The Nodoconchiinae, a new subfamily of Cytheridae (Crustacea, Ostracoda)
The new subfamily Nodoconchiinae of the Cytheridae Baird is erected to accommodate three genera: Austrocythere Hartmann, 1989a, Nodoconcha Hartmann, 1989a and Ectonodoconcha gen. Nov. Austrocythere seems to be known only from the type species A. reticulotuberculata Hartmann, from its type locality i...
