Marcus E 1952 (citation)- Epicytium with nuclei entirely sunken in all the anterior region of the body eliminates this as K. belca. K belca has intra-epithelial nuclei. Discussion of K. belca and K. brevicauda. Dorjes J 1968 (citation)- p 97 defines, lists as type K. brevicauda. 2 species K. brevicauda Marcus 1950 and K belca Marcus 1952.
