Cohnilembus Kahl, 1933
Synonym; Lembus Cohn (ref. ID; 1618)

[ref. ID; 2014]
Small to large (30-150 um long) elongate ciliate, many species having an elongated neck-like region. The peristomial area extends from the apical pole down towards more or less the middle of the body although in some species it may only reach a third to the body length. There are 2 membranelles running along the right edge if of the peristome although one may be difficult to see. Somatic ciliation in 9 or 10 longitudinal rows, and there is a caudal cilium present. Contractile vacuole is terminally located. 1 or 2 macronuclei which are ovoid and sub-equatorial.
