| Sumario: | The literature on <i>Dobrodgeiceras</i> is reviewed and the known Peruvian specimens are re-examined. <i>"Sphaeroceras Broggianus"</i>, Lissón, 1937, with which <i>D. benavideri</i> Nikolov, 1965, is synonymized tentatively, is not a Bajocian sphaeroceralid as previously believed and is placed in the Valanginian genus <i>Dobrogeiceras</i>. The Peruvian species resembles <i>D. wilfredii</i> (Karakasch) from Bulgaria and France in the absence of presence of ventral tubercles on the adult body chamber; these tubercles are therefore not regarded as taxonomically significant. |
