Paraeuchaeta triloba Park, 1995 (F) | |
| | | | | | | Ref.: | | | Park, 1994 (p.320); 1995 (p.43, Descr.F, figs.F) |  issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 1995, 29. [p.141, Fig.31]. Female: a, forehead (left side); b, urosome (left); c, genital somite (left); d, idem (left, tilted counterclockwise); e, idem (ventral); f, outer lobe of Mx1; g, P1 (anterior); h, P2 (anterior). Nota: Similar in habitus including urosome to P. scotti. Dorsal wall of genital somite nearly straight; genital flange appears trilobed; posterior edge of genital field produced into a relatively small knob; posterior margin of genital prominence distinctly shorter than posterior ventral wall of somite and they meet in a rather smooth curve. Genital somite in both dorsal and ventral view widest at middle with marked genital swelling. Viewed laterally, left side of genital somite with a low ridge close to anterior base of genital prominence, which can be seen more clearly when the somite is tilted. 2nd urosomal somite with a low dorsal hump close to proximal end. Cephalosomal appendages and swimming legs similar to those of P. scotti except that outer lobe of Mx1 with 7 long distal plus 2 small proximal setae.
