Thread subject: :: Empis - not scutellata but dimidiata

Posted by Sundew on 17-06-2021 13:24

According to the partly yellow antennae and the short first antennal segment I consider this male Empis scutellata. As far as I know there is no other member of subgenus Xanthempis that has such antennae. Seen in southwestern Germany (50 km west of Stuttgart) on 12th June.
Thanks for comments, Sundew

Do you agree?

This is Empis (Leptempis) dimidiata Meigen.

Dear Igor, what a surprise! So this yellow one belongs to Leptempis. The species is said to be rare and endangered in Germany. I do not know any literature about it; is there a European Leptempis key where it is included? In Chvala (1994) it is not mentioned.

There is no modern key for this complex of species. It includes three very similar European species (all with yellow mesoscutum and a median vitta): E. dimidiata Mg., E. mesogramma Loew and E. divisa Loew. You could find them in Lindner's "Die Fliegen, S. 401" (Rhagionempis =Leptempis), where E. monogramma Meig. = E. mesogramma Lw. and E. scutellariae Bezzi = E. dimidiata Mg.
Best wishes,
