriad and one posteriad. Temples slightly longer than eyes seen from above (ratio 1.08).
Pronotum subhexagonal, slightly transverse, wider than long (ratio 1.35), shorter (ratio 0.73) and narrower (ratio 0.70) than elytra, lateral margins arcuate at about anterior 1/3 and subarcuately narrowed posteriad, widest at about anterior 1/3; disc almost impunctate, devoid of microsculpture, with 1 deep, transverse depression located just before middle, which is widened to both sides, and additionaly, surface bearing 2 vague longitudinal depressions in middle just behind the transverse depression, which does not reach to posterior margin, and each lateral side with 1 fovea in the middle; 8 setiferous punctures bearing at anterior margin, 4 ones at each lateral margin. Scutellum impunctate, rounded at apex, surface almost smooth.
Elytra wider than long (ratio 1.38), slightly widened apicad; each elytron with 1 row of evenly spaced small punctures along suture, 2 longitudinal rows of coarse variably spaced punctures medially, and several, scattered coarse punctures to either side of rows; apical, lateral, and posterior margins bearing a few short setae; humeri produced forward and convex above. Hind Wings developed.
Abdomen with tergites 3–4 each with a pair of pruinose spots at middle and tergites 3–6 each with 1–3 irregular setiferous punctures along lateral margin; punctation of tergites very sparse and vague, surface between punctures with exceedingly fine and dense microsculpture of transverse striae; posterior margins of sternites 7 slightly and broadly emarginated at middle but posterior margins of sternites 8 strongly and broadly emarginated at middle. (Fig. 1 B)
Aedeagus slightly asymmetrical and moderately sclerotized; median lobe somewhat widened apicad and slightly narrowed in middle, with apical margin rounded; parameres relatively long and slender, gradually narrowed apicad, (Figs. 2 A–C); the right lobe and left lobe without minute seta at each apex. (Figs. 2 D–E)
Female: Unknown.
Remarks. Oxyporus wangae n. sp. is similar to O. germanus Sharp from Lijiang City (Yulongxueshan Natural Reserve), Yunnan Province, China, in the color of the body, but can be distinguished from the latter by the following characters (see key below): elytra without a slightly broad black fascia along full length of suture; apical portion of abdominal tergite 8 orange yellow; right and left paramere without minute seta at each apex.
Etymology. The specific epithet is patronymic in honor of the collector of the Holotype, WANG Chun-Mei.
Habitat and distribution. The new species was found in fungi. It is at present only known from the type locality in southwest Yunnan Province, China.
