Outer lobe of Mx1 with 5 long setae and 1 minute seta proximally. In P1 exopod, outer spine of 2nd segment far short of reaching base of following outer spine. In P2 exopod, although varying considerably in length in proportion to body size, outer spine of 2nd segment usually longer than 2nd outer spine of 3rd segment; marginal lobe bearing 2nd outer spine of 3rd segment separated from segment by a moderately deep incision, which is far short of reaching level of preceding incision.

 issued from : O. Tanaka in Publs Seto Mar. Biol. Lab., 1958, VI (3). [p.339, Fig.67]. As Pareuchaeta barbata. Female: a, forehead (lateral left side); b, last thoracic segment and urosome segments (lateral left side); c, genital somite (ventral); d, exopod of P1; e, exopod of P2.

 issued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1968, XVI (4). [p.228, Fig.5]. As Pareuchaeta barbata. Female: A, last thoracic segment and urosome (lateral left side); B, Mx1.

 issued from : J.M. Bradford, L. Haakonssen & J.B. Jillett in Mem. N.Z. Oceanogr. Inst., 1983, 90. [p.29, Fig.11]. Female: A, habitus (lateral left side); B, genital segment (dorsal); C, idem (lateral right side); D, genital field (ventral, half); E, exopod of P1; F, exopod segment 3 of P2. Nota: - P1 exopod: Aa >1/5 AB; Bb = 5/6 BC; Cc = 1.1/3 BC. -P2 exopod: Aa < AB; Bb < 1/2 BC; Cc ≤ CD. (see code of lengths outer spine in the Genus' figure of Paraeuchaeta, or in Paraeuchaeta sp. A). For the authors this species is almost identical with descriptions of P. farrani (see Park, 1978), which is probably a junior synonym of P. barbata. For Park (1978) the only distinguishing character between female P. barbata and P. farrani (the length of P2 exopod segment 3 second outer edge spine) appears to vary to some extent with body size (the spine tends to be longer as the body size decreases). In the present specimen from south-west pacific, although small (8.1 mm), P2 exopod Cc < CD (fig.13: E), and so would be attribuate to P. farrani if P. barbata and P. farrani prove to be distinct species.
