Variation. In one of the examined females the eye height was about 1.3X as long as its length (as in some M. penetrans ). Rarely, F4 can be distinctly smaller than F5.

Comments. This species most closely resembles M. penetrans (Kirby) , M. gibsoni sp. nov. and M. noyesi sp. nov. The main character that separates females of M. conjungens from those of M. penetrans , i.e. the bare area between the stigma and the apex of forewing, which is present in M. penetrans but absent from M. conjungens , is difficult to assess in some cases and needs careful examination with light coming from the correct angle (Figs 21–22).

Distribution. Croatia, Czech Republic, Germany, Kazakhstan, Netherlands, Serbia, Sweden, U.K. ( Noyes 2003), Romania ( Mitroiu 2008).

Hosts. Unknown.
