, are in a marginal position on gnathopod 2 and pereopods 3–6, which is an unusual position for these organs in the bogidiellids. There is no existing hypothesis about the exact function of these “organs,” except that they could play a role in tegumental respiration. The fact that they are not always present in the bogidiellids, argues against a phylogenetic significance, and instead suggests only a functional importance. In support of this suggestion is the presence of analogous structures in several other subterranean amphipod families, such as the ingolfiellids and paracrangonyctids.

. The degree of fusion of the coxal endite appears to follow a graduated trend or pattern, leading us to regard the presence of this structure in the AfroArabian group as a plesiomorphic character state, with the more fused condition representing increasing reduction phases that tend toward an apomorphic state. Whether or not this actually represents a trend from primitive to advanced for this character is questionable for the moment and will remain unclear until the maxillipeds of specimens in the other bogidiellid genera are carefully reexamined.
