Newly collected phosphatised hexactinellid sponges are recorded from upper Cenomanian strata in the villages of Nezvys’ko and Rakovets’ of Podillia, south‐west Ukraine. Sponges from Nezvys’ko were first described in the late 19th century by Emil H. Dunikowski, but the original specimens appear to have been lost. Five neotypes of the hexactinellids Laocoetis maxima , Callodictyonella regularis , Plocoscyphia podolica , Toulminia polonica and Leiostracosia crassa are here designated. In addition, diagnoses of all species are provided and descriptions emended and supplemented.
