Comments.

After examining the holotype, we conclude that this species belongs to genus Aulacidea . After determining the specimen following the Palaearctic Aulacidea species key made by Melika (2006) we conclude that this species is a valid species related to Aulacidea laureae Nieves-Aldrey, 1992 and Aulacidea follioti Barbotin, 1972. The three species present the head broader than high, 13-segmented antenna, F1 shorter than F2, incomplete notauli and ciliated forewing margin. Aulacidea idoneus differs from Aulacidea follioti in presenting median mesoscutal line, like Aulacidea laureae ; Aulacidea idoneus can be distinguished from Aulacidea laureae by the following characters: short and narrow scutelar foveae, OOL 3.0 times longer than the diameter of lateral ocellus, space between totuli and clypeus without radiating carina, having shorter notauli and medial mesoscutal line shorter (both extending 1/3 of scutum length) and radial cell (slightly more than 2.0 times longer than broad) and having a second metasomal tergite with only some dorsal points while being laterally smooth.
