Comments. Figures 6 - 1 and 6 - 2 in the original description illustrate the anterior head and the female antenna, both of which indicate that this species belongs in Gryon . The holotype specimen is mounted in a way that prevents observation of the lateral mesosoma (Cristina Vasilita , personal communication), but the presence of a complete mesopleural carina is visible on some of the paratype specimens, which have identical collection data. Also, in the paratype specimen photographed, the acetabular carina and ventral mesopleural carina do not intersect ventrally, providing another character by which this species may be separated from G. aetherium . The medial infuscation of the fore wing, illustrated in Figure 5 - 1 of the original description, is similar to that of G. fasciatum , which was described from Egypt. Because G. oligomerum was described from Israel, these species should be compared in future work.
