Abstract

Background: The spider family Ctenidae Keyserling, 1877 has a worldwide distribution with 584 species belonging to 49 genera. Amongst these, 141 species are from Asia, including 130 species assigned to Cteninae Keyserling, 1877.

New information: Nine new species belonging to three genera of Cteninae are reported from Asia: Amauropelmakrabi sp. n. (female; Krabi, Thailand), Am.phangnga sp. n. (male; Phang Nga, Thailand), Am.saraburi sp. n. (male and female; Saraburi, Thailand); Anahitamedog sp. n. (male and female; Tibet, China); Bowieninhbinh sp. n. (male; Ninh Binh, Vietnam) and B.vinhphuc sp. n. (male and female; Vinh Phuc, Vietnam) from the robustus-species group; B.borneo sp. n. (male; Sabah, Malaysia) from the chinagirl-species group; B.engkilili sp. n. (female; Engkilili, Malaysia); B.sabah sp. n. (male and female; Sabah, Malaysia) from the scarymonsters-species group. The male of An.popa Jäger & Minn, 2015 and the female of B.fascination Jäger, 2022 (robustus-species group) are described for the first time. B.fascination Jäger, 2022 is reported from China for the first time. In addition, the DNA barcodes of all the species in this study were obtained, except for B.vinhphuc sp. n.

Keywords: DNA barcode; biodiversity; morphology; new species; tropics and subtropics.
