Description

Cyclocosmia ricketti, commonly known as the Chinese hourglass spider, is a species of trapdoor spider of the genus Cyclocosmia, which refers specifically to mygalomorphus animals. Cyclocosmia ricketti is native to China and it was first described in 1901 by Mary Agard Pocock.

The abdomen of spiders in this genus is abruptly truncated and ends in a hardened disc which is strengthened by a system of ribs and grooves.

They use this to clog the entrance of their 7 to 15 cm deep vertical burrows when threatened, a phenomenon called phragmosis.

Strong spines are located around the edge of the disk. The four spinnerets are found just anterior to it, with the posterior, retractable spinnerets particularly large.
