Distribution map of Chiridiella bispinosa by geographical zones
|
| | | | | | Loc: | | | Gulf of Mexico, W Indian.
Type locality: 27°08'N, 89°55'W. | | | N: | 2 | | | Lg.: | | | (37) F: 2,5; (88) F: 2,52; {F: 2,50-2,52} | | | Rem.: | meso & bathypelagic. This species is related to C. subaequalis Grice & Hulsemann (1965), in the latter, Mx1 has 3 inner lobes and only 4 setae on the exopod and in Mx2 the heavy spines on the distal three lobes are equal in length. | | | Last update : 26/07/2018 | |
