Diagnosis
.
Of the African species of
Sibianor
, the new species is most similar to
S. victoriae
(cf.
Logunov 2001
: figs 292, 293), described from a single male from
Kenya
.
S. anansii
sp. n.
differs in having a wider tibial apophysis, which is also of a different shape (
Fig. 39
). The female of
S. anansii
sp. n.
differs from all the known
Sibianor
Figures 33-37.

species in having longer insemination ducts (
Fig. 41
). Besides, the entire body of both sexes of
S. anansii
sp. n.
is covered with white scales (
Figs 33-17
), which is not the case of
S. victoriae
(see
Logunov 2001
: p. 276).
Etymology
.
The new species is dedicated to the spider Anansi, a popular figure in the folklore of West Africa (the
Ashanti
of
Ghana
), appearing as a cunning trickster and the King of all Stories.
