title: Kuznetsovia, a new generic replacement name for Aenigma Kuznetsova, 1957 (Ostracoda) non Newman, 1836 (Coleoptera).
abstract: The generic name Aenigma was proposed by Kuznetsova (1957: 68; type species A. jucunda Kuznetsova, by original designation) for a new fossil ostracod genus from the Lower Cretaceous (Barremian) of Tegchaj, North-Eastern Azerbaijan, former USSR (Transcaucasia). However, this name is already preoccupied by a marine gastropod molluscan generic name Aenigma Newman (1836: 499), which is in active current use in zoology (Coleoptera: Carabidae). Besides this earliest generic name, a few homonyms were also known: Aenigma Amsel (1956: 288) [Lepidoptera], Aenigma Koch (in Martin & Chemnitz 1846: 1, unpaginated) [Mollusca], Aenigma Karsch (1878: 825) [Arachnida], Aenigma Strecker (1876: 122) [Lepidoptera].
