Original Description

Larcarida with lentelliptical spongy shell, containing a central cavity of the same form, without medullary shell (without radial spines).

The genus Spongolarcus differs from Cenolarcus (its probable ancestral form) only in the development of spongy framework forming the wall of the hollow lentelliptical shell. It corresponds, therefore, to Plegmosphaera among the Sphaeroidea, and to Spongellipsis among the Prunoidea. From these two similar spongy Sphaerellaria it differs in its characteristic lentelliptical form, with three dimensive axes of unequal length.

Etymology:
Greek spongolarcus = spongy basket"
