Diagnoza Minute conch with flat flanks and radially running sinuous internal thickenings; suture with angular flank lobe. Porównanie — Sobolew’s (1914) Oma-monomeroceras (Cheiloceras) subpartitum Münst. angustivaricatum from the Lower Łagów Beds and O. (Ch.) s. lativaricatum, from both the Lower (the holotype) and Upper Łagów Beds apparently represent morphotypes of the same species. Becker’s denomination of the neotype of Ch. subpartitum changed its traditional meaning and one of the names used by Sobolew offers a replacement. Perhaps also his Oma-monomeroceras (Aganides) atavum from Sieklucki’s brickpit belongs here or to Ch. discoidale. Autekologia Występowanie geograficzne Jabłonna, Kadzielnia, and Łagów-Dule. Zasięg czasowy K. crepida Zone. Materiały muzealne ZPAL: 2 specimens. Literatura Dzik, J. 2006. The Famennian "Golden Age" of conodonts and ammonoids in the Polish part of the Variscan sea.
