7. Bolitophila (Cliopisa) hybrida (Meigen, 1804)

MATERIAL. 1♂, MT2 , 4-10.VI.2015. Total : 1♂.

8. Bolitophila (Cliopisa) sp.

MATERIAL. 1♂, MT2 , 3-17.XII.2015 . Total: 1♂.

REMARKS. The studied specimen is not conspecific to any European species of the subgenus Cliopisa Enderlein. The terminalia are most similar to those of B. (C.) modesta Lackschewitz, 1937 , but can be distinguished by the aedeagal structure and the gonostylus, especially in posterior view. The specimen might be identical to B. (C.) latipes Tollet, 1943 described from Grasdelle (Forêt de Soignes, Belgium), a site in the same forest complex as the Botanical garden Jean Massart and so far known by females only. The study of this putative conspecificity is ongoing and the results will be published elsewhere.
