Bathyferdina caelator Arai & Fujita 2021

Diagnosis

Body stellate, R/r=2.0–2.3, with disk broad, arms triangular, interradial arcs rounded. Abactinal, actinal and adambulacral plates with glassy bosses. Abactinal plates, uniform in size and shape. Superomarginal plates rectangular to barrel–like in outline, and regularly decreasing in size from the interradius to arm tips. Glassy boss/ ridge present on abactinal and actinal plates. One or two glassy bosses on the center of each adambulacral plate. Furrow spines three.

Comments

This species is distinguished from B. aireyae Mah 2017 in having the presence of glassy bosses on the abactinal, actinal and adambulacral plates, while lacking them on the marginal plates ( Arai & Fujita 2021). Arai and Fujita (2021) also discovered glassy, embossed granules on the actinal and adambulacral plates and pedicellariae in Bathyferdina aireyae Mah 2017 .
