First description of the male of Morellia (Trichomorellia) callidimera (Bigot) (Diptera, Muscidae), with examination of type material

Morellia (Trichomorellia) Stein, 1918 is a Neotropical subgenus with eight known species occurring from Mexico to Argentina. Morellia (T.) callidimera (Bigot) was described in 1887 based on a female specimen from Mexico. The male of M. (T.) callidimera is described here for the first time, 139 years after the original description, including images of the habitus and drawings of the male and female terminalia. The female holotype of M. (T.) callidimera and its junior synonym M. (T.) fulvipes were examined and redescribed. Morellia (T.) callidimera is recorded from Veracruz (Mexico) for the first time.
