Material examined.

Holotype ♂ (SCAU), Guizhou, Suiyang, Kuankuoshui National Nature Reserve (28°1'23.16"N, 107°7'45.29"E), 8.VI.2010, Jie Zeng leg., No. SCAU-C0006. Paratype: 1 ♂ (ZJUH), Guizhou, Daozhen, Dashahe, Xiannvdong (29°2'38.19"N, 107°30'31.13"E), 644 m, 24.VIII.2004, Shu-jun Wei leg., No. 20047405.

Diagnosis.

Cleptes villosus sp. n. is similar to Cleptes metallicorpus Ha, Lee & Kim, Cleptes taiwanus Tsuneki, Cleptes thaiensis Tsuneki and Cleptes tibetensis sp. n. based on the mesopleuron with V-shape loop, metanotum with an anteromedian pit and short propodeal angles. However, it can be separated by the combination of the following characteristics: the metallic bluish-green body (purple with greenish golden or blue tints in Cleptes thaiensis ); lower margin of clypeus without acute teeth (present in Cleptes metallicorpus , Cleptes taiwanus and Cleptes tibetensis sp. n.); mandibles without striatopunctures (with distinct striatopunctures in Cleptes metallicorpus ); ocellar triangle equilateral, without post-ocellar sulcus (ocellar triangle isosceles in Cleptes metallicorpus and Cleptes taiwanus , with post-ocellar sulcus in Cleptes taiwanus ); and long, dense hairs on head and mesosoma.

Description.

Male. Holotype. Body length 6.4 mm (Plate 16A). Forewing length 5.0 mm. HW: HH: HL = 21: 13: 8.8. POL: OOL: OCL = 5.5: 7.8: 12. MS = 1 MOD. Width of clypeal lower margin = 1 ASD. L/W of Ped, F-I, F-II, and F-III are 1.6, 1.8, 1.7, and 1.4, respectively.

Head. Face and ocellar area with small, shallow and dense punctures (0.5-1.0 PD). Clypeus with lower margin truncate, without acute teeth at corners. Frontal sulcus complete but weak (Plate 16B). Mandibles with sparse punctures and four teeth. Ocellar triangle equilateral, without post-ocellar sulcus. Vertex with shallower and sparser punctures (1.0-1.5 PD).

Mesosoma. Mesosoma with small and sparse punctures (1.5-3.0 PD). Pronotum with distinct anterior and posterior pit rows (Plate 16C); without longitudinal median sulcus (Plate 16C). Mesoscutum with notauli complete; parapsidal lines nearly complete; admedian lines incomplete, 1/3 length of notauli (Plate 16C); axillary trough smooth. Mesopleuron with foveate V-shape loop (Plate 16D). Metanotum with a small and oval anteromedian pit, with two medially fused foveae along the posterior margin; axillary trough smooth (Plate 16E). Metapleuron mostly smooth and polished (Plate 16D). Dorsal surface of propodeum irregularly reticulate. Propodeal angles short and blunt (Plate 16E).

Metasoma. Posterior margin of each segment of metasoma impunctate. T-I and T-V nearly impunctate. T-II with small and dense punctures, only scattered on anterior 2/3 (Plate 16F). T-III with punctures twice as dense as on T-II, with very small dots in intervals between the larger punctures. T-IV with punctures on slightly sparser than on T-III.

Pubescence. Head with long (1.5 MOD), dense and white hairs. Mesosoma with long (1.5-2.0 MOD), dense and whitish hairs. Metasoma laterally on T-I and T-II and on T-III with long (1.5-2.0 MOD), sparse and white hairs; T-IV with short (0.5-0.8 MOD) and sparse hairs; T-V with only few short (0.5-0.8 MOD) hairs.

Colouration. Body mostly metallic bluish-green, with vertex mostly purple and with metallic blue tints. Mandibles metallic bluish-green, with teeth blackish-brown. Antennae black, with scapes and pedicels metallic bluish-green. Tegulae metallic bluish-green. Legs metallic bluish-green, with tibiae and tarsi testaceous. Metasoma purple, with metallic blue tints, posterior margin of each segment black, T-V blackish-blue.

Variation. Paratype.Body length 5.7 mm. Forewing length 4.7 mm. Clypeus covered with sparser and shorter setae.

Female. Unknown.

Distribution.

Oriental part of China (Guizhou).

Biology.

Collected in June and August.

Etymology.

The specific name refers to the whitish, dense relatively long hairs on the head and mesosoma.

Remarks.

According to Móczár (2000a), Cleptes villosus sp. n. belongs to the asianus species-group based on the two pit rows on pronotum, longitudinal median sulcus absent, and mesopleuron with V-shape loop.
