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).
