REDEFINITION OF THE OPATRINE TRIBES IN NORTH AMERICA WITH NOTES ON SOME APTEROUS GENERA (COLEOPTERA: TENEBRIONIDAE: TENEBRIONINAE)

Abstract

The opatrine lineage of the subfamily Tenebrioninae is redefined for the Nearctic region of North America. The genera Hyocis, Gonocephalum and Cyclosattus are not North American. The relationships of the genera Alaudes, Tonibiastes, Nocibiotes and Tonibius are discussed. Tonibius rossi Blaisdell is transferred to Nocibiotes. The species is illustrated and a modified generic diagnosis is provided for Nocibiotes. A revised key is presented for the Nearctic members of the opatrine tribes and genera.
