Family Proporidae Sokolov, 1949

Genus Acdalopora Bondarenko, 1958 Type species: Acdalopora sokolovi Bondarenko, 1958 , Upper Ordovician, Chu-Ili Mountain region, southern Kazakhstan.

Remarks.—We follow the diagnosis of Acdalopora by Hill 1981). This genus was considered by Young and Noble 1990) to be synonymous with Propora Milne-Edwards and Haime, 1849 , because he believed that well-developed septal plates typical of Acdalopora were within the normal variation of Propora . Given the taxonomic importance of septal plates, we consider Acdalopora as a valid genus, as suggested by some authors (e.g., Hill 1981; Bondarenko 1992).

Forms closely similar to Acdalopora include Wormsipora Sokolov,1955 ,and Kimilites Sladkovskaja,1987 . Wormsipora is distinguished from Acdalopora by possessing entirely tubular coenenchyme, incomplete tubular walls, and septal spines. Kimilites differs in having better developed coenenchyme and septal spines.
