Heterodiomus Brèthes, 1925 

Heterodiomus Brèthes 1925:155  . Type species: Heterodiomus darwini Brèthes, 1925  , by subsequent designation of Korschefsky 1931.

Diagnosis. This genus was described but not diagnosed by Brèthes (1925). The species currently included ( Gordon 1999; Gordon & González 2003) are distinguished from other members of the New World Diomini  by the combination of: antennae composed of 11 antennomeres, prosternum shaped like a short stemmed T, long anterior to coxal cavities (subequal to length of cavity), intercoxal process with carinae short, not extending to anterior margin, and suture between abdominal ventrites 1 and 2 partially obliterated. Members of Heterodiomus  are strongly united by the shape of the female genitalia which have a bulbous base to the spermatheca and distally tapered sclerotized sheath in the basal half of the sperm duct (= “thorn-like infundibulum” sens. Gordon 1999). Although this combination of genital characteristics does not occur in the other Diomini  illustrated in Gordon (1999), the corresponding structures in most species have not yet been evaluated, and a very similar configuration ( Fig. 6View FIGURES 3–12) is found in the new genus described herein.
