Megaselia nigricia Disney & Durska, 2011: 4 (male)

Diagnosis. This species was described from a single male from Poland. It closely resembles M. nigrescens (Wood) . Indeed, the hypopygia are very alike. Unfortunately, the front legs of the holotype were damaged and only the incomplete front tarsus of one leg remained. The specimens from Denmark allow a clearer distinction. Thus, the fore tarsus of M. nigrescens has posterodorsal hair palisades on segments 1 to 4 only ( Fig. 172 ); whereas in M. nigricia they are present on all five segments ( Fig. 171 ). In addition, the postpedicels of M. nigrescens lack SPS vesicles ( Fig. 170 ) but are present in M. nigricia ( Fig. 169 ).
