Setoisenoton Mesibov, 2010, n. gen.
Setoisenoton, n. gen. Type species. S. pallidus, n. sp., here designated. Diagnosis. Small H+ 19 dalodesmids (ca 5 mm long) with long, straight, non-fused gonopod telopodites ending in a two-process claw in the longitudinal plane, with the prostatic groove terminating in the anterior process.
