Cleptes tibetensis sp. n. Plate 14

Material examined.

Holotype ♂ (SCAU), Tibet, Pailongxiang, Daxiagu (30°1'10.56"N, 94°59'49.92"E), 2054 m, 15.VI.2009, Mei-cai Wei leg., No. SCAU-C0003.

Diagnosis.

Cleptes tibetensis sp. n. is similar to Cleptes crassiceps Tsuneki, Cleptes metallicorpus Ha, Lee & Kim, and Cleptes villosus sp. n. based on the posterior pit row on pronotum, V-shape loop on mesopleuron, and short propodeal angles. However, it can be distinguished by the combination of the following characteristics: metallic bluish-purple metasoma (metasoma black, only partly with metallic reflections in Cleptes crassiceps ); absence of frontal sulcus (present in Cleptes crassiceps , Cleptes metallicorpus and Cleptes villosus sp. n.); lower margin of clypeus with acute teeth at corners (absent in Cleptes crassiceps and Cleptes villosus sp. n.); mandibles without striatopunctures (with striatopunctures in Cleptes metallicorpus ); metanotum with transverse depression anteriorly (absent in Cleptes crassiceps , Cleptes metallicorpus , and Cleptes villosus sp. n.); metanotum with a broad fovea along the posterior margin (with two foveae along the posterior margin in Cleptes metallicorpus ).

Description.

Male. Holotype. Body length 6.7 mm (Plate 14A). Forewing length 5.6 mm. HW: HH: HL = 18.8: 12.5: 10.5. POL: OOL: OCL = 5: 9.8: 12.3. MS = 0.9 MOD. Width of clypeal lower margin = 1 ASD. L/W of Ped, F-I, F-II, and F-III are 1.5, 2.1, 1.7, and 1.7, respectively.

Head. Face, ocellar area and vertex with small and sparse punctures (1-5 PD). Clypeus with lower margin slightly convex medially, with acute teeth at corners. Frontal sulcus absent (Plate 14B). Mandibles with sparse punctures. Ocellar triangle equilateral, without post-ocellar sulcus.

Mesosoma. Mesosoma with punctures similar to those on vertex. Pronotum with distinct anterior and posterior pit rows (Plate 14C); without longitudinal median sulcus (Plate 14C). Mesoscutum with notauli complete; parapsidal lines nearly complete; admedian lines incomplete, 1/6 length of notauli (Plate 14C); axillary trough smooth. Mesopleuron with distinct V-shape loop (Plate 14D). Metanotum with transverse depression anteriorly, with a small and oval anteromedian pit; with a broad fovea along the posterior margin; axillary trough smooth and polished (Plate 14E). Metapleuron polished, with some indistinct transverse wrinkles on upper part (Plate 14D). Dorsal surface of propodeum with irregular ridges; lateral margins parallel. Propodeal angles short and stumpy (Plate 14E).

Metasoma. T-I and T-V impunctate. T-II–T-IV with dense punctures (Plate 14F). Punctures on T-III denser than those on T-II and T-IV.

Pubescence. Head with long (1.0-1.3 MOD), sparse and whitish hairs. Metasoma laterally and on T-III and T-IV also dorsally with long (1.5-2.0 MOD) and whitish hairs.

Colouration. Face and clypeus yellowish-green. Vertex metallic green, with purple tints. Mandibles metallic green, with teeth blackish-brown. Antennae blackish-brown, with scapes and pedicels metallic green. Mesosoma mostly metallic green, with some purple tints. Tegulae metallic green. Legs metallic green, with tarsi testaceous. Metasoma metallic bluish-purple, with T-I yellowish-green tints anteriorly, with T-I bluish-green tints laterally; T-V black.

Female. Unknown.

Distribution.

China (Tibet).

Biology.

Collected in June at 2054 m.

Etymology.

The species is named after the type locality.

Remarks.

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