Abstract

Representatives of some poorly known spider species collected in the rainforest litter of the Orchid Island (Taiwan) are illustrated and discussed here. A new species, Brignoliella tao sp. nov. (Fam. Tetrablemmidae), endemic to Orchid Island, is described based on both sexes. The previously unknown female of Theridiosoma triumphale Zhao Li, 2012 (Fam. Theridiosomatidae), is described for the first time. Zoma taiwanica (Zhang, Zhu Tso 2006) comb. nov., from the same family, is illustrated and its transfer from the genus Theridiosoma O. Pickard-Cambridge, 1879 to Zoma Saaristo, 1996 is proposed on the basis of morphological characters. Habitus and genitalia of the endemic species Gongylidioides angustus Tu Li, 2006 (Fam. Linyphiidae) are also illustrated.

摘要

本文展示并讨论了在台湾兰屿雨林落叶层中采集到的一些鲜为人知的蜘蛛物种的代表。一种新的物种，Brignoliella tao sp. nov.（Fam. Tetrablemmidae），是兰屿特有的，基于雌雄两性进行了描述。此前未知的 Theridiosoma triumphale Zhao Li, 2012（Fam. Theridiosomatidae）的雌性也首次被描述。同样来自 Theridiosomatidae 科的 Zoma taiwanica（Zhang, Zhu Tso 2006）被重新组合，并根据形态特征建议将其从 Theridiosoma O. Pickard-Cambridge, 1879 属转移到 Zoma Saaristo, 1996 属。此外，还展示了特有的 Gongylidioides angustus Tu Li, 2006（Fam. Linyphiidae）的栖息地和生殖器。
