Comments: Until now, this species has been reported as being known from the female only and from a few localities in South Africa (Wanless
1984
b
; Wesołowska & Haddad
2009
). Caporiacco (
1947
) reported a single male of
C. nigrimana
collected from East Africa (Pangani), but provided no illustration or description of this male. It remains unclear how the latter author could match the single male he studied with
C. nigrimana
described from a single female by Simon (
1900
). The problem of what species was reported by Caporiacco under the name
C. nigrimana
requires further attention.
Figs 14–16.
Cyrba nigrimana
Simon, 1900
from South Africa (♂ – Port Elisabeth; ♀ – Limpopo, Little Leigh), general appearance: (14, 15) male, ventral and dorsal views; (16) female, dorsal view. Scale bars: 1 mm.
The male of
C. nigrimana
(
Figs
17–20
) is most similar (almost identical) to that of
Cyrba boveyi
, described by Lessert (
1933
) from a single male and redescribed on the basis of both sexes by Wanless (
1984
b
, figs
10
A
–
L
). The latter author only provisionally matched the male of
C. boveyi
with the female from Kenya, which was selected because of its ‘most unusual epigyne’ (Wanless
1984
b
:
465
). The males of both species seem to differ in the slightly different shape of the tibial apophysis and of the sclerotied lobe M
2
(
sensu
Wanless
1984
a
). Furthermore, the male of
C. boveyi
has its body covered with bright orange hairs (see Wesołowska & Haddad
2009
, fig.
238
), as in
C. simoni
, whereas the male of
C. nigrimana
is otherwise (
Figs 14, 15
). We have matched the male and females of
C. nigrimana
on the basis of their virtually identical body colouration (
Figs
14–16
). However, this matching must be considered provisional until a sample containing both sexes has been collected.
