Strophomenide and pentameride brachiopods are described from shelfal environments (BA 3) flanking islands of the Macquarie Arc during the Late Ordovician (latest Sandbian to early Katian stages). Most of the strophomenoid genera recognized are new, monotypie, and hence endemic, although the occurrence of a new species of Shlyginia is indicative of affinities with Kazakhstan. Taxa described include the strophomenid Geniculomena barnesi gen. et sp. nov., the rafinesquinid Testaprica rhodesi gen. et sp. nov., glyptomenids Resupinsculpta cuprafodina gen. et sp. nov., Paromalomena zheni sp. nov., and Platymenal sp., and the plectambonitoid Shlyginia rectangularis sp. nov. Review of the generic assignment of Oepikinal walliensis Percival, 1991 suggests that this species is better placed in Murinella Cooper, 1956. Relatively rare pentameride brachiopods are represented by only a few specimens, including an unnamed species of Parastrophina, and a species tentatively referred to Eoanastrophia.
