Epirhyssa leroyi Benoit, 1951 Figs 21-24

Material examined.

Type material: DEMOCRATIC REPUBLIC OF CONGO:

• 1 ♀, holotype; Bambesa [03°28'N 25°43'E]; Dec. 1933; "J.V. Leroy"; RMCA RMCA-ENT-000017923

• 1 ♀, paratype; Ubangui-Bumba; Dec. 1939; H. de Saeger; RMCA RMCA-ENT-000017924.

Known material: Two specimens (2 ♀, see Rousse and van Noort 2014, data above).

Diagnosis.

This species can be distinguished from other Afrotropical Rhyssinae by the combination of converging median carinae on the frons, the absence of lateral carinae on the frons, an epicnemial carina that reaches high onto the mesopleuron, and a mostly smooth tergite 3. No other species is known to have a black mesosternum.

Head: frons with median carinae converging before continuing towards median ocellus, without lateral carinae; hypostomal carina raised into an elevated flange, its height slightly greater than 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 elliptical in posterior view; tergite 3 mostly smooth.

Distribution.

Democratic Republic of Congo.
