This new species is similar to the female of C. ( P. ) pellucens ( Nees, 1816 ) , because both have metasomal carapace widest at middle and apically slightly narrowed ( Fig. 94E ), but can be separated by the following characters: scutellum densely punctulate ( Fig. 94C ) ( versus smooth in C. ( P. ) pellucens ); hind femur 3.4 × longer than wide ( versus 2.6 × width) and carapace with yellowish irregular-edged band in basal 1/4, and its corners light ( Fig. 94E ) ( versus usually black, sometimes with pair of large reddish or yellowish latero-basal spots). Description. Holotype , female, length of body 5.0 mm, of fore wing 3.4 mm . Head. Head transverse, width of head 1.9 × its dorsal length; occiput hardly excavated; antennomeres 27, antenna slightly widened medially, length of 3 rd and penultimate antennomeres 3.8 × and 1.5 × their width, respectively ( Fig. 94H ); eye 1.4 × as long as temple in dorsal view; OOL: OD: POL=19: 5: 12; temple narrowed to parallel-sided behind eyes; frons and vertex striate-rugose ( Fig. 94G ); face flat, irregular punctate-rugose, width of face 1.8 × its height; eyes about parallel; clypeus densely punctulate, interspaces shiny, 1.5 × wider than high, distance between tentorial pits 1.2 × distance between pits and eyes ( Fig. 94F ).

FIGURE 95. Chelonus ( Parachelonus ) hirsutus sp. nov. , male, paratype, habitus, lateral aspect. Mesosoma. Length of mesosoma 1.5 × its height in lateral view; side of pronotum reticulate-rugose, mesopleuron densely setose ( Fig. 94B ); notauli slightly distinct; anterior sclerite of mesoscutum dense punctulate and posterior part of mesoscutum coarsely reticulate-rugose, scutellum slightly convex, punctate and shiny; scutellar suture comparatively deep and with carinae; propodeum coarsely rugose, tubercles distinct ( Fig. 94C ). Wings . Vein r somewhat arched; marginal cell 0.9 × as long as pterostigma; pterostigma 3.4 × longer than wide; r: 3-SR: SR1=9: 12: 40; SR1 curved towards pterostigma; marginal cell 1.4 × longer than second submarginal cell; 1-CU1: 2-CU1=15: 26; 2-R1 short ( Fig. 94A ). Legs. Hind coxa punctate laterally and densely setose; length of hind femur, tibia and basitarsus 2.2 ×, 5.8 × and 5.8 × their maximum width, respectively; length of inner hind tibial spur 0.5 × hind basitarsus. Metasoma. Length of carapace 2.0 × its maximum width, widest at middle, apically slightly narrowed; basal 0.7 of carapace reticulate-rugose and coriaceous apically ( Fig. 94E ); carapace in lateral view 2.9 × longer than high, posterior height of metasoma 1.8 × its anterior height, carapace apically slightly incurved ( Fig. 94D ). Colour. Black; antenna brown; mandible light brown; palpi light brown; pterostigma brown; middle of wing and its veins medium light brown, wing base and its veins light yellowish; carapace with yellowish irregular-edged band in basal 1/4, and its corners light. Male. Antennomeres 30, antenna filiform, not widened medially ( Fig. 96I ); carapace apically distinctly incurved ( Fig. 96D ); apical aperture in posterior view medium-sized, oval and median process of aperture horizontal, nearly round ( Fig. 96F ); carapace with 2 large spots in basal 1/3; other characters as in female ( Fig. 95 ). Biology. Unknown. Distribution. China ( Guizhou , Liaoning ). Etymology. Named after its densely setose mesopleuron, “ hirsutus ” is Latin for bristly, hairy.
