Zootaxa. 2014 Aug 29;3857(3):301-32. doi: 10.11646/zootaxa.3857.3.1.


The Afrotropical representatives of the spider genus Cheiracanthium C.L. Koch, 1839 from Madagascar and the Comoros Islands are revised, and new species are described. Five described species are recognized: C. africanum Lessert, 1921, C. furculatum Karsch, 1879, C. insulare (Vinson, 1863), C. leucophaeum Simon, 1896, and C. ludovici Lessert, 1921. The internal genitalia of the female of C. insulare, and the female of C. ludovici, are described for the first time. Thirteen new species, C. ambrense sp. nov. (♂♀), C. ampijoroa sp. nov. (♀), C. andranomay sp. nov. (♀), C. anjozorobe sp. nov. (♂♀), C. ashleyi sp. nov. (♂♀), C. fisheri sp. nov. (♂♀), C. foulpointense sp. nov. (♂♀), C. griswoldi sp. nov. (♂♀), C. jocquei sp. nov.

In most of the endemic Madagascan species the female genital depression is divided by a central septum and the male cymbial apophysis is bent distally.
