Helluomorphoides praeustus bicolor
Helluomorphoides praeustus bicolor is a subspecies of ground beetle in the family Carabidae, tribe Helluonini. It is one of two recognized subspecies of H. praeustus, distinguished by its bicolored elytral pattern. The subspecies was described by T.W. Harris in 1828 and occurs in North America, with confirmed records from the United States. Like other members of the genus, it belongs to a group of carabid beetles sometimes referred to as 'bombardier beetles' or 'flanged bombardier beetles' due to defensive chemical capabilities found in related taxa, though specific defensive chemistry for this subspecies has not been documented.
