Dolichopus afroungulatus Grichanov, 2004

MATERIAL EXAMINED. Namibia: Katima Mulilo Distr., Mavunje campsite at:

17°55.141’S, 23°19.073’E, 945 m, 22–26.XI 2012, 1♂, 3♀, A.H. Kirk-Spriggs, Malaise trap,

Kwando River floodplain [ BMSA].

DISTRIBUTION. Type locality: South Africa : Natal, Nseleni Nature Res. DR Congo,

Ethiopia, Namibia, South Africa, Zambia.

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.
