Species Paraeuchaeta orientalis - Plate 2 of morphological figuresissued from : M.V. Heptner in Trudy. Inst. Okeanol., 1971, 92. [p.100, Fig.13]. As Pareuchaeta orientalis.
Female (from Kuril-Kamchatka Trench).
Nota: Formula of the exopod of P1 spines on the last two segments, successively: Bb ≈ 1/5-1/6 BC; Cc > BC (Cc ≈ 1-1 1/3 BC). P2: Aa > AB (Aa = AB + 1/2 Bb); Bb = BC; Cc < CD (Cc = 3/4 CD). Variant: Aa = AB+ 3/4 Bb; Bb> BC; Bb < BC (Bb ≈ 3/4 BC); Cc = 9/10 CD. [cf. legend in drawings of Heptner, 1971, for Pareuchaeta rubra]
