Diagnosis Original diagnosis by Hartman & Fauchald (1971: 53): "The body is short and linear, as is characteristic of the EXOGONINAE. Palpi are fused medially. The prostomium is broadly rectangular and lacks antennae. The first segment is a short, smooth ring with two pairs of blunt, tentacular cirri. The second segment is the first setigerous. The eversible proboscis is smooth, armed with a yellow, distally blunt tooth; the proventriculus is muscular and extends through about four segments. Parapodia are uniramous; setae are composite spinigers in superior position, and composite falcigers in inferior position; yellow acicula occur singly. Median and posterior parapodia have simple setae in uppermost and lowermost positions." [details]
Etymology The name of the genus Exogonita is derived from the name of the genus Exogone followed by the Latin suffix -ita, to denote the close relation between the two genera. [details]
