摘要
浙江有大小岩洞计五、六百个,是全国岩洞最多省份之一。我们于1984年5—6月对杭州的千人洞和卧云洞;建德县灵栖古洞、清风洞和乌龟洞进行了采集。除卧云洞外,其它诸洞均属石灰岩溶洞,卧云洞属裂隙崩塌侵蚀岩洞。这次采集得到多种蜘蛛标本,其中采到弱蛛二种,经研究查对为新种,现报道如下:
Two new species of the genus Leptoneta are described from Lingqi, Qingfen and Wugui Caves lying at the foot of Tiemao mountain in Jiande County, from Qianren Cave lying at the foot of Nangoufeng mountain and Woyun Caves lying at the north foot of Baoshi mountain in Hangzhou City, The Woyun Cave is a crevasse-cave, other caves are limestone-caves.Type specimens are deposited in the Department of Biology, Hangzhou Normal College.Leptoneta hangzhouensis sp. nov. (figs. 1-6)Holotype ♂ , allotype ♀ , paratype 9♂♂ 2♀♀ , Qianren and Woyun Caves, Hangzhou, Zhejiang, May 24, 1984.Length of male is 3.05 mm., carapace brown, six eyes, AME the largest, other eyes almost equal in size, major axes of anterior lateral eyes convergent behind. Length of female is 2.22 mm.This new species resembles L, trispiona, but it may be readily distingushed by the tibia of the palpal organ and the teeth of the chelicerae of male.Leptoneta lingqiensis sp. nov. (figs. 7-15)Holotype ♂ , allotype ♀, paratype 9♂♂ , 12♀♀ Lingqi, Qingfeng and Wugui Caves, Jiande County, May 14, June 11, 1984.Length of male is 1.86 mm., length of female is 2.49 mm.This new species resembles L. huanglongensis and L. trispiona, but can be easily distinguished. L. lingqiensis sp. nov. is remarkable in having a cylindrical process surmounted with two arcuate spinale at dorso-proximal part of palpal organ libia in male. Chelicera brown, with 8 teeth on promargin of fang furrow, 6 extremely small denticle barely visible on retramargin for male.
