Extract

There are five known species of the genus Hylobius in North America. These are H. congener Dalla Torre, Schenkling and Marshall, H. pales (Herbst), H. radicis Buchanan, H. pinicola (Couper) and H. warreni Wood. Buchanan (1934) recognized the first three species and indicated that “there might be one or two additional races or species”. He also stated, “Hypomolyx piceus Deg. is placed in Hylobius in the Junk catalog; it differs from the above 3 in its untoothed femora.” Wood (1957) recognized H. pinicola (Couper), invalidated the generic name Hypomolyx, and erected a new species, Hylobius warreni. He briefly described the new species and presented a taxonomic key by which it could be distinguished from H. pinicola and a Eurasian species, H. piceus (DeGeer). It is now clear that Hypomolyx piceus as referred to by Warren (1956a, 1956b) actually consisted of two species, Hylobius pinicola and H. warreni.
