A Review of Triarius Jacoby, 1887 (Coleoptera: Chrysomelidae: Galerucinae: Luperini), with Descriptions of a New Genus and Four New Species Author Clark, Shawn M. Author Anderson, E. Russell text The Coleopterists Bulletin 2019 2019-06-21 73 2 343 357 http://dx.doi.org/10.1649/0010-065x-73.2.343 journal article 10.1649/0010-065X-73.2.343 1938-4394 Diabrotica neotropica Clark and Anderson , replacement name Triarius tropicus Weise 1921: 85 Diabrotica tropicus : Smith and Lawrence 1967: 135 (not Diabrotica tropica Weise, 1916 ) This Brazilian species was originally named Triarius tropicus Weise, 1921 . Later, Smith and Lawrence (1967) transferred it to the genus Diabrotica . However, in so doing, they created a secondary homonym with Diabrotica tropica Weise, 1916 . The fact that the 1916 species is now placed in Paratriarius Schaeffer does not diminish the homonymy, as the original combination was in Diabrotica . We here propose Diabrotica neotropica as a replacement name for Triarius tropicus Weise, 1921 .
