Pour Markhaseva (1996, p.8) cette famille ne comprendrait que 26 genres (avec le nouveau genre Parabradyidius); Gaidius est synonyme de Gaetanus; Wilsonidius est considéré comme un synonyme de Chirundina; Gaidiopsis est insuffisamment décrit et l'espèce type perdue; Pseudotharybis est intermédiaire entre cette famille et les Tharybidae; Valdiviella pourrait constituer le type d'une famille nouvelle.

Phylogenetic trends within Aetideidae (Copepoda, Calanoida).
Ac..... : asymmetry.

Three main phylogenetic trends within Aetideidae are revealed: The first is retraced for Aetideus, Paivella, Aetideopsis, Badyidius, Chiridius. Among them Aetideus and Paivella are considered as most specialized; the second; Gaetanus, Pseudochirella, Chirundina, Chirundinella, Undeuchaeta, Euchirella and Batheuchaeta, the later: two genera are the most specialized; the third trend of Aetideidae evolution is represented by Chiridiella which may be a good example of feeding specialization.
Epibenthic aetideids show weak resemblance with pelagic ones and are not referred to any of the three mentioned trends, but altogether might be characterized by having in their morphology a mosaic combination of primitive and progressive features.
Aetideidae developed by expansion of nearly all pelagic vertical zones and by broadening of feeding types from the mixed type of feeding to predation (Pseudeuchaeta) or sucking predation (Chiridiella).

Latitudinal zones of the World Ocean pelagial.

The geographical subdivision of the pelagic is given according to Nesis, 1982 (in Zoogeography of the World Ocean: comparison of the pelagic zonality and the shelf regional subdivision. In: O.G. Kussakin ed. Marine Biogeography. Nauka, Moskva: 114-134).
The similarity of faunas in the different geographical zones of the world Ocean was examined with the use of Sorensen's index of similarity (IS) and Simpson's index of inclusion (II) of less diverse fauna into the richer one.

Four types of aetideid copepod distributions are denoted:
1 - Cosmopolitan genera: 7 genera, of which Euchirella is only absent in the Arctic Ocean. The mainly pelagic genera: Gaetanus, Pseudochirella, Euchirella, Aetideopsis, Chiridiella, Chiridius, Pseudeuchaeta.
2 - Tropico-boreal genera: Three pelagic genera Aetideus, Chirundina, Undeuchaeta and two benthopelacic genera Bradyidius, Comantenna.
3 - Genera found within tropical limits: Two pelagic genera Chirundinella, Paivella and five benthopelagic genera Crassantenna, Lutamator, Mesocomantenna, Paracomantenna, Sursamucro.
4 - Benthopelagic genera: Three benthopelagic genera are registered within the limits of the Arcto-boreal Jaschnovia is found in both arctic and boreal zones; Bradyetes is known from the boreal Atlantic and Azygokeras from the boreal Pacific.
The pelagic genera demonstrate wide distributions, whereas 8 benthopelagic genera are mostly endemic.

Comparison of faunas:
The tropical Pacific aetideid fauna is the richest with 98 species, followed by the tropical Atlantic fauna with 73 species, and the tropical Indian Ocean fauna with 50 species.
nearly equal in species number are the boreal Atlantic (57 species) and boreal Pacific (53 species) faunas.
The Subantarctic fauna (Not) includes 30 species and the Antarctic and Arctic faunas contain 29 and 14 species respectively.

The results of the analyses of the total aetideid fauna show a high degree of similarity between tropicalAtlantic, tropical Pacific and tropical Indian ocan faunas (IS = 56 to 62 %) and between each of these fauna with fauna of boreal Atlantic (IS = 54 to 58 %)
The degree of similarity between Subantarctic and Antarctic faunas is also high (IS = 61 %).
An aetideid fauna of the upper 500 m layer is nearly absent in Polar basins (see fig.6). Few aetideid species occur in the upper layers in Polar basins. Nevertheless they are typical of deeper layers in the other regions of the Wiorld Ocean and it are most likely meso-, bathy-, or meso-/bathypelagic species.
The tropical faunas are significantly similar to each other (IS = 63 to 77 %) and to the boreal Atlantic fauna (IS = 67 to 78 %). The latter is also similar to the Subantarctic fauna (IS = 57 %).
The faunas of the tropical Atlantic and Indian Oceans are related to the tropical Pacific fauna (for the tropical Atlantic II = 81 %, the latter includes the total fauna) and the boreal Atlantic fauna is related to the tropical faunas with II values of 73 % to 93 %.
The fauna of the Subantarctic is totally included into the boreal Atlantic fauna.
The boreal Pacific fauna is poor in comparison to tropical faunas , and in this respect it is separated more clearly than the boreal Atlantic fauna.
The similarity between the boreal Pacific and boreal Atlantic faunas is weak; and similarity is even smaller between boreal Pacific and Subantarctic zones.
The deep water aetideid fauna exists in Polar basins (10 species in Arctic and 22 species in Antarctic zones (see fig.7). The similarity between these faunas is moderate (IS = 38 %), and due to the presence of the bipolar species (Aetideopsis minor, Pseudochirella batillipa, P. spectabilis), and the cosmopolitan species Gaetanus brevispinus, G. tenuispinus.
The arctic fauna is poor and has weak similarity to boreal and tropical faunas (IS = 21 to 24 %)
The boreal faunas of deep water aetideids are rather similar (IS = 52 %). The boreal Atlantic deep water fauna is related to the boreal Pacific fauna. It is very possible that boreal faunas originated from tropical faunas, but the boreal Pacific fauna probably is older than the boreal Atlantic. The boreal Pacific deep water fauna has higher similarity with the deep water aetideid fauna of the tropical Pacific (IS = 51 %) than with the upper layer aetideid faunas.
The similarity of the boreal Pacific fauna with the tropical Atlantic and Indian Ocean faunas, is weak and this is comparable with the above mentioned similarity for the upper layer aetideids. The distribution of deep water aetideids showed that they have significantly more similarities than the faunas of the upper layers.
The fact that the tropical Pacific fauna is the richest suggests that it is the most ancient among aetideid fauna.

Seration sometimes reduced or modified, only 2 outer spines on distal exopodal segments of P2 to P4 in Senecella calanoides Juday. Terminal spines on exopods of P2 to P4 with conspicuous dentate outer margin.

Right leg typically biramous with up to 3-segmented exopod and 1-segmented endopod, rarely absent as in Aetideus. Left leg biramous with up to 3-segmented exopod and 1-segmented endopod. P5 highly variable; both may be uniramous, lacking endopods. Endopods rarely 2-segmented as in Parabradyidius angelikae Schulz & Markhaseva, Bradyetes matthei Johnnessen, Bradyidius arnoldi Fleminger and Comantenna brevicornis (Boeck).
- Eggs retained in paired multiseriate sacs, at least in some species; rarely in uniseriate sacs as in Euchirella pseudopulchra Park.
