Epirhyssa brianfisheri Rousse & van Noort, 2014 Figs 3-6

Material examined.

Type material: CENTRAL AFRICAN REPUBLIC:

• 1 ♀, holotype; Préfecture Sangha-Mbaéré, Réserve Spéciale de Forêt Dense de Dzanga-Sangha (12.7 km, 326 degrees NW of Bayanga); 3°00.27'N, 16°11.55'E; alt. 420 m; 13 May 2001; Simon van Noort leg.; Sweep; CAR01-S158; Lowland rainforest; SAMC SAM–HYM–P 048018.

Known material: One specimen (1 ♀, see Rousse and van Noort 2014, data above).

Diagnosis.

This species can be distinguished from other Afrotropical Rhyssinae by the combination of an elevated hypostomal flange, the absence of a raised flange on the dorsal margin of the mesopleuron, an elliptical apical horn of the metasoma, and a finely punctate (over 50% of surface) tergite 3. In practice its colour pattern makes it instantly recognisable.

Head: frons with median carinae converging before continuing towards median ocellus, without lateral carinae; hypostomal carina raised into an elevated flange, its height 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 punctate.

Distribution.

Central African Republic.
