Fulvius flavicornis Poppius, 1909: 30, 34, 44; Bergroth 1920: 76; Carvalho 1957: 17, 1980: 644; Schuh 1995: 27; Sadowska-Woda 2005: 102; Gorczyca 2006: 35.

Diagnosis.

Eyes contiguous with pronotal collar (Figs 4, 5); antennal segment II yellow, except basal one sixth brownish (Figs 4, 5); basal and apical portions of corium and apex of clavus yellow (Figs 4, 5); left paramere with apical process and paramere body forming obtuse angle, paramere body strongly narrowed medially, broadened apically, apical process elongated, broadened basally, weakly tapering toward apex (Figure 20).

Remarks.

Fulvius flavicornis is most similar to F. subnitens and F. tumidipennis in sharing a yellow patch on the base and apex of the corium and apex of clavus, and the left paramere apical process elongate. Fulvius flavicornis can be distinguished by the coloration of antennal segment II and by the male genitalia.
