Distal part of lorica curved at angle of approximately 20о with respect to longitudinal axis of body. Distal aperture moderately sloped, with even edges. Stalk consisting of three parts – exostyle, mesostyle and endostyle (Jankowski’s 1989 terms). External part of stalk (exostyle) relatively long and slender, provided with small basal disk at point of attachment to substrate. Mesostyle (stalk inside exotheca) wider than exostyle, longitudinally striated, and located in cone-shaped tubular passageway through base of lorica. Zooid attached to bottom of endotheca by low, wide disc (modified endostyle).

Lorica with single zooid. Cell body elongate, with prominent, annular ridge located slightly aboral to midpoint of body. Pellicle with distinct transverse striations. Peristomial disc large, prominent. Peristomial lip wide, extending well beyond maximal body width and unequal in thickness. Ventral side of peristomial lip near entrance to infundibulum extremely thick (twice as thick as dorsal side), with noticeable sulcus running transversely across it. When ciliate contracts, distal part of cell body bends toward concave side of lorica wall, and swollen edge of peristomial lip covers rest of cell body. Contractile vacuole located beneath peristomial lip near ventral wall of short infundibulum. Macronucleus elongate and ribbon-like with slightly recurved tips, oriented along longitudinal axis of body. Micronucleus located near aboral end of macronucleus. Adoral zone of cell body protruding as much as 37 µm from lorica when expanded. The telotroch is symmetric, elongated and cylindrical, without lamellar ring as in
