Description from Südkamp 2017, p. 142: "Ophiurina and 'Eschenbachia' are the smallest ophiuroids of the Hunsrück Slate. The round disc is covered with a finely granular skin. The margin of the disc consists of 15 rod-like plates, of which every three of them are lying interradially. The marginals are connected to the second arm segment (personal information F. Hotchkiss, 2016). the vertebral halves are arranged in opposing pairs. The largest elements of the arm skeleton are the curved laterals, which bear a row of small spines of unequal length. They are orally touching across the midline of the arms. The five slender arms taper in their first halves evenly and the laterals become long slender rods towards the extremity of the arms"
