Taxonomic remarks:
This specimen slightly differs from the
types
described by
Russell-Smith & Jocqué (1986)
by its smaller size (1.28
versus
1.64), as well as by the curved tailpiece and its tapering proximal end.
Distribution:
Known only from Nairobi and Lake Naivasha,
Kenya
(
Russell-Smith & Jocqué, 1986
and present paper).
