Genus Myrmekioderma Ehlers, 1870

Definition: Heteroxyidae with a detachable ectosomal skeleton consisting of smaller (acanth-)oxeas in brushes perpendicular or paratangential to the surface, supported by larger choanosomal (acanth-)oxeas, strongyles or styles forming a slightly compressed halichondroid reticulation in the central portion of the choanosome and a more cavernous peripheral skeleton of oblique spicule tracts, with wispy trichodragmata of raphides in one or two size classes dispersed throughout the skeleton ( Hooper, 2002).
