两种筛器类蜘蛛的微细构造研究

Study on Fine Structure of the Two Spider (Metathelae: Cribellatae)

本文对新蛛亚目、筛器类的类褛网蛛（ＰｓｅｃｈｒｕｓｍｉｍｕｓＣｈａｍｂｅｒｌｉｎ）和居室拟壁钱（Ｏｅｃｏｂｉｕｓｃｅｌａｒｉｏｒｕｍ（Ｄｕｇｅｓ））两种蜘蛛，在扫描电镜下反复观察，拍摄了大量照片．对筛器及其筛器纺管，前、中、后纺器及其大纺管和小纺管，感觉器———听毛、触毛等进行了描述与测量．首次发现类褛网蛛初孵化的幼蛛有纺器而无筛器．

This paper deals with the spiders Oecobius cellariorum (Duges) and Psechrus mimus chamberlin. The external fine structures of the two spiders (Metathalae: cribellatae) have been observed and measured by scanning electroscopy, in which cribellum, anterior spinneret, median spinneret, posterior spinneret and sensillum were studied in detail.
