Distribution. Morocco (new record), Tunisia ( Marshall 1897).

Diagnosis. The male, reported and described herein for the first time, is macropterous. This species actually belongs to the subgenus Chelonorhogas Enderlein , not the subgenus Aleiodes as indicated in Yu et al. (2005), based on the following features: hind tarsal spur long, radial cell of hind wing in male distinctly widened apically, and mesosoma without granulate sculpture.

Remarks. Yu et al. (2005) indicate that a lectotype was disgnated for Rogas hemipterus Marshall, 1897 in Papp (2003). However, Papp (2003) merely mentioned “Female lectotype in The Natural History Museum, London (3.c.243).” This does not satisfy article 74.7.3 of the International Code of Zoological Nomenclature because Papp (2003) did not include an express statement of deliberate designation ( International Commission on Zoological Nomenclature 1999, 2003).
