Rem.: 5 G. : Acartia, Acartiella, Paracartia, Paralabidocera, Pteriacartia.
The genus Paracartia is not always accepted by all the authors.
For Barthélémy (1999 has, p. 59) the genital structures do not justify the creation of 6 sub-genera. The species of the various sub-genera are distributed in a variable way in 3 of 4 subgroups of species corresponding to four variants of the model acartiidae (cf. Fig.5, Plan 9). Account was already held by the absence of significant morphological criteria of distinction of the sub-genera, the characteristics of the genital area do not justify more to keep the sub-genera.

Rem.: In a genus revision, Steuer in 1915 establishes two subdivisions based on the presence/absence of rostral filaments (Arostratae et Rostratae), but later Bowman (1965) when studying a population of A. liljeborgi demonstrates that the rostral filaments can be present or absent. The environmental conditions, notably the salinity, could be responsable for this fact.
It is probable that other morphological characters show a certain variability like the spinulation of the abdomen, the structure of the P5. Various anomalies have been shown by Brylinski (1984, p. 961)
The genus divides currently into 6 sub-genera: Acartia (Planktacartia ), Acanthacartia , Acartiura , Euacartia , Hypoacartia , Odontacartia, contested by Barthélémy (1999, p.868; 1999 a, p.59, scheme 9) after analysis of the genital structures. Among the majority of species, we can distinguish two main groups, based on the external morphology of the genital area on one hand, and the seminal duct morphology on the other. The first group includes ten species, viz., A. clausi, A. hudsonica, A. omorii, A. longiremis of the subgenus Acartiura, A. bifilosa, A. chilkaensis, A. italica, A. levequei, A. tonsa of the genus Acanthacartia, and A. lilljeborgi of the subgenus Odontacartia, exhibing a compact external area, with well-defined structure for each of them. All exhibit a very homogeneous configuration of their internal area with seminal ducts in characterisytic loop-like form. Accorfding to Steuer (1923), this loop is visible in ventral view after clearing the specimens. The duct seems less voluminous only in the subgenus Acanthacartia species. The similitude in the organization of the genital structures af all these species confirms the closerelationship between the subgenera Acartiura and Acanthacartia. Thus, the morphology of the genital complex does not justify the distinction of two subgenera. The second group comprises A. danae, A. negligens of the subgenus Acartia, A. amboinensis, A. japonica of the subgenus Odontacartia and A. southwelli of the subgenus Euacartia; these species offer a fragmented external area with ventrolateral genital slits, and seminal ducts, simple bend-shaped opening in the proximal zone of the egg-laying ducts, as in the precedent group. Therefore, the genital anatomy does not justify the distinction between the different subgenera.

Rem.: Genus defined by Sewell (1914) with for species type: Acartia kempi Sewell, 1914. Considered by various authors as a sub-genus or a new family.
For Barthélémy (1999 a, p. 59) this genus has to constitute to him only a family. The species present a genital area of diaptomoid type deprived by opercule and by receptacle seminal, which distinguishes them from all other species of the family of Acartiidae possessing a genital model of area characterized well by the constant presence of receptacles and pores copulators neighboring to gonopores. We can also observe the other morphological characters: the length of the branches of the caudal rami, the shape flattened by the antennula, the biramous P5. These characters differentiate all the species of the genus of the other Acartiidae, with the exception of Acartiella kempi, only species of the genus presenting an antennule similar to that of Acartia (Sewell, on 1918).
According to Barthélémy (1999, p.868) the morphology of the external genital area and the absence of seminal receptacles very clearly isolate species of the genus Acartiella Sewell (1914), the validity of which is thus confirmed. Bradford (1976) pointed out that Acartiella should remain in the Acartiidae family especially because the exopods of P2-P4 are devoid of articulated outer edge spines, as in the other Acartiidae.

Rem.: Considered as a subgenus by T. Scott, Steuer, then later as a genus by Sars (1904b).
For Barthélémy (1999a, p. 59) the organization of the external genital area , separated, in very lateral side and posterior genital splits, could constitute an important characteristic of the genus.

(4) Paralabidocera Wolfenden, 1908
Ref.: Wolfenden, 1908 (p.26); Vervoort, 1951 (p.148, Rem.); Bradford, 1976 (p.163); Brodsky & Zvereva, 1976 a (p.233-34, Rem.); Razouls,1982 (p.620); 1993 (p.307); Mauchline, 1998 (p.95); Barthélémy, 1999 (p.869: Rem.); 1999 a (p.34); Bradford-Grieve, 1999 b (p.227, Déf., Rem.); Boxshall & Halsey, 2004 (p.52)
Rem.: Type: Paracartia antarctica Thompson,1898. 3 spp.
For Barthélémy (1999, p.869) the sole examined species presents a fragmented area with two lateral genital slits, but internally there is no seminal duct and the receptacle seems to open distally in the egg-laying duct. The presence of paired genital orifices situated on both side of the genital segment is a constant character of the genus. The three species of the genus therefore present genital structures clearly differing from those of the Pontellidae. Thus, in spite of the resemblance with the genus Labidocera (Pontellidae), the comparison with the genital structures in Pontellidae (Barthélémy & al., 1998) confirms that the genus must be referred to Acartiidae.
