Genus Chrysotus MEIGEN

Chrysotus comprises over 320 named species worldwide. We here follow ROBINSON and VOCKEROTH (1981) ’s delimitation of the genus, assigning to Chrysotus only species with the following combination of characters: upper part of proepisternum bare; setae of calypter dark or pale; face narrowed below or parallel-sided; male fore tarsus with or without claws; male tergite 6 at least with one seta (usually many); setae on male sternite 8 not longer nor stronger than those on tergite 6.

All species treated below and originally described as Diaphorus have that set of characters and are hence transferred to Chrysotus . Nevertheless, the above mentioned characters also fit Achradocera BECKER , Falbouria DYTE , and Lyroneurus LOEW (see CAPELLARI & AMORIM 2012 for further discussion). The issue of transferring these species in this paper from Diaphorus to Chrysotus is in fact a matter of keeping at least a clear composition of Diaphorus . The paraphyly of Chrysotus is much more complicated and demands a broader study of the genus.
