Diagnosis.
Diagnosis and description of the genus is given in
Lotz (2007a)
. In most
Cheiracanthium
species the PMT:RMT ratio is 3:3, but in most of the new Madagascan species there are more than three RMT and sometimes only two. This is illustrated in the figures for each species to be consistent with previous publications.
Relationships.
In relation to the continental African species, most of the endemic Madagascan species differ in the female genital depression being divided by a central septum and the male cymbial apophysis being bent distally. The bent cymbial apophysis is also found in
C. canariense
Wunderlich, 1987
, from Canary Islands,
Turkey
and
Egypt
, and
C. knipperi
Lotz, 2011
, from
Tanzania
, but without the divided genital depression in the females. In most continental African species the female genitalia has a single oval depression and the male cymbial apophysis is directed proximally.
Distribution.
In the Afrotropical Region species of
Cheiracanthium
have been collected from most countries and islands.
