dc.description.abstractThe genera <i>Chambersiella</i> and <i>Geraldius</i> (Nematoda) are nearly morphologically identical, differing primarily in female ovary number: <i>Chambersiella</i> was described as monodelphic, while <i>Geraldius</i> was diagnosed as didelphic. This note reevaluates the validity of that distinction, incorporating original descriptions and a previously overlooked archival note from N. A. Cobb. Field observations failed to recover monodelphic specimens, even in type localities. We propose synonymizing <i>Geraldius</i> with <i>Chambersiella</i>, supported by Cobb's archived observations and consistent morphological evidence.en
