Explanation of Names
Scutocoxifera Dreyer & Wägele, 2002
Most members of this clade have their coxae forming plates fused to the underside of the body.(1) In Asellota all coxae are free as small rings around the base of the legs and in Microcerberidea some groups have the front 4 legs with ring-like coxae and the posterior 3 legs with plate-like coxae.
The vast majority of isopods belong under this group. In terms of groups that people will likely encounter, all terrestrial and most marine species are part of this group, while most freshwater species (Asellotes) and some marine species (such as Jaera albifrons) are not.
