NOTES. The species is the only native Afrotropical species of the mainly Holarctic genus
Dolichopus
(Grichanov, 2018)
. It keys (Negrobov
et al
., 2005) to the Palaearctic
D. ungulatus
Linnaeus, 1758, differing from the latter species in the presence of stublike wing vein M
2
,
flattened laterally 2nd–4th segments of mid tarsus, long distal process on cercus and many other characters (Grichanov, 2004). Hind basitarsus of
D. afroungulatus
bears one short middorsal seta, 1.5 times longer than diameter of tarsomere, similar to that in some
Lichtwardtia
species.
Nevertheless, the presence of only one stump vein (M
2
), the short-haired stylus, the overall habitus and especially the hypopygium morphology (Grichanov, 2004)
distinguish clearly
D. afroungulatus
from
Lichtwardtia
.
Epandrial lobes of the
Lichtwardtia
hypopygium are greatly reduced, usually to simple or pedunculate ventral setae. In contrast,
both distoventral and basoventral epandrial lobes are generally large and strongly projected in
Dolichopus
species.
