Female (from 25°28'S, 44°57'W): 12-13, habitus (dorsal and lateral, respectively); 14, urosome (dorsal); 15, genital complex (ventral); 16, A1; 17, A2.

Distribution map of Comantenna recurvata by geographical zones
|
| | | | Loc: | | | off Woods Hole, Brazil (off Sao Paulo).
Type locality: 39°45'N, 70°34'W. | | | | N: | 2 | | | | Lg.: | | | (200) F: 4-3,72; (234) F: 3,5; {F: 3,50-4,00} | | | | Rem.: | hyperbenthic (± 1800 m).
For Alvarez (1986, p.862) the synonymy with Comantenna crassa cannot be retained on the contrary to Bradford & Jillett (1980). The two species are similar, differing only in the number of setae on the following appendages: A2 endopod, Md palp, Mx1, and 1st and 2nd basipods of Mxp.
Compare the selected characters of the different species in Comantenna females in Markhaseva & al. (2017 a,, Table 1, p.29). | | | Last update : 21/12/2017 | |
