Paraeuchaeta sp. A  Bradford, Haakonssen & Jillett, 1983   (F)
Bradford & al., 1983 (p.57, Descr.F, figs.F)
Species Paraeuchaeta sp. A - Plate 1 of morphological figuresissued from : J.M. Bradford, L. Haakonssen & J.B. Jillett in Mem. N.Z. Oceanogr. Inst., 1983, 90. [p.58, Fig.31].
Female: A, genital segment (dorsal); B, genital prominence (right lateral view); C, genital segment (left lateral view); D, genital field (ventral); E, exopod of P1; F, exopod segment 3 of P2.

- Posterolateral corners of metasome not produced, and broadly rounded in dorsal and lateral view.
- Genital segment symmetrical in dorsal view, widest part anterior to middle; ventral wall anterior to genital prominence very depressed in lateral view; genital prominence high and almost perpendicular to segment; genital flanges large and extend over entire length of genital field; lobe-like process extends from posteromedial border of flange in ventral view; left process of genital flange larger than right, in lateralview seen as ventrally directed lobe from posterior part of genital flange.
- Appendicular caudal setae geniculate.
- None of the 6 distal setae of Mx2 covered with long spines in addition to short spinules.
- None of the long setae on endopod of Mxp terminate in spinule.
- P1 exopod: Aa minute; Bb = 6/7 BC; Cc > BC.
- P2 exopod: Aa = AB; Bb = 1/2 BC; Cc = 7/9 CD; Dd = 1/3 CD.

Rem.: These specimens damaged resembles P. calva and P. polita, but the latter two have symmetrical genital fields.
