Cylindrostonotus subg. n.

Etymology: The prefix is derived from Latin cylindrus (cylindric); in reference to the characteristic metasoma with one large cylinder of a tergite behind petiole. The end of the name is the last part of the name of the genus of which this subgenus is a part.

Type species: Euxestonotus lissogastrus sp. n.

Diagnosis: Differs from Euxestonotus s. str. in having female metasoma consisting of only two tergites, the petiole and a large fused one (approaching appearance of metasoma of Holocoeliella Huggert, 1981; but the latter has Platygaster -like mesosoma).
