Diagnosis.

Cleptes sinensis sp. n. shares the metallic blue colouration on head and part of mesosoma, pronotum without posterior pit row, and polished mesopleuron with Cleptes nitidulus (Fabricius) and Cleptes mareki Rosa. However, it can be distinguished by metasoma blackish-brown (T-I and T-II testaceous in Cleptes nitidulus and black with weak blue reflections in Cleptes mareki ); metanotum with a broad fovea along the posterior margin (without broad fovea in Cleptes nitidulus and Cleptes mareki ); dorsal surface of propodeum with six longitudinal ridges and numerous and weak transverse wrinkles (irregularly reticulate in Cleptes nitidulus and Cleptes mareki ).

Description.

Male. Holotype. Body length 6.2 mm (Plate 11A). Forewing length 4.9 mm. HW: HH: HL = 13: 10: 7.5. POL: OOL: OCL = 8.5: 15.5: 15. MS = 0.6 MOD. Width of clypeal lower margin = 1.3 ASD. L/W of Ped, F-I, F-II, and F-III are 2.1, 3.2, 2.1, and 2.1, respectively.

Head. Face with dense and coarse punctures (0-0.5 PD). Clypeus with lower margin indistinctly convex medially, without acute teeth at corners. Frontal sulcus complete (Plate 11B). Mandibles mostly polished, with few punctures and three teeth. Ocellar area with sparser punctures (0.5 PD) than those on face. Ocellar triangle isosceles, with post-ocellar sulcus. Vertex with punctures shallower and sparser (0.5-1.0 PD).

Mesosoma. Punctures small, shallow and sparse (0.5-1.5 PD) on pronotum, and even sparser on mesonotum and metanotum. Pronotum with a distinct anterior pit row, without posterior pit row (Plate 11C); without longitudinal median sulcus, with shallow depression in the middle of pronotum (Plate 11C). Mesoscutum with notauli complete; parapsidal lines incomplete, 3/4 length of notauli; admedian lines incomplete, 1/3 length of notauli (Plate 11C); axillary trough longitudinally striate. Mesopleuron polished, with short scrobal sulcus and sparse punctures (Plate 11D). Metanotum without anteromedian pit, with a broad fovea along the posterior margin; axillary trough polished (Plate 11E). Metapleuron smooth and polished (Plate 11D). Dorsal surface of propodeum with six longitudinal ridges, with numerous and weak transverse wrinkles. Propodeal angles long and blunt (Plate 11E).

Metasoma. T-I nearly impunctate. T-II–T-IV with small and dense punctures. Punctures on T-III denser than those on T-II and T-IV. T-V with posterior margin emarginate medially (Plate 11F).

Pubescence. Head on clypeus with short (0.5-1.0 MOD), sparse and white hairs; on vertex nearly without hairs. Metasoma nearly without hairs, only with few on T-IV and T-V laterally.

Colouration. Head metallic blue. Mandibles blackish-brown, with testaceous in the middle. Antennae blackish-brown, with pedicels brown. Mesosoma metallic blue, with propodeum, mesopleuron and metapleuron black. Tegulae brown. Legs blackish-brown, with tarsi testaceous. Mesopleuron, metapleuron and propodeum black. Metasoma blackish-brown, with T-I anteriorly and all segments laterally and along the posterior margin testaceous.

Variation. Body length 4.3-6.6 mm. Forewing length 3.9-5.3 mm. Vertex metallic blue, with some purple tints. Mesonotum and metanotum metallic blue, with more or less blackish-brown tints. One specimen from Hainan with blackish-brown mesosoma, and indistinct metallic blue reflections. Pronotum with irregular and shallow punctures along the posterior margin. Metasoma with few 1.5-2.0 MOD long and sparse hairs on T-I, T-II, and T-III laterally.

Female. Unknown.

Distribution.

China (Shaanxi, Zhejiang, Hubei, Hainan, Sichuan).

Biology.

Collected from May, July and August at 1344 m to 1632 m.

Remarks.

According to Móczár (1997b), Cleptes sinensis sp. n. belongs to the nitidulus species-group based on the pronotum without posterior pit row and longitudinal median sulcus, and the blackish-brown metasoma.
