Replacement name for Cleta Mulsant, 1850 (Coleoptera: Coccinellidae: Epilachnini)

Abstract

Recently the classification of the ladybird beetles’ tribe Epilachnini was revised based on morphological and molecular data (Szawaryn et al. 2015, Tomaszewska & Szawaryn 2016). Based on these findings a new classification of the tribe was proposed. The genus Epilachna Chevrolat in Dejean, 1837 sensu lato was split into several clades, with Epilachna sensu stricto limited to New World fauna, and one of the Afrotropical clades, formerly defined as Epilachna sahlbergi-group (Fürsch 1963), has been named Chazeauiana Tomaszewska & Szawaryn, 2015 (Szawaryn et al. 2015), with Epilachna sahlbergi Mulsant, 1850 as the type species. However, that taxon received an unnecessary replacement name, as Mulsant (1850) already described a subgenus of Epilachna named Cleta distributed in Afrotropics, with Epilachna eckloni Mulsant, 1850 as the type species, which also belongs to the E. sahlbergi-group. Consequently Cleta has been elevated to the genus level (Tomaszewska & Szawaryn 2016) and Chazeuiana was synonymized with Cleta as a junior synonym. Nonetheless, authors (Tomaszewska & Szawaryn 2016) were not aware that the name Cleta is preoccupied. It appeared that Duponchel (1845) established the genus Cleta in the family Geometridae (Lepidoptera) that makes Cleta Mulsant (1850) a junior homonym. Therefore, we propose here Afrocleta nom. nov. as a replacement name for Cleta Mulsant, 1850.
