摘要/Abstract

摘要： 拟环纹豹蛛（Pardosa pseudoannulata）为狼蛛科豹蛛属动物，为了探究游猎型蜘蛛接收外界信号的机制，通过对拟环纹豹蛛体表进行扫描电镜观察，分析拟环纹豹蛛体表感受器的类型、分布及特征。结果显示，拟环纹豹蛛的单个裂缝感受器主要分布在触肢的跗节与胫节，数量较少，在整个触肢只能发现1~2个单个裂缝感受器；竖琴器在拟环纹豹蛛体表分布广泛，螯肢、触肢、步足均有发现，且胫节分布较多；而跗节器则见于触肢端部的前跗节上，其形态似水滴状小孔，为圆形或椭圆形空洞。

Abstract: The wolf spiders Pardosa pseudoannulata are members of the genus Panthera belongs to family Lycosidae. In order to explore the mechanism of receiving external signals of vagabundae spiders， the types， distribution and characteristics of surface receptors of Pardosa pseudoannulata were observed by the scanning electron microscope （SEM）. The results showed that there were a few single slit sensilla present on the palpal tarsus and tibia， actually， only one or two single slit sensilla were found on the whole pedipalps. Lyriform organs were widely distributed on tibia， pedipalps， foot step， especially on tibia. The tarsal organs were located on pedipalps， their shapes resembled the water drop shaped holes， round or oval holes.
