摘　　要：本文记述了采自湖北省神农架林区的盖蛛属Neriene二新种:鹰喙盖蛛 Neriene aquilirostralis,丽带盖蛛 Neriene calozonata。从外生殖器形态结构对新种与其近似种进行了比较。鹰喙盖蛛与人井盖蛛 N.oidedlcata Helsdingen近似;丽带盖蛛与饰斑盖蛛 N.compta Zhu et Sha 近似,但是,它们在外生殖器形态结构上存在显著差异,可以明确将其区分开。In this paper two new species of spider of genus Neriene are described. All types of the new species are deposited in the Department of Biology, Norman Bethune University of Medical Sciences.1. Neriene aquilirostralis sp. nov. (figs. 1-11)Body length: ♂ 3.94-5.19 mm, ♀ 3.88-5.25 mm.The new species resembles N. oidedicata Helsdingen, 1969 in the colour of body, dorsal pattern of abdomen, male palp and ventral view of epigyne, but differs from the latter in having: (1) the beek-like tip and developed membranous elements of terminal apophysis; (2) 2-3 pairs of light translucent areas of epigyne; (3) different structure of vulva. The new species also resembles some African species (Helsdingen, 1969: 156-191, figs. 206-262), but can easily be distinguished from latters by the shapes of terminal apophysis, embolus, latersl projection of lamella, tip of paracymbium, ventral view of epigyne and dorsal view of vulva.Holotype ♂, allotype ♀, paratypes 7♂♂ and 38♀♀, collected from Shennongjia Forest Region (31°15 -31°57'N, 109°56'-110°58'E), Hubei Province, middle Jun.-middle Aug. 1986.2. Neriene calozonata sp. nov. (figs. 12-18) Body length: o 3.53-4.20mm.The new species resembles N. compta Zhu et Sha, 1986 (Acta Zootaxonomica Sinica 11(2): 163-165, fig. 1) in the ventral and lateral view of epigyne, but differs from the latter in dorsal pattern of abdomen and the structure of vulva.Holotype ♀, paratypes 2♀♀, collected from the same region as N. aquilirostralis, Aug. 7, 1986.The male is not found.
