On Craspedocerus Aurivillius, 1900

According to Aurivillius (1900) regarding Craspedocerus (translated): “antennomeres III–V tumid, dense setose ventrally;” and “Closely related to Ptericoptus and Bisaltes , but immediately distinguished from both by the elongated lower eye lobes.” Of these features, only the densely setose ventral surface of antennomeres III–V may, eventually, be used to separate this subgenus, because the other species currently included in it do not have the basal antennomeres distinctly tumid as in the type species ( C. poecilus Aurivillius, 1900 ( Fig. 34 )).

Breuning (1942) considered Craspedocerus as a subgenus of Bisaltes and reported (translated): “Very close to poecilus Auriv. , but the lower eye lobes noticeably longer than the genae, prosternal process somewhat recurved backward, the metatibiae not so excessively extended; the elytra without a postmedian dark band.” Later, Breuning (1971a) separated Bisaltes (Bisaltes) from Bisaltes (Craspedocerus) in his key as follows (translated): “Antennomeres III-V not tumid,” leading to Bisaltes (Bisaltes) ; “These articles tumid,” leading to Bisaltes (Craspedocerus) . Even so, Breuning (1971a), incomprehensibly, included B. pictus Breuning, 1940 ( Fig. 33 ) in Bisaltes (Bisaltes) and B. ptericoptoides Breuning, 1942 ( Fig. 32 ) in Bisaltes (Craspedocerus) , although both have a similar general appearance and identical antennal shape. Galileo & Martins (2003) transferred B. pictus to B. ( Craspedocerus ). Furthermore, still more incomprehensibly, Breuning (1971b) included B. columbianus Breuning, 1971 in Bisaltes (B.), although the antennae are identical to that of B. poecilus . It is important to note that there are other species currently included in Bisaltes (Bisaltes) with the ventral surface of the basal antennomeres somewhat densely setose, as for example, B. (B.) adustus ( Burmeister, 1865) .
