Abstract

Background: The spider family Ctenidae Keyserling, 1877 has a worldwide distribution with 580 species belonging to 49 genera, of which 109 species of six genera are distributed in Southeast Asia.

New information: Four new species of ctenid spiders are described from Southeast Asia: Anahitamenglun sp. n. (Yunnan, China), Bowiehaiphong sp. n. (Hai Phong, Vietnam), Bowiemengla sp. n. (Yunnan, China) and Bowiezhengi sp. n. (Yunnan, China). In addition, the female of Sinoctenuszhui Marusik, Zhang & Omelko, 2012 (Hainan, China) is described for the first time.

Keywords: biodiversity; morphology; new species; taxonomy.
