Systematics
Physetocaris microphthalma was previously placed in its own family (Physetocarididae) and superfamily (Physetocaridoidea).[1] Molecular phylogenetic analysis has revealed that the species actually belongs within the family (Pandalidae) and superfamily (Pandaloidea).[2] The genus and species were described in 1940 by Fenner A. Chace Jr.
Description
Distribution
P. microphthalma is rare, with only 35 specimens counted in a 1985 review.[3] Although very poorly known, the distribution of Physetocaris appears to be very wide. In addition to specimens from both western and eastern parts of the Atlantic Ocean,[4][5] it has been found in the southern Pacific Ocean.[6]
