Variability.
Aedeagus of the studied specimens is identical with
types
(see
Fig.
8
in
JANÁK 2007
). Median impressions on the disc of the head is very shallow and rounded, not longitudinal as in
O. rostrifer
Puthz, 1968
or
O. ndumu
sp. nov.
For this reason,
O. ruthae
should be placed in the key in the proximity of
O. microps
(
Kistner, 1967
)
and not of
O. rostrifer
Puthz, 1986
, as previously done by
JANÁK (2007)
.
Distribution.
Octavius ruthae
has been recorded only from Mbotyi and Ntsubane Forest.
