Abstract: Genus Vanadis Claparede, 1870 Type species: Vanadis formosa Claparède, 1870 Diagnosis. Body long and slender. Prostomium not extending in front of eyes. Median antenna present or absent. Proboscis long, often with lateral horns. Three pairs of tentacular cirri arranged as 1+1+1. First one to seven parapodia (on segments 4–10) reduced and may lack chaetigerous lobes and/or chaetae. Dorsal parapodial cirri of one or two anterior segments enlarged in females to form a receptacula seminis. Normal parapodia of succeeding segments have foliaceous dorsal and ventral cirri and long chaetigerous lobes bearing one cirriform appendage. Apart from projecting aciculum, chaetae all compound spinigers. Segmental glands usually pigmented, may be underdeveloped in some segments; in the latter case, alternation of well-developed and underdeveloped glands forms a specific pattern.
