Description from Südkamp 2017, p. 111: " Cup very tall and narrow cylindroconical. The long, slender, non-pinnulated arms divide three to four times isotomously abouve the fourth to fith primibrach. The anal sack is narrow and elongate and composed of several vertical rows of plicate plates. The appearance of the stem is reminiscent of a string of pearls. Only the proximal part consists of short, pentagular elements."
