Remarks.
This species was described from more than one specimen since the original description refers to other specimens in the Reiche, Aubé and Chevrolat collections. The study of the
type
confirmed the current interpretation of the species.
Lixus bidens
can be recognized by the rostrum cylindrical, subequal in length to prothorax, nearly straight and narrowed from base to antennal insertion; middle and hind tibia widened at apex, apical fringe continued on lateral sides; elytra apex sharp, apices not divergent.
Lixus bidens
is related to
Lixus umbellatarum
(Fabricus, 1787)
and
Lixus siculus
Boheman
but differs from the latter in lacking a convex line on elytral interval 3 at base and lacking divergent protuberances of the elytral apex; apex of middle and hind tibia of
L. umbellaturum
strongly widened, apical fringe longer on lateral sides, rostrum longer and curved, tarsi distinctly wider.
