NEOCYCLOPS Gurney 1927; Petkovski 1986 (syn.Eurycyclops Sewell, 1949; Neocyclops (Neocyclops) Gurney, 1927; Neocyclops (Protoneocyclops) Petkovski, 1986; Pareuryte Herbst, 1952)

The genus Neocyclops Gurney, 1927, sensu Petkovski, 1986, includes 24 species, widespread in coastal, surface and subterranean (anchialine), habitats of Northeast and Tropical Atlantic, the Mediterranean, the Black and Red seas and the Indian (Australia) and Pacific (Papua, New Guinea) oceans, with an endemism index of about 95%.

Petkovski (1986) splitted the genus into two subgenera according to the number of exopodal segments of the male fifth leg. Particularly, species with male exopod of leg 5 4-segmented (plesiomorphic state ?) are grouped in the subgenus Protoneocyclops, and species with the same exopod 3-segmented (apomorphic state ?) are included in the subgenus Neocyclops s. str.

The subgenus Protoneocyclops comprises seven species: P. mediterraneus (Kiefer, 1960); P. stocki Pesce, 1985; P. papuensis Fiers, 1986; P. herbsti Petkovski, 1986; P. wellsi Petkovski, 1986; P.geltrudeae Pesce & Galassi, 1993; P. ferrarii Rocha, 1995 . The subgenus Neocyclops embraces six species: N. salinarum (Gurney, 1927); N. remanei (Herbst, 1952) ; N. medius Herbst, 1955 ; N. vicinus (Herbst, 1955) ; N. affinis (Plesa, 1961); N. petkovskii De Laurentiis, Pesce & Halse, 1997. In the following discussion the division of Neocyclops in the subgenera Neocyclops s.str. and Protoneocyclops will not followed.
