Type species: Anchomenus pubescens Dejean, 1828 by monotypy. Etymology (original). From the Greek a (privative) and tranos (clear, distinct), possibly alluding to the obscure relationships of the genus to the eyes of LeConte [masculine]. Diversity. Two species in the temperate regions of eastern North America ( Atranus pubescens ) and Europe ( Atranus ruficollis Gautier des Cottes). Identification. Lindroth (1968: 649) commented on the structural differences between the two species.
