Remarks:
The recently redescribed and illustrated
Corinna natalis
is a very large corinnine spider (
Haddad 2005
) that shares a number of characters with
Messapus martini
and other undescribed
Messapus
, as detailed in the generic description above. Particularly, the similarities in leg spination, abdominal sclerotisation and male palpal morphology, together with support from the phylogenetic analyses (
Fig. 26
), confirms that
C. natalis
is congeneric with
M. martini
, and its transfer to
Messapus
is hereby proposed.

Distribution:
Previously known only from the KwaZulu-Natal Province,
South Africa
(
Haddad 2005
). Newly recorded from the Mpumulanga and Limpopo Provinces, and from southern
Mozambique
(
Fig. 40
).
Biology:
The biology of this species was briefly discussed by
Haddad (2005)
. This species constructs a silken retreat in fissures of bark or cerambycid exit holes in the trunks of trees (
Fig. 6
). The structure of the retreat is similar to that of
M. martini
, described above, comprising a silk mat covering the substrate surface, a mat closing the two opposite walls of the fissure, a folded silk opening on the upper side of the retreat, and an attachment line extending to the substrate above the retreat.
