Paraeuchaeta regalis (Grice & Hulsemann, 1968) (F,M) | |
| | | | | | | Syn.: | Euchaeta regalis Grice & Hulsemann, 1968 (tab.2, p.329, Descr.F, figs.F, non M); Park, 1978 (p.253, figs.F,M); Ward & Wood, 1988 (p.48, tab.1);
No Euchaeta regalis : Grice & Hülsemann, 1968 (p.331, fig.M) | | | | Ref.: | | | Bradford & al., 1983 (p.51, figs.F,M, Rem.); Park, 1994 (p.321); 1995 (p.50, Rem.F,M, figs.F,M); Bradford-Grieve & al., 1999 (p.880, 925, figs.F) |  issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 1995, 29. [p.150, Fig.40]. Female: a, forehead (left side); b, urosome (left); c, d, genital somite (left, right, respectively); e, outer lobe of Mx1. Nota: Sililar in habitus including forehead and urosome to P. calva and can be distinguished from it only by carefully comparing the features of genital somite in lateral view. Anterior and posterior lobes of genital flange separated by deep notch. Posterior lobe produced into a large conical process pointing usually straight downward. Posterior section of genital somite as measured from distal end of genital flange about 1.8-1.9 times length of flange (as opposed to 1.4-1.8 times length of flange as found in P. calva. Cephalosomal appendages including Mx1, outer lobe of which has 5 long and 3 minute setae, and swimming legs practically identical to those of P. calva. Male: f, forehead (left); g, last pedigerous and genital somites (left); h, distal exopodal segments of 5th leg (lateral, tilted clockwise).

 issued from : T. Park in Antarctic Res. Ser. Washington, 1978, 27. [p.254, Fig.99]. As Euchaeta regalis. Female: A, forehead (lateral); B, C, D, distal end of metasome and genital segment (left side, right side, and ventral, respectively); E, F, posterior part of metasome and urosome (dorsal and left side, respectively); G, P1; H, P2. P1-2: legs (anterior). Nota from Bradford & al. (1983, p.52): - P1 exopod female: Aa minute; Bb = 4/5 BC; Cc > CD. - P2 exopod female: Aa = Ab; Bb = 1/3 BC; Cc = 2/3 CD; Dd = 1/4 CD. (see code of lengths outer spines in the Genus' figure, or in Paraeuchaeta sp. A).

 issued from : T. Park in Antarctic Res. Ser. Washington, 1978, 27. [p.255, Fig.100]. As Euchaeta regalis. Male: forehead (lateral); B, last metasomal and genital segments (left side); C, P1; D, P2; E, P5; F, G, H, distal part of exopod of left P5 (medial, and lateral of different specimens, respectively). P1, 2, 5: legs (anterior). Nota from Bradford & al.(1983, p.52): - P1 exopod male: Aa minute; Bb = 1/3 BC; Cc = 2/3 CD. - P2 exopod male: Aa = 1/2 AB; Bb = 1/3 BC; Cc = 1/2 CD; Dd = 1/4 CD. (see code of lengths outer spines in the Genus' figure, or in Paraeuchaeta sp. A).

 issued from : G.D. Grice & K. Hulsemann in Pacif. Sci., 1968, 22 (3). [p.328, Figs.34-40]. As Euchaeta regalis. Female (from SE Pacific): 34-35, habitus (dorsal and lateral, respectively); 36, forehead (lateral); 37, posterior end of thorax and urosome (dorsal); 38, idem (right lateral view); 39, P1; 40, P2.
