Version 1 : 2 oct 2002. http://www.crustacea.net/crustace/calanoida/index.htm  | | Rem.: | 4 G.: Disco, Paradisco, Prodisco, Pertsovius. For Andronov & Kosobokova (p.38-39) several species within the family Discoidae are very similar to each other; Park (1970) and Schulz 1993) noted their close similarity, which could warrant their placement within a unique taxonomic clade. The discovery of three additional species affiliated with this clade in the Arctic Ocean further warrants erection of a distinct genus: Pertsovius comprising henceforth 7 species. | | | | (1) Disco Grice & Hulsemann, 1965 | |

In 1967, the male of D. inflatus was described as well as a second male not identified to one of the known species. The authors regard this genus as belonging to the family Augaptilidae, followed by Matthews (1972). Fosshagen (1967) estimates that the characteristics of the females hardly allow a such a classification. Gordeeva (1974 a and b) described several new species and creates in 1975 two new genera which are included in the new family of Discoidae. Andronov & Kosobokova (2011, p.38) transfer 4 species earlier in the genus Disco within a new genus Pertsovius which includes henceforth 7 species. Total (2011): 16 spp. + 1 unspecified. | | | | (2) Paradisco Gordeeva, 1975 | |
| | Ref.: | Gordeeva, 1975 (p.192); Razouls, 1982 (p.524); 1993 (p.306); Schulz, 1993 (p.205); Mauchline, 1998 (p.73: F; p.74: M); Bradford-Grieve,1999 b (p.69, Déf.); Boxshall & Halsey, 2004 (p.110); Vives & Shmeleva, 2007 (p.286, spp. key) | | Rem.: | 4 spp. | | Remarks on dimensions and sex ratio: | | The average lengths of the females is 0,533 mm (n= 4; S= 0,084; Cv= 0,158) and of 0,520 mm for the males (n= 3; S= 0,115; Cv= 0,221). The ratio lengths (M/F) is 0,994 or 94,4% (n= 3; S= 0,052; Cv= 0,055). | | | | (3) Pertsovius Andronov & Kosobokova, 2011 | |
