Bathycalanus eximius Markhaseva, 1983 (F) | |
| | | | | | | Ref.: | | | Markhaseva, 1983 (in Brodsky & al., 1983, p.197, Descr.F, figs.,F); Bradford-Grieve & al., 2017 (p.129, Descr F, Rem.) |  issued from : K.A. Brodsky, N. V. Vyshkvartzeva, M.S. Kos & E.L. Markhaseva in Opred. Faune SSSR, 1983, 135 (1). [p.196, Fig.87]. Female: habitus (dorsal and lateral, respectively); R, forehead and rostrum; Mx2; Gn, genital segment (dorsal, lateral and ventral: respectively Gn1, Gn2 and Gn3. Nota: Genital segment barrel-like. Complement from Bradford-Grieve & al. (2017, p.129): - Forehead, in dorsal view, with low prpjection bearing pair of small spine-like processes. - In lateral view, posterior corners of pediger 5 symmetrical, rounded, but slightly pointed in dorsal view. - Genital double-somite markedly swollen and symmetrical in dorsal view, wider than long, with lateral surfaces ornamented with large spinules. - A1 extending beyond caudal rami by 4-6 segments; anterior and posterior borders of ancestral segments XVI-XXI smooth.

Morphological characters after identification key of Bathycalanus females and males. Compare to other species of genus. Main characters identification after species key : 1 - Mx1 praecoxal endite without setae. 2 - Anterior margin of head with 2 very small spine-like processes. 3 - P1 exopod segments 2 and 3 separate; 4 - Pedigerous somites 4 and 5 without laterally extended lappets; Genital double not angular shaped. 5 - Genital double-somite very swollen in dorsal view, decorated with spinules. (male unknown).
