Cherkesova (2007) reassigns two taxa, "radiata" and "omaliusi", that Nalivkin had placed in Camarotoechia, to Sinotectirostrum as a new combination for a species and a subspecies respectively. The type of Camarotoechia is perhaps Atrypa congretataConrad, 1841[verification needed]. The species †Camarotoechia elegans[3] is from the Ordovician and Silurian of the Siberian Platform. It includes one subspecies Camarotoechia elegans forma ramosa.[3]
