Diagnosis Gephyrocrinus with crown length <30 mm. No lateral wings or spines on proximal brachials. Arm pattern 1+2 3 4 5+6 7+8 9+10…(87%); brachial triplets almost always present; free brachials rare. First pinnules usually on Br4. Wr/Wb 1.2-1.8. Pinnules stout, relatively rigid, <10 per arm side. Pinnule socket on distal half of brachial. Pinnule cover plates rarely conspicuous on proximal and middle pinnules, lanceolate on distal pinnules. Theca unornamented. Tegmen reaching Br4–5 (Br6–7 in largest specimens). Usually 12-15 tegminal plates per interradius (rarely to 18), smooth and convex. Anal cone subconical, taller than oral cone. Orals well-developed, convex and smooth. No angle between radials and basals; no ornamentation; base usually flanged. Proximal columnals polygonal, without knobs. Crenular units in symplexies 6–8, of 1–2 crenulae. Distal syzygies with radial to weakly labyrinthic pattern; crenulae less developed. [details]

Distribution NE Atlantic from N slope of the Bay of Biscay to Madeira and from the Canary Islands to the Mid-Atlantic Rise. Depth range: (?1,360?) 1,420-1,968 m. [details]
