Material examined.

ECH 00161 (paratype) (Fig. 9 A – D View Figure 9 ). (Suppl. material 1) .

Remarks.

Freyella loricata was described based on multiple individuals collected from east of the Kuril-Kamchatka Trench ( Korovchinsky and Galkin 1984). Same as F. giardi , this species was traditionally classified as Freyella but has many shared characters with Freyastera , especially with F. tuberculata . It has inferomarginal plates and lateral spines that begin at the 7 th adambulacral plate, appear at alternate adambulacral plates, and then at every adambulacral plate ( Korovchinsky and Galkin 1984); thus, we reassign this species as Freyastera loricata comb. nov.
