Description from Südkamp 2017, p. 118: " The cup is small and the crown elongate ovoid,. The uniserial robust arms divide after the third primibrach isotomously. In total, there are at least three bifurcations. The amount of brachials between the higher divisions increases. The round arms rejuvenate especially after the third division and form long, thin whip-like terminations. As in Codiacrinus these terminations are often enrolled. The upper round stem is wide and consists of low elements. The distal stem consists of alternate high elements. Many specimens have medially and distally long cirri, which rise on both sides and can divide more times."
