Coleoptera Archostemata Ommatidae Zygadenia Baissa fossils


The term “generic complex” is proposed for 12 previously synonymized fossil genera of Ommatidae. Redescriptions of three species of the genus Notocupes are provided: N. excellens Ponomarenko, 1966, N. caudatus Ponomarenko, 1966 and N. vitimensis Ponomarenko, 1966, as well as a description of an elytron of a new species Zygadenia alexrasnitsyni sp. nov., from the Lower Cretaceous locality Baissa (Vitim River headwaters, Eastern Transbaikalia). The descriptions contain selected morphological characters that will be used in future redescriptions.
