Other: Westwood 1843: 93 (none - as Euparia nigricans ), 1847: 240 (none - as Euparia nigricans ); A. Schmidt 1910b: 42 , 72 (America - as Euparia nigricans ), 1922b: 397 (America - as Euparia nigricans ); Blackwelder 1944: 213 (not mentioned - as Euparia nigricans ). Note. According to Stebnicka (2009a: 17) , Iarupea nigricans is described as Ataenius nigricans in Westwood (1847: 240) . This is the “memoir” in the Transactions of the Entomological Society of London in which Westwood gives a detailed description of this species, as read by him in the meeting of that society on August 7, 1843 . However, a brief description is already given in Westwood (1843: 93) , which is published in the Proceedings of the same society that summarize that meeting. We suspect that Stebnicka was not aware of this earlier description, resulting in her use of an incorrect year of description.
