A revision of the New Zealand weevil genus Irenimus Pascoe, 1876 (Coleoptera: Curculionidae: Entiminae) Author Brown, Samuel D.

Chalepistes tenebricus (Broun, 1893) new combination Catoptes tenebricus Broun, 1893b:1194 Catoptes aemulator Broun, 1893b:1193 new synonym Irenimus aemulator (Broun) ; Barratt & Kuschel, 1996 :372 , Barratt et al. , 1998 :56 Catoptes argentalis Broun, 1914 :208 new synonym Although C. aemulator has been used as a valid name previously, C. tenebricus is chosen as the senior name, as the holotype of C. aemulator is a teneral specimen and critical characters are not fully developed. The vestiture of C. argentalis is quite different in colour, shape and appearance from that of C. tenebricus ; however no clear structural characters exist to reliably separate the two.
