Distribution map of Chiridiella bispinosa by geographical zones
Loc:
Gulf of Mexico, W Indian.

Type locality: 27°08'N, 89°55'W.
N: 2

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.
