status

 

Subfamily Asteroschematinae  Verrill, 1899

Diagnosis. Arms simple, coiled. Disc five lobed, naked or covered with granule- plate- and/or cone-shaped external ossicles, or skin. Teeth triangular and wide, flat, situated on top of the dental plate. Radial shields narrow, multi-layered. Ventral arm plates small, disappearing on middle to distal portion of arms. Arm spines up to three. Genital slits close to periphery of disc.

Remarks. Okanishi & Fujita (2011) reduced the family Asteroschematidae Verrill 1899  , to a subfamily of family Euryalidae  . Soon thereafter, Okanishi & Fujita (2013) restored the family-level status of Asteroschematidae  under the superfamily Euryaloidea. However, the molecular phylogeny of O’Hara et al. (2017) confirmed that the asteroschematds were subfamilial rank. Therefore, in this study, we use subfamilies Asteroschematinae  , Astrocharinae  and Euryalinae  under the family Euryalidae  .
