The abundant and diverse beyrichioid ostracod faunas preserved in Silurian and Devonian silisiclastic strata of the Lachlan Orogen in southeastern Australia include specimens of the genus Bungonibeyrichia. Bungonibeyrichia copelandi sp. nov. is proposed for the fossil material, originally misidentified at species level, on which the description of this genus was based. The new species is nominated as the type species for Bungonibeyrichia in accordance with Article 70.3 of the International Code of Zoological Nomenclature. Bungonibeyrichia is distinguished from other beyrichioid genera on the basis of a distinctive combination of lobe, velum and crumina features. Tamara T.A.
