    0 Introduction

    The family Theridiosomatidae is a small spider group, mainly distributing in leaf litter, caves [1]and under rocks. Up to the present, only 13 species in 8 genera are reported in China. Before

    15 90s in last century, it is blank to study on theridiosomatids in China. Until to 1992, the first

    [2]species, Wendilgarda sinensis, was reported from Hainan Province. Subsequently, the Chinese

    well-known araneologist investigated cave fauna in Yunnan and Hunan, and recorded the other

    [3]one theridiosomatid spider. 2006, the third species in China, Theridiosoma taiwanica, is also

    [4]found and described from Taiwan. The most fruitful study is to research the orb-web

    20 symphytognathoid spiders in the Gaoligongshan region of Yunnan by the scholars cooperation

    between American and Chinese, and the plenty of new spider taxa is described and reported of

    [5]which include 1 new genus, 4 new record genera and 8 new species. The genus Karstia was

    [6~7]erected to accommodate two theridiosomatid species from caves in Guizhou and Guangxi.

    In October, 2010, with the purpose of investigating species diversity of cave spiders, we

    25 carried out expeditions to the region of Chongqing and eastern Sichuan. A considerable number of spider specimens were taken. By the careful examination and identifying, some specimens belong to the theridiosomatid spiders, and were recognized as a new species of genus Karstia. This current paper about the family Theridiosomatidae is reported for the first time from the region.
