A small species with robust arms of proximal pattern 1+2 3 4 5+6 7+8 or 5+6 7; beyond Br6 series of successive brachial pairs (a+b c+d e+f…) or brachial pairs alternating with free brachials (a+b c d+e f...); series of up to 4 successive muscular articulations. Pinnules relatively robust and rigid; insertion deep, carved on arm side and impacting the following brachial pair; synarthrial articulation on brachial with strong symmorphy; concave cover plates varying from lanceolate to rounded; genital pinnules with one row of additional H-shaped plates. Ratio of primibrachial width to upper radial height 0.73 to 0.85. Tegmen with oral cone higher than anal cone; orals large and erect around mouth; anal cone conspicuous in C–D inter-ray and bearing large bulging plates. Conical dorsal cup with ratio of cup height to upper diameter 1 to1.3; basals fused; radials trapezoidal. Columnal symplexies with 8 crenular units; distal syzygies unknown.
