摘　　要：本文记述采自四川和安徽的管巢蛛科红螯蛛属蜘蛛一新种——拟邻红螯蛛Chiracanthium adjacensoides sp.nov.。本新种与邻红螯蛛Ch.adjacens Cambridge虽近似,但有明显区别。Chiracanthium adjacensoides sp. nov. (figs. 1-4)Holotype ♀, allotype ♂, Chongqing, Sichuan (29°5’E, 106°5’E), October 16, 1983; paratype 1 ♂, Miyi, Sichuan (26°8’N, 102°1’E), August 9, 1980; 1 ♀, Chengdu, Sichuan (30°6’N, 104°1’E), September, 1980; 1 ♀, Junlian, Sichuan (28°1’N, 104°5’E), July, 1980; 1♀ 1 ♂, Yongchuan, Sichuan (29°3’N, 105°1’E), August, 1981; 2 ♀♀, Xuancheng, Anhui (30°9’N, 118°7’E), June, 1976. All the type specimens are kept in the Institute of Zoology, Academia Sinica.Female Total length 6.55-12.36 mm. A specimen of 8.78 mm measured: carapace 3.71mm long, 2.60mm wide; abdomen 4.70mm long, 3.34mm wide. Carapace yellowish or reddish brown, highest just anterior to dorsal groove. Anterior eye row slightly recurved, posterior row nearly straight. Dorsal groove shallow, inconspicuous. Chelicerae dark brown, with two teeth and one denticle on each margin of fang furrow. Abdomen elongate-oval, yellow. Epigynura with concave plat. Copulatory tubes extending anteriad, then posteriad; spermathe-cae small, nearly round, situated near genital groove.Male Total length 5.69-11.12mm. A specimen of 6.80mm measured: carapace 2.97mm long, 2.22 mm wide; abdomen 3.71 mm long, 1.98 mm wide. Tibial retrolateral apophysis slight curved at middle part, end pointed; spur of cymbium tapering to a sharp point and directed outwards, crossing the retrolateral apophysis of tibia. Basal half of cymbium roundish, the fore half somewhat cylindrically attenuate, the division between the two portions being well marked, but lacking a sudden notch-like depression on the outer side.The new species resembles Chiracanthium adjacens Cambridge, (1885: 24-26, pl. 2, fig. 17), but differs from the latter in lacking a sudden notch-like depression on the outer margin of male cymbium as well as in the different size and shape of concave plate of female epigynum.
