Colony exceedingly tiny, comprising just five autozooids and a central gonozooid, supported on a smooth, short pedestal. Typical cancelli lacking, but five small pores present, one basal to each zooidal aperture. Peristomes relatively thick-walled, with up to five short, blunt processes; all exterior surfaces of zooidal disc relatively coarsely granular. Brood chamber small, oval, its granular surface merging into that of the peristomes that surround it, the ooeciostome circular, smooth with a thin rim.

It is unquestionably the smallest cyclostome species known ― in fact the smallest calcified bryozoan known ― and the entire colony could easily fit inside an individual zooid of most cheilostome species; its individual zooids are smaller than the mature zooids of the interstitial ctenostome bryozoan
