本文描述了在湖北省神农架林区采到的微蛛亚科瘤胸蛛属(Oedothorax)二新种:裂缝瘤胸蛛,新种Oedothorax rimatus sp.nov.和穿孔瘤胸蛛,新种Oedothorax foratus sp.nov.。模式标本均保存于白求恩医科大学生物教研室。
In the present paper two new species of the genus Oedothorax are described. All types are deposited in the Department of Biology, Norman Bethune University of Medical Sciences.1. Oedothorax rimatus sp. nov. (fig. 1-7)Holotype ♂, allotype ♀, paratypes 10 ♀♀ 13 ♂♂, collected from Shennongjia Forest Region (31°15’-31°57’N, 109°56’-110°58’E), Hubei Province, June-August, 1985.Body length ♂ ca. 3.20 mm, ♀ ca. 3.60 mm.The male palpal tibia is enlarged and bears projections or tibial apophyses. The dorsal apo-physis of the tibia takes the shape of a broad arrow and there is a slit on it near the margin.Oedothorax rimatus is similar to O. paludigena (Millidge, 1975), but differ from the latter in the shape of tibia and paracybium.2. Oedothorax foratus sp. nov. (fig. 8-15)Holotype ♂, allotype ♀, paratypes 13♂♂ 10♀♀, collected from Shennongjia Forest Region (31°15’-31°57’N, 109°56’-110°58’E), Hubei Province, June-August, 1986.Body length ♂ 3.00-3.80 mm, ♀ 3.20-4.10 mm.The male of O. foratus is similar to O. rimatus, but differs from the latter as follows: 1. O. foratus Tml: 0.61(♂)-0.63(♀), 0. rimatus Tml: 0.71 (♂)-0.73(♀); 2. the dorsal tibial apo-physis of this new species is less narrow than O. rimatus; 3. there is an opening on the lateral wall of palpal tibia of O. foratus, and a rectangular chitinous flake attaches on the inner wall by the opening; and 4. the paracymbium of them are different.
