Hartop, Emily A., Brown, Brian V. & Disney, R. Henry L., 2015, Opportunity in our Ignorance: Urban Biodiversity Study Reveals 30 New Species and One New Nearctic Record for Megaselia (Diptera: Phoridae) in Los Angeles (California, USA), Zootaxa 3941 (4), pp. 451-484 : 480

Megaselia wiegmanae new species ( Figs. 30 , 62 , 92 , 124 )

Diagnosis. Male. In the group VIII key of Borgmeier (1966), M. wiegmanae fails the key at couplet 11 where it lacks either the enlarged genitalia of M. globipyga Borgmeier or the large hypandrium of M. brevicostalis Wood. M. wiegmanae , like M. brevicostalis , is part of the M. curtineura complex of Megaselia , and the two species are similar. In addition to the aforementioned large hypandrium of M. brevicostalis , M. wiegmanae has a slightly longer costal index (0.42–0.44 compared to 0.40–0.43), and only 2 alular setae (3 in M. brevicostalis ) ( Fig. 92 ).
