A Review of the North American Species Ofrhizophagusherbst and a Revision of the Nearctic Members of the Subgenusanomophagusreitter (Coleoptera: Rhizophagidae)

The Nearctic species of the subgenusAnomophagusReitter of the genusRhizophagusHerbst are revised. Four taxa are recognized:R.brunneus brunneusHorn 1879,R.brunneus fenyesiMéquignon 1913a,R.pseudobrunneussp.nov., andR.galbussp.nov. For the other Nearctic species of the genus, a diagnosis, a type material section, and distributional notes are provided. Two new taxa are described,R.minutus rotundicollisandR.pusillus. Seven specific names are treated as new junior synonyms, namely (with the valid name in parentheses):R.longicepsCasey 1916 andR.rectusCasey 1916 (=R.cylindricusLeConte 1866);R.minutus quadriguttatusMéquignon 1913b(=R.minutus minutus Mmnerheim1853);R.remotus luteusMéquignon 1913b(=R.remotusLeConte 1866);R.sculpturatus horniMéquignon 1913b(=R.sculpturatusMannerheim 1852);R.dimidiatus testaceusMéquignon 1913bandR.dimidiatus assimilisMéquignon 1913b(=R.dimidiatusMannerheim 1843). The subgenera nameSyringobidiaCasey 1916 (type species:R.cylindricusLeConte 1866) is treated as a new junior subjective synonym ofRhizophaguss.str. A key to all Nearctic speciesof Rhizophagusis provided with distribution maps of the species.
