Paraeuchaeta anfracta Park, 1995 (F) | |
| | | | | | | Ref.: | | | Park, 1994 (p.320); 1995 (p.65, Rem.F, figs.F) |  issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 1995, 29. [p.172, Fig.62]. Female: a, forehead (left side); b, urosome (left); c, d, genital somite (left, right, respectively); e, Mx1 (first inner lobe separated), posterior; f, P1 (anterior); g, P2 (anterior). Nota: Rostrum relatively small, pointing straight downward; its anterior margin beginning some distance from suprafrontal sensilla and straight. Supralabrum with distal end pointing downward. Genital prominence high; its anterior margin slightly bulging and sloping about 55° with respect to ventral wall of somite; its posterior margin perpendicular to ventral wall of somite. Genital flange with well-defined posterior lobe in form of conical process pointing posteroventrad. Posterior edge of genital field produced into a small process pointing in same direction as posterior lobe of genital flange but not projecting beyond posterior margin of prominence. Posterior region of ventral wall of genital somite including posterior part of prominence densely pitted. Cephalosomal appendages similar to those of P. malayensis except that basis of Mx1 with 4 setae, without small outermost seta; 1st endopodal segment with 4 setae, and outer lobe with 7 long setae and 1 small seta proximally.
