Diagnosis.

Posterior pit row of pronotum with two median pits considerably larger than the others. Pronotum with longitudinal median sulcus incomplete, and somewhat foveate. Mesopleuron with strong foveate V-shape loop. Metanotum with a big, deep and triangular anteromedian pit, with two foveae along the posterior margin.

Description.

Redescribed after a female from Hunan (Liuyang City). Body length 8.2 mm (Plate 12A). Forewing length 5.0 mm. HW: HH: HL = 37.5: 30.5: 19. POL: OOL: OCL = 16: 16: 27.5. MS = 1.4 MOD. Width of clypeal lower margin = 1 ASD. L/W of Ped, F-I, F-II, and F-III are 2.0, 2.0, 0.9, and 1.0, respectively.

Head. Face with dense and coarse punctures (0-0.5 PD) merging laterally, with big polish area above clypeus. Clypeus with lower margin slightly convex medially, with distinct acute teeth at corners. Frontal sulcus complete, but becoming shallow and indistinct on upper 1/3, after reaching pit before midocellus (Plate 12B). Mandibles with sparse punctures and three teeth. Ocellar area and vertex with shallower and sparser punctures (0.5-1 PD). Ocellar triangle isosceles, without post-ocellar sulcus.

Mesosoma. Mesosoma with small and shallow punctures, and gradually sparser from pronotum to metanotum. Pronotum with distinct anterior and posterior pit rows, with two median pits of posterior pit row considerably larger than the others (Plate 12C); longitudinal median sulcus incomplete, and somewhat foveate. Mesoscutum with notauli complete; parapsidal lines nearly complete; admedian lines incomplete, 1/8 length of notauli (Plate 12C); axillary trough longitudinally striate. Mesopleuron with strong foveate V-shape loop (Plate 12D). A transverse foveate sulcus present between mesoscutellum and metanotum (Plate 12E). Metanotum with a big, deep and triangular anteromedian pit, with two foveae along the posterior margin; axillary trough with several oblique wrinkles (Plate 12E). Metapleuron polished, with big and triangular pit on upper part (Plate 12D). Dorsal surface of propodeum rectangular, with width longer than length (L: W = 1: 3), reticulate, with aligned areolae along the anterior and lateral margins. Propodeal angles big and blunt produced obliquely (Plate 12E).

Metasoma. T-I with small and sparse punctures. T-II–T-IV with bigger and denser punctures (Plate 12F). Punctures on T-IV double than those on T-II and T-III, with bigger punctures deeply incised. T-IV with apex medially incised.

Pubescence. Head with short (0.5-1.0 MOD), sparse and brownish hairs, scattered on clypeus and posterior half of vertex. Metasoma nearly without hairs dorsally, with only few very short (0.5 MOD) hairs laterally.

Colouration. Head and mesosoma metallic blue, with purple reflections. Mandibles testaceous, with teeth blackish-brown. Antennae black, with scapes and pedicels metallic blue, ventral sides of F-IV to F-XI testaceous. Tegulae metallic blue, with brown tint. Legs metallic blue, with ventral side of tibiae and tarsi brown. Metasoma metallic bluish-purple.

Male. Body length 6.1-6.7 mm (Plate 13A). Forewing length 3.6-4.3 mm. Differing from female as follows: pronotum with longitudinal median sulcus deeper (Plate 13C); posterior pit row less distinct, with median pair of pits bigger than the others (Plate 13C); body largely purple with metallic blue reflections (Plate 13B, 13 D–F).

Variation. Females. Body length 5.8-8.2 mm. Forewing length 3.6-5.0 mm. Clypeus almost truncate medially, with distinct acute teeth at corners. Males. Body length 6.1-6.7 mm. Forewing length: 3.6-4.3 mm. Body largely purple with metallic blue reflections.

Distribution.

China (Jiangsu, Anhui, Zhejiang, Taiwan, Hunan, Guangdong, Yunnan); Korea.

Biology.

Parasitoid of Diprionidae . Collected from May, June, August and October at 1548 m to 1959 m.

Remarks.

Cleptes sjostedti Hammer belongs to the fudzi species-group ( Móczár 1998a). The correct writing of the name is sjostedti and not sjoestedti as reported in Móczár (1998a). The species was dedicated to Yngve Sjöstedt, former director of the Naturhistoriska Riksmuseum in Stockholm. According to the ICZN (Art. 32.5.2.1) only in the case of a German name would the correct form be sjoestedti.
