Etymology
. The specific name refers to the
type
locality, noun in apposition.
Diagnosis.
Males of
K. ruwenzori
sp. nov.
are distinguished from those of the other species of the genus by the palp with a distally bifid RTA (simple in
K. rutshuru
sp. nov.
and
K. buta
sp. nov
.
) (
Figs 49E
,
50C
); females differ by the positioning ridges oblique and separated from each other, with an excavated area between the copulatory openings (positioning ridges touching in
K. rutshuru
sp. nov.
and
K. buta
sp. nov
.
) (
Fig. 50D
).
