Differential diagnosis

Barkalov & Cheng (1998) described Cheilosia lucida based on the male sex, and the taxon was placed in the subgenus Convocheila Barkalov, 2002 . Barkalov & Cheng (2004) described the female. The structure of the distiphallus (apical sclerite of the aedeagus) and the shapes of the strongly asymmetric superior lobes and surstylus are very different from other species of Convocheila (see Barkalov 2002: 230; Barkalov & Cheng 2004: 395; Radenkovic et al. 2020). In addition, Cheilosia lucida has a characteristic lustrous green shine (reflection) of the thorax and strong black bristles on scutellum margin, characteristics not shared by other members of the subgenus Convocheila . Thus, the subgeneric classification of this species requires further study. From all species of Cheilosia , C. lucida differs by the combination of the mentioned characters.
