Aporogona crenulata (L atzel , 1884) according to C ook 1895. L atzel 1884 described the species after 1 immature individual. Only Attems (1895, 5/77) mentioned new material under this name, V erhoeff (1896, 122/35) only listed this name. The species was not mentioned in later literature. Since the locality data of Latzel's and Attems' specimens were identical with those for Polyphematia moniliformis (L atzel , 1884) (see below), it seems that Cr. crenulatum might be the juvenile form of the latter species (G ruber in litt. 2001).
