Material examined.

Holotype ♀ (SCAU), Shaanxi, Mt. Taibai (34°5'12.41"N, 107°42'41.77"E), 1100 m, 12-13.VII.2012, Na-sen Wei leg., No. SCAU-C0030. Paratype: 1 ♀ (SCAU), Shaanxi, Mt. Taibai (34°5'12.41"N, 107°42'41.77"E), 1100 m, 12-13.VII.2012, Na-sen Wei leg., No. SCAU-C0031.

Diagnosis.

Cleptes niger sp. n. is related to Cleptes albonotatus sp. n., Cleptes flavolineatus sp. n. and Cleptes satoi Tosawa based on the blackish body, coarse punctures on head, rugose pronotum and similar sculptures on the mesopleuron. However, it can be distinguished by the combination of the following characteristics: body without metallic tints or yellow stripes (mesopleuron partly metallic blue in Cleptes satoi , body with yellow stripes in Cleptes flavolineatus sp. n.); metanotum without anteromedian pit (with an anteromedian pit in Cleptes satoi ); dorsal surface of propodeum with six longitudinal ridges and numerous and weak transverse wrinkles (irregularly reticulate with dense wrinkles in Cleptes satoi Tosawa and Cleptes albonotatus sp. n.,); metapleuron polished and weak striate on upper part (entirely and strongly striate in Cleptes albonotatus sp. n. and Cleptes flavolineatus sp. n.).

Description.

Female. Holotype. Body length 7.3 mm (Plate 8A). Forewing length 4.8 mm. HW: HH: HL = 14: 12.5: 8. POL: OOL: OCL = 9: 19: 23. MS = 1.2 MOD. Width of clypeal lower margin = 1.4 ASD. L/W of Ped, F-I, F-II, and F-III are 2.1, 2.4, 1.1, and 0.8, respectively.

Head. Face, ocellar area and vertex with dense and coarse punctures (0-0.5 PD). Frontal sulcus complete, indistinct on lower face (Plate 8B). Clypeus with lower margin convex medially, without acute teeth at corners. Mandibles with sparse punctures and three teeth. Ocellar triangle isosceles, with post-ocellar sulcus indistinct and curvate.

Mesosoma. Pronotum rugose, with coarse and dense punctures. Pronotum with a distinct anterior pit row, without posterior pit row and defined pits, but with shallow depression with irregular punctures along the posterior margin (Plate 8C); without longitudinal median sulcus; with a small depression in the middle of pronotum (Plate 8C). Mesonotum and metanotum with punctures smaller and sparser than on pronotum. Mesoscutum with notauli complete; parapsidal lines incomplete, 1/2 length of notauli; admedian lines absent (Plate 8C). Mesopleuron with dense and coarse punctures and transverse wrinkles; scrobal sulcus short (Plate 8D). Mesoscutellum longitudinally polish in the middle; axillary trough longitudinally striate (Plate 8E). Metanotum without anteromedian pit, with a broad fovea along the posterior margin; axillary trough mostly smooth, longitudinally and weakly striate (Plate 8E). Metapleuron polished and weakly striate on upper part (Plate 8D). Dorsal surface of propodeum with six longitudinal ridges, with numerous and weak transverse wrinkles. Propodeal angles long and blunt (Plate 8E).

Metasoma. T-I nearly impunctate. T-II–T-IV with dense punctures (Plate 8F).

Pubescence. Head with long (1.5-2.0 MOD) and white hairs. Metasoma on T-III and T-IV dorsally and laterally with very long (2.0-2.5 MOD) and brownish hairs.

Colouration. Head and mesosoma entirely black, without metallic reflections. Mandibles testaceous. Antennae blackish-brown, with ventral sides of F-IV to F-XI testaceous. Tegulae black. Legs with coxae and femora blackish-brown, tibiae and tarsi testaceous. Metasoma black, with T-I blackish-brown anteriorly, T-I to T-III with distinct testaceous tint laterally.

Variation. Paratype: Body length 7.1 mm. Forewing length 4.8 mm.

Male. Unknown.

Distribution.

China (Shaanxi).

Biology.

Collected in July at 1100 m.

Etymology.

The specific name refers to the black colouration.

Remarks.

According to Móczár (2000b), Cleptes niger sp. n. belongs to the satoi species-group based on the typical irregular punctures along the posterior margin of pronotum, and black body.
