Comments: The finding of the male of
M. russata
(
Figs 27
,
57–
63
), so long after the ♀
holotype
, allows us to comment on the species’ taxonomic assignment. The palp conformation of
M. russata
, particularly the shape and position of the embolus and the sclerotized lobe M
2
(
sensu
Wanless
1984
a
, fig.
27
G
), is almost identical to that of
Veissella milloti
(Logunov & Azarkina
2008
, figs
107–111
). Both species differ from each other in details of mutual arrangement and size of the embolus and the sclerite M
2
, as well as in the shape of tibial apophysis (cf.
Figs
57–59
). Yet,
V. milloti
was only provisionally placed in the genus
Veissella
(Logunov & Azarkina
2008
:
113
)
, as the species has no process on the palpal femur and patella, the key diagnostic character of
Veissella
(see Wanless
1984
a
).
There is no doubt that both
M. russata
, known from Madagascar, and
V. milloti
, known from the Comoros, belong to the same genus, but whether it should be
Meleon
,
Veissella
or a separate genus remains to be further studied. On the one hand, the female of
M. russata
does not possess the median epigynal guide, another key character of
Veissella
(see Wanless
1984
a
, fig.
27
E
). Yet, as was stressed by Wijesinghe (
1994
:
59
),
M. russata
differs from the true
Meleon
species in the profile of its carapace and the very short copulatory ducts. Thus, it is very likely that
M. russata
and
V. milloti
should be placed in a genus of its own, separated both from true
Meleon
(
sensu
Wijesinghe
1994
)
and from
Veissella
.
