Rivision of Pelagic Ostracods of the Subfamily Archiconchoecinae

Abstract

Pelagic ostracods of the subfamily Archiconchoecinae have been revised. Their single genus Archiconchoecia Mi.iller, 1894 has been divided into seven genera and two subgenera: Archiconchoecia (Archiconchoecia) Mi.iller, 1894, Archiconchoecia (Archiconchoecidia) subgen. nov., Archiconchoecilla gen. nov., Archiconchoecissa gen. nov., Archiconchoecemma gen. nov., Archiconchoecinna gen. nov., Archiconchoecetta gen. nov. and Archiconchoecerra gen. nov. Six new genera, a new subgenus and seven new species have been described in detail. A redescription was made for the additional known taxa, Archiconchoecilla maculata (Chavtur, 1977) and Archiconchoecemma orientalis (Chavtur, 1987). A detailed synonymy and data on distribution are given for all species, and for some species morphological comments also have been added. Keys were elaborated for all taxa. The distribution of ostracods of the subfamily Archiconchoecinae has been discussed.
