Clark, Shawn M. & Anderson, E. Russell, 2019, A Review of Triarius Jacoby, 1887 (Coleoptera: Chrysomelidae: Galerucinae: Luperini), with Descriptions of a New Genus and Four New Species, The Coleopterists Bulletin 73 (2), pp. 343-357 : 356

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 .
