New cave-dwelling spiders of the family Dictynidae (Arachnida, Araneae) from Guangxi and Guizhou, China
Twenty-four new spider species of the family Dictynidae from caves of Guangxi and Guizhou in southern China were discovered by Prof. Shuqiang LI.
Twenty-four new spider species of the family Dictynidae from caves of Guangxi and Guizhou in southern China were discovered by Prof. Shuqiang LI, professor of Zoology and head for Department of Invertebrate Zoology. Who lead the researche team explored more than 4000 caves in Guizhou and Guangxi over the last 20 years, and collected 50 families of spiders from these caves.
Dictynidae is relatively species-rich encompassing 587 species in 53 genera. They are distributed worldwide, but more common in temperate countries than in the tropics, and are poorly represented in Australia and Latin America. Before the current study, 48 species in 13 genera were recorded from China, including 3 species known from sub-tropical Guizhou. None were known in Guangxi, an autonomous region with considerable karst formations in sub-tropical southwestern China, bordering Vietnam.
