Eudorella Norman, 1867

Genus Eudorella Norman, 1867 View in CoL

Diagnosis: Pseudorostrum directed dorsally in both male and female; antenna 1 geniculate between peduncle article 2 and 3; male antenna 2 with brush of setae on anterior margin of peduncle articles 4 and 5; male antenna 2 flagellum extending nearly to end of pleon; female with exopods on pereiopods 1–3; male with exopods on pereiopods 1–4; pereiopod 2 article 3 lost; uropod endopod 2 articulate; male with 2 pairs of pleopods. ( Watling, 1991).

Remarks: The most important characters for discriminating the species of the genus Eudorella are, according to Barnard & Given (1961): style of serration along the anterior carapace margin; articulation of the apical seta of the uropod endopod if it is fused or articulate; length relation between the uropod endopod and exopod; form and/or serrations of anterior sinus of carapace (antennal notch).

According to Watling (1991) and not mentioned in Barnard & Given (1961), important characters are: A1, accessory flagellum length and width compared with main flagellum; length proportion between peduncle articles 2 and 3; pereiopod 2 article 5 relative length to article 4; presence or absence of a long plumose seta on peduncle distal end.
