Pseudopraon hei Tian & Chen sp. n. Figure 3
Female. Body length 2.0 mm, fore wing length 1.8 mm.
Head. Head transverse in dorsal view, slightly wider than mesoscutum, smooth and shiny, with sparsely long setae (Figure 3B). Eyes medium-sized, oval, sparsely setose (Figure 3A). Temple in dorsal view 0.85 times as long as eye. Malar space equal to 0.2 × longitudinal diameter of eye. POL 1.4 × Od. Width of face 1.25 × its height and 0.4 × width of head. Face with dense setae. Clypeus oval, raised with several long setae, tentoriocular line equal to 0.25 of intertentorial line. Maxillary palp 4-segmented, labial palp 2-segmented (Figure 3A). Antenna filiform, with 18 segments. F1 approx. 1.2 times longer than F2. F1 4.0 × as long as wide, F2 3.1 × as long as wide (Figure 3H).
Mesosoma. Mesonotum with central and lateral lobes densely pubescent. Notauli deep and distinct throughout (Figure 3C). Propodeum glabrous, with dense long setae (Figure 3D).
Wings. Fore wing: apical margin with long setae, which are longer than setae on wing membrane. Pterostigma triangular, 3.4 × as long as wide. Distal abscissa of 1-R1 (= metacarp) 0.7 × as long as the length of pterostigma. Vein r+3-SR (= radial vein) slightly longer than the width of pterostigma, shorter than 1-R1 (5:7), do not reach the wing apex. 1-SR+M totally absent. Vein m-cu+2-M feebly pigmented, but distinctly present (Figure 3G). Hind wing with a complete cell, apical margin with long setae, which are longer than setae on wing membrane.
Metasoma. T1 nearly smooth, 1.2 × longer than width at spiracle level, with long setae close to lateral corners. Ovipositor sheath with some long setae and its apex obtuse (Figure 3J).
Colour. Head dark brown, face somewhat paler, clypeus and mandibles yellowish to light brown. Maxillary and labial palpi white to yellowish. Antennal scape, pedicel and F1 yellowish. Remainder of antenna and mesoscutum dark brown. Wings hyaline with brown venation. Legs yellowish to light brown, apices of tarsi dark. Metasoma and ovipositor sheath dark brown to brown.
Holotype: ♀, S China, Yunnan, Kunming, 30.III.1981, He Jun-Hua, No.811140.
This species is the second known species of this genus and can be easily differentiated from the type species, P. mindariphagum Starý, 1975 by having the flagellomere of antenna with more segments and the apex of ovipositor sheath sparsely setose (versus densely pubescent).
The new species is named in honour of Prof. Jun-Hua He (ZJUH), who also collected the holotype, for his valuable contribution to the taxonomy of parasitoid wasps in China.
