(1) The structure is radial and lobate with a series of narrow and wide lobes.(2) Among armadillos, some groups reduced their dentition in response to myrmecophagy and some acquired lobate teeth and accentuated differences in hardness of dentine types.(3) The dynamic and unstable nature of this regulatory loop best explains the lobate and asymmetric colony margin of the SA type.(4) At the distal end, the axis is turned upward and lobate and is divided into five lobes.(5) The median lobate structure, formed by fusion of the two median muscle boundaries of the true lobes, may be extended away from the two lateral lobate structures (which are the lateral muscle boundaries of the true lobes).(6) Adults of both groups have complex glabellar lobation .(7) The development of lobation in later growth stages is mainly expressed in the widening and deepening of sulci.(8) As differences in the direction of the dorsal node and the style and relative length of lobation are the key criteria used to differentiate hipponicharionid genera, it is appropriate to erect a new genus for this Antarctic bradoriid.(9) Key characters in the genus are ovary lobation , features of the stigma, anther/filament ratio, leaf shape, and whether or not the leaves are sessile or petiolate.(10) The valves of beyrichonids, however, are less inflated and lobation is subdued in comparison to hipponicharionids.
