Checked: verified by a taxonomic editorDiagnosis Tropiometroidea with centrodorsal discoidal to low hemispherical with broad, flattened, cirrus-free aboral apex. No radial pits or subradial cleft. Aboral star present only in fossil Kiimetra miocenica. Large cirrus sockets without distinct sculpturing, crowded in 1-2 (rarely 3) irregular rows, commonly corresponding to 15-20 short, irregular columns. Cirrals short; distal cirrals with aboral ridge or spine. Tip of rod-shaped basals exposed interradially or concealed. Radials exposed or concealed, commonly with lateral margins visible and separating adjacent primibrachials. Radial articular facet crescent shaped, steep and wide, with muscle fossae reduced to thin, curved bands. Radial cavity very wide. Arms 10-40. Brachitaxes of 2 ossicles (except 4 in Reometra). Synarthry between brachials 1-2; syzygy between brachials 3-4 and more distally at intervals of 2-7. First pinnule delicate and weak but with first 2 segments enormously enlarged; following pinnules elongate, enlarged, stiffened, and composed of elongate pinnulars. Pinnules with distinct ambulacral covering plates. Disk globose, covered with a pavement of plates, and easily detached. [details]
