Cleptes helanshanus sp. n. Plate 4

Material examined.

Holotype ♀ (SCAU), Inner Mongolia, Mt. Helan (39°2'5.27"N, 106°1'38.09"E), 27.VII.2010, Hong-fei Chai leg., No. SCAU-C0002.

Diagnosis.

This species resembles Cleptes mareki Rosa based on the pronotum without posterior pit row and metanotum without pit or fovea. However, Cleptes helanshanus sp. n. can be quickly separated from this species by the colouration: pronotum golden, laterally with green tints, mesopleuron and metanotum golden red, and mesoscutellum greenish-golden.

Description.

Female. Holotype. Body length 5.9 mm (Plate 4A). Forewing length 3.9 mm. HW: HH: HL = 79: 81: 38. POL: OOL: OCL = 10: 13: 18. MS = 1.7 MOD. Width of clypeal lower margin = 1.7 ASD. L/W of Ped, F-I, F-II, and F-III are 2.1, 2.1, 1.2, and 1.0, respectively.

Head. Face with small, shallow and sparse punctures (1-4 PD). Clypeus with lower margin truncate, without acute teeth at corners. Frontal sulcus complete, even if somewhat indistinct towards the clypeus (Plate 4B). Mandibles with sparse punctures and four teeth. Ocellar area and vertex with slightly denser punctures (1-3 PD). Ocellar triangle isosceles, without post-ocellar sulcus.

Mesosoma. Pronotum with small and sparse punctures similar to those on vertex; anterior pit row somewhat interrupted medially, without posterior pit row (Plate 4C); without longitudinal median sulcus (Plate 4C). Mesonotum and metanotum almost impunctate, with very sparse and shallow punctures. Mesoscutum with notauli complete; parapsidal lines incomplete, 3/4 length of notauli; admedian lines absent (Plate 4C); axillary trough indistinctly and longitudinally striate. Mesopleuron somewhat polished, with scrobal sulcus, and with sparse punctures on anterior half (Plate 4D). Transverse narrow sulcus present between mesoscutellum and metanotum (Plate 4E). Metanotum without pit or fovea; axillary trough weakly and irregularly reticulate (Plate 4E). Metapleuron polished, with some weak and transverse wrinkles on the upper part (Plate 4D). Dorsal surface of propodeum irregularly reticulate, with lateral margin straight and parallel. Propodeal angles short and stumpy (Plate 4E).

Metasoma. T-I with small and sparse punctures. T-II and T-III with dense punctures. T-IV with anterior half impunctate, and posterior half with sparse punctures (Plate 4F).

Pubescence. Head with long (2 MOD) and erect black bristles on vertex. Metasoma on T-III and T-IV dorsally and laterally with long (1.5 MOD) and white hairs; with very long (3-4 MOD) and erect black bristles laterally on T-III and T-IV.

Colouration. Head black, without metallic reflections. Mandibles blackish-brown, with teeth testaceous. Antennae black, with testaceous between pedicel and F-I. Pronotum golden, with green tints on lateral sides. Mesopleuron and metanotum golden-red. Mesoscutum black. Mesoscutellum greenish-golden. Metapleuron, propodeum and tegulae black. Legs blackish-brown, with tibiae and tarsi testaceous. Metasoma blackish-brown, with posterior margins of all segments testaceous, with small pale spot present between T-III and T-IV.

Male. Unknown.

Distribution.

Palaearctic part of China (Inner Mongolia).

Biology.

Collected in July.

Etymology.

The species is named after the type locality.

Remarks.

According to Móczár (1997b), Cleptes helanshanus 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.
