Figs 69–70 Material examined. Holotype : female, Gutian Mt. , Zhejiang Prov. , China , 22.VII.1986 , Xiaoming Lou, No. 863205 ( ZJUH ). Diagnosis. The new species is similar to C. ( M. ) elaeaphilus ( Silvestri, 1908 ) sharing the metasoma posteriorly slightly declivous in lateral view ( Fig. 70D ), widest at middle in dorsal view ( Fig. 70E ), and eye almost as long as temples, temples parallel-sided to widened in dorsal view ( Fig. 70G ), but the two species can be separated by the following characters: body entirely reddish brown and carapace with yellowish irregular edge band in basal third ( Fig. 69 ) ( versus body black and carapace with one large medial yellowish spot in C. ( M. ) elaeaphilus ); antenna of female as long as head, mesosoma and 0.5 metasoma combined ( Fig. 70H ) ( versus as long as head and mesosoma combined); mesosoma medium-sized, its length 1.5 × its height ( Fig. 70B ) ( versus short, 1.25 × its height). FIGURE 69. Chelonus ( Microchelonus ) ruficorpus sp. nov. , female, paratype, habitus, lateral aspect. Description. Holotype , female, length of body 2.7 mm , of fore wing 2.6 mm . Head. Head transverse, width of head 2.1 × its dorsal length; occiput slightly excavated; antennomeres 16, antenna filiform, not widened; length of 3 rd and penultimate antennomeres 4.0 × and 2.0 × their width, respectively ( Fig. 70H ); eye 1.1 × longer than temple in dorsal view; OOL: OD: POL= 21: 6: 11; temple parallel-sided behind eyes; frons and vertex striate-rugose ( Fig. 70G ); face flat, longitudinally punctate-rugose, width of face 2.0 × its height; eyes slightly converging; clypeus very transverse, sparsely punctulate, shiny, 2.2 × wider than high; distance between tentorial pits 1.6 × distance between pits and eyes ( Fig. 70F ). Mesosoma. Length of mesosoma 1.5 × its height; side of pronotum finely punctate, mesopleuron densely setose ( Fig. 70B ); scutellum rather flat, smooth medially, punctate laterally; scutellar suture comparatively deep, narrow, with carinae; propodeum coarsely rugose, lateral tubercles weak and small ( Fig. 70C ). Wings. Vein r straight; marginal cell 0.9 × as long as pterostigma, pterostigma 2.4 × longer than wide; r: 3-SR: SR1=10: 9: 42; SR1 slightly sinuate; marginal cell 2.0 × longer than second submarginal cell; 1-CU1: 2-CU1=7: 16, 2-R1 absent ( Fig. 70A ).

A , fore wing; B , mesosoma, lateral aspect; C , mesosoma, dorsal aspect; D , metasoma, lateral aspect; E , metasoma, dorsal aspect; F , head, anterior aspect; G , head, dorsal aspect; H , antenna; I , head, lateral aspect. Legs. Hind coxa punctate and shiny laterally; length of hind femur, tibia and basitarsus 3.5 ×, 4.9 × and 4.4 × their maximum width, respectively; length of inner hind tibial spur 0.5 × hind basitarsus. Metasoma. Length of carapace 1.8 × its maximum width in dorsal view, widest after middle, apically rounded; carapace striate-rugose up to basal 60% and posteriorly punctate ( Fig. 70E ); carapace in lateral view 3.2 × longer than high, posteriorly rather truncate and declivous; carapace evenly widened; posterior height of carapace 1.9 × its anterior height; apex of metasomal carapace slightly incurved and ventral opening of carapace 0.9 × as long as carapace ( Fig. 70D ). Colour. Body reddish brown; antenna light brown; palpi reddish brown; pterostigma light brown; parastigma yellowish; wing and its veins light brown; legs almost entirely yellowish brown; carapace with yellowish irregular edge band in basal 1/3, and latero-basally light. Male. Unknown. Biology. Unknown. Distribution. China ( Zhejiang ). Etymology. Named after the reddish-brown body: “ corpus ” is Latin for body, flesh and “ rufus ” is Latin for red, reddish.
