Whitworth, Terry L. & Yusseff-Vanegas, Sohath, 2019, A revision of the genera and species of the Neotropical family Mesembrinellidae (Diptera: Oestroidea), Zootaxa 4659 (1), pp. 1-146 : 64

Mesembrinella aeneiventris species-group

Recognition. The primary shared character state in the M. aeneiventris species-group is disc of T5 with a horizontal row of stout setae ( Fig. 8 ); remainder of T5 usually with short, fine setae and setulae. In most species, the male has surstylus straight or only slightly curved posteriorly (as in Fig. 45 ), whereas in the M. bicolor species-group the surstylus typically has a distinctive curve posteriorly ( M. cordillera , M. vogelsangi and M. zurquiensis in the M. aeneiventris species-group have surstylus with a more distinct curve directed posteriorly). The area of the phallus anterior to the hypophallic lobes tends to be narrowed ( Fig. 146 ), similar to Laneella .
