Porosia Jung 1942
Taxonomic concept of genus Porosia Jung 1942 Since the genus Porosia is not monospecific anymore, an expansion of the concept of this genus is required. Original description of the genus according to Jung 1942 is the following: Ahnlich wie Penardiella mit Porendurchbohrungen am Halsansatz. Doch fehl...
