Remarks.

Adults of M. dominicensis were common in fogging samples and Malaise traps, and in 2017 were commonly seen on and collected from trunks of a wide variety tree species. Numerous males taken by fogging and in Malaise traps, presumably teneral, have the hypopygium yellowish rather than brown. Bickel (1985) indicated that M. dominicensis is closely related and could be conspecific with M. nova Van Duzee from eastern North America. Comparison of male specimens of M. nova (Pennsylvania, Virginia) with specimens of M. dominicensis reveals substantial and consistent differences in the form of the cercus and surstylus, notably the presence of branched hairs on the surstylus of M. dominicensis .
