Megarhyssa babaulti Seyrig, 1937 Figs 72-75

Material examined.

Type material: DEMOCRATIC REPUBLIC OF CONGO:

• 1 ♀, holotype; "reg. Lac Kivu", “Kadjudju” [Kajuju, 02°09'S, 28°54'E]; 1932; MNHN EY8831.

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 presence of a closed areolet. No other species has the same colour pattern.

Head: frons with median carinae diverging towards ocelli, 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 laterally absent.

Metasoma: tip of apical horn almost circular in posterior view; tergite 3 mostly smooth.

Distribution.

Democratic Republic of Congo.
