Abstract
A new species, Oneirodes logachevi sp. nova, is described. It is closely related to O. macrosteus but differs in the presence of a median escal appendage, a tall terminal papilla and the details of its pigmentation, the lack of distal branching of the anterior, anterolateral, and posterior escal appendages, but the presence of short secondary branches along the entire length of the posterior appendage. Oneirodes micronema, previously known only from two specimens of the type series from the Banda Sea, is recorded for the first time in the Atlantic Ocean. The new specimen differs from the type specimens primarily in the presence of branches on the anterolateral and median escal appendages, which may be associated with the individual variability.
