The new taxon Trochamijiella gollesstanehi is described; it is morphologically similar to, but phylogenetically distinct from, Amijiella, and is initially trochospiral; it is known from Iran, the United Arab Emirates and Oman, and is believed to characterise the Late Bathonian. Primary type specimens of Amijiella amiji and Haurania deserta are refigured for comparison and are believed to characterise Early Bathonian and older Jurassic strata. All three genera are reclassified and all are placed in the Biokovinidae Gušić, 1977.
