Diagnosis Florometra with 40-77 cirri, of up to 34 cirrals; longest cirrals with L/W ratio up to 3; distal cirrals usually with well-developed aboral spine; opposing spine conical and terminal claw slender and curved. Proximal brachials more or less strongly spinous and everted distally, or less so or hardly at all, particularly in larger specimens. Third syzygy usually at brachials 14+15. P1 with up to 50 segments; distal pinnulars slightly modified as rudimentary comb, producing a scalloped profile. Middle and distal pinnules with pinnulars mostly hardly longer than wide. [details]
Distribution Antarctica from Enderby Land E to Adelie Land, Ross Sea and Graham Land. Depth range: (?100) 130-594 m. [details]
