Description. Male. Holotype (Fig. 1 e). Length 13 mm. Head brown (Figs 4 a–b), palpi of mouthparts, labrum and malar space yellowish brown, narrow posterior margin of clypeus, supraclypeal area, frons, lower 0.7 of inner orbit, ocellar area, anterior margin and middle stripe of postocellar area and posterior side of head largely black; basal two antennomeres entirely, basal 0.25 of antennomere 3 yellow brown, apical 0.75 of antennomere 3 and other antennomeres dark brown (Fig. 11 d). Thorax black, broad posterior margin of pronotum, tegula, lateral stripe on mesoscutal middle lobe, broad anterior margin and narrow posterior margin of parapsis, mesoscutellum (excluding appendage), metascutellum, cenchrus and upper margin of metapleuron pale brown. Abdomen brown to pale brown, tergite 2 and subgenital plate largely and harpes entirely yellow brown, basal 0.8 (middle) to 0.6 (lateral sides) of tergite 1, short lateral macula and narrow anterior margin of tergite 2 (Fig. 6 d), basal 0.3 of tergites 3–7 blackish brown, base of basal sternites more or less blackish brown. Body hairs brown to pale brown. Legs black, hind trochanter, broad anterior stripe and broad apex of fore and middle femora, fore and middle tibiae entirely pale brown, hind tibia brown to dark brown, all tarsi yellow brown. Wings yellowish infuscate in anterior part and gradually paler toward posterior margin, vein C and pterostigma pale brown, posterior of vein Sc+R and most of vein M+Cu blackish; hind wing weakly infuscate, slightly paler than forewing.
Punctures on labrum small and dense, narrow interspaces between punctures weakly microsculptured; punctures on clypeus dense and large, interspaces between punctures almost smooth, shiny (Fig. 4 b); inner orbit and hind orbit densely punctured, interspaces linear, weakly microsculptured, less shiny; frons densely and coarsely punctured, interspaces narrow, hardly microsculptured, more or less shiny; punctures on temple and postocellar area slightly sparser than frons, surface very weakly microsculptured, moderately shiny (Fig. 4 a–c); malar space densely punctured, shiny; upper corner of pronotum moderately punctured and shiny, depressed part of pronotum coarsely punctured and microsculptured, feebly shiny; mesoscutal middle lobe and lateral lobe densely punctured, interspaces very narrow, distinctly microsculptured, almost dim; mesoscutellum densely punctured with narrow smooth interspaces, less shiny; mesoscutellar appendage polished, impunctate, strongly shiny; parapsis weakly microsculptured, less shiny; metapostnotum densely microsculptured (Fig. 6 d); punctures on upper half of mesepisternum large and very dense, interspaces very narrow, hardly shiny; punctures on lower half of mesepisternum smaller and much sparse, surface indistinctly microsculptured, shiny; mesepimeron and metapleuron strongly microsculptured mixed with some large but shallow punctures; abdominal tergite 1 densely microsculptured, almost mat, narrow lateral side densely punctured, very narrow posterior margin weakly coriaceous, less shiny; tergite 2 hardly punctured, densely microsculptured, other tergites strongly microsculptured mixed with dense but indistinct punctures in entire length, mat (Fig. 6 d); microsculpture on median part of tergite 8–9 hardly weaker than lateral part; sternites densely punctured except for apical half of subgenital plate.
Hairs on dorsum of head and mesopleuron dense and almost straight, about 0.9 times as long as diameter of median ocellus (Fig. 4 a–b); hairs on mesonotum dense and about 0.6 times as long as diameter of median ocellus; dorsum of abdominal tergites 1–2 largely glabrous except for narrow middle stripe, other tergites densely pubescent; mesoscutellar appendage and intertergites of abdomen glabrous (Fig. 6 d).
Labrum broad, anterior margin round, not acute; anterior margin of clypeus weakly incised in entire length, almost truncate; malar space about as long as radius of median ocellus (Fig. 4 b); hind orbit round, without occipital carina; distance between eyes at level of anterior tentorial pits 1.2 times as long as longest axis of eye (Fig. 4 b); mandibles as Figs 11 m–n; middle fovea roundish, shallow, closed; lateral fovea small; frons small, roundish, frontal ridge obtuse; POL: OOL: OCL=15: 40: 35; interocellar furrow narrow and very deep, postocellar furrow fine and shallow, hardly bent forward; postocellar area flat, hardly elevated, about 1.3 times as broad as long; lateral furrow broad but very shallow, weakly curved, weakly divergent backwards; head hardly dilated behind eyes in dorsal view (Fig. 4 a). Antenna as long as thorax, antennomere 3 almost 1.3 times as long as antennomeres 4 and 5 together and 1.2 times as long as antennomeres 6–9 together, antennomere 7 about 0.9 times as long as broad (Fig. 11 d). Mesoscutal middle lobe with narrow but distinct middle furrow; mesoscutellum roundly elevated, anterior margin weakly and roundly protruding, transverse anterior furrow deep; mesoscutellar appendage short with middle length about as long as diameter of median ocellus; cenchrus transverse, much broader than long, CD=1.7 (Fig. 6 d); mesepisternum roundly and weakly elevated at middle, without blunt ridge.

Other specimen. 1Ƌ, CHINA: SHAANXI: Kaitianguan, Mt. Taibaishan, Qinling Mts., 34°00'N, 107°51'E, 2000m, 1. VI. 2005, A. Shinohara. (NSMT).
Distribution. China (Shaanxi, Henan). The species is recorded from Shaanxi for the first time (Fig. 12).
Host plant. Unknown.
Remarks. As Curvatapenis merged with Neocolochelyna, Curvatapenis testaceous is transferred into Neocolochelyna. N. testaceoa is similar to N. itoi Takeuchi from Japan. See the above key for the differences between the two species.
