The type material of Scotiella Delo 1935 is redescribed and the generic diagnosis emended to include trilobites in which the anterior and median lateral glabellar furrows are both strongly and poorly defined. The genus now embraces the species Scotiella logani (Hall 1860), S. conservatrix (McLearn 1924) new combination, S. minor (M'Coy 1851), S. samsonowiczi Tomczykowa 1962b and S. opatowiensis Tomczykowa 1962b.
