摘要：
The genus Djanaliparkinsonia Kutuzova, 1975 was originally described as an endemic subgenus of the genus Parkinsonia (family Parkinsoniidae of the superfamily Perisphinctoidea) from the Upper Bajocian (middle member of the Degibadam Formation) of the Gissar Range (Uzbekistan). A new species D. alanica sp. nov. is established from the Upper Bajocian Garantiana garantiana Zone (upper member of the Djangura Formation) based on occurrences in the Northern Caucasus (Karachay-Cherkessia). Macroconchs and microconchs of the new species are described from the two localities on the Kuban and Kyafar rivers. Djanaliparkinsonia sp. is identified from the lower subzone of the Parkinsonia parkinsoni Zone of the Kyafar River. The species composition and geographic range of Djanaliparkinsonia are expanded: a species previously described from Germany as Garantiana bentzi Wetzel, 1954 also assigned to the genus. The genus Djanaliparkinsonia is assigned to the subfamily Garantianinae of the family Stephanoceratidae (superfamily Stephanoceratoidea).
