Diagnosis.

This species can be distinguished from other Afrotropical Rhyssinae by the combination of a half-elliptical apical horn of the metasoma and a punctate (over 50% of surface) tergite 3. Epirhyssa uelensis is also predominantly yellow with black spots, but its subalar prominence has a lateral flange.

Head: frons with weak median carinae converging before continuing towards median ocellus, without lateral carinae; hypostomal carina raised into a low flange, its height slightly less than or equivalent to the maximum width of the second maxillary palp segment.

Mesosoma: subalar prominence without a lateral flange; mesopleuron without a flange along the dorsal margin; epicnemial carina reaches the approximate height of the mesopleural pit.

Metasoma: tip of apical horn half-elliptical in posterior view; tergite 3 densely punctate.

Additional or updated characters.

Apart from the diagnosis, we provide the following additional or updated character traits to the description in Rousse and van Noort (2014).

Female.

Body length 7.2 mm– 12.7 mm. Frons without rugae or with faint lateral rugae curving towards lateral ocelli. Face punctate or transversely rugulose-punctate. Clypeus longitudinally strigose and sparsely punctate. Antenna with 28-29 flagellar segments. Tergites 1 mostly smooth, 2-7 punctate (2 sometimes only punctate laterally), anterior margins of 5-6 often striate, tergite 1 1.2-1.5 times as long as apically wide. The Ugandan specimens have black anterior median spots on tergites 1-7 (ranging from very small on tergite 1 to reaching posterior margin on tergite 7), not just on tergites 4-7.

Distribution.

Cameroon. New record: Uganda.
