Ref.:
Park, 1994 (p.320); 1995 (p.41, Descr.F, figs.F)
Espèce Paraeuchaeta paraprudens - Planche 1 de figures morphologiquesissued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 1995, 29. [p.139, Fig.29].
Female: a, forehead (left side); b, urosome (left); c, d, genital somite (left, right, respectively); e, outer lobe of Mx1; f, P1 (anterior); g, P2 (anterior).

Nota: Similar in habitus to P. prudens but in lateral view, rostrum less elongated; anterior margin of forehead anterior to frontal eminence more or less curved inward.
Dorsal margin of genital somite only slightly arched and in some specimens with an inconspicuous hump postrior to middle of somite. Ventral margin of genital flange slightly emarginate, oblique in a posteroventral direction. Posterior edge of genital field extending to a greater extent beyond posterior edge of genital flange. Posterior margin of genital prominence straight and as long as posterior ventral wall of somite.
2nd urosomal somite in lateral view with a low dorsal hump about 1/3 its length from proximal end.
Cephalosomal appendages similar to those of P. prudens except for Mx1, in which 1st endopodal segment with 7 setae and outer lobe with 7 long setae followed proximally by 2 small setae.

1 - See key to species Groups and independent species of Paraeuchaeta (p.30): malayensis species Group.
2 - Outer spine of 2nd exopodal segment (or the 2nd of the first 2 exopodal segments forming a proximal, compound segment) of P1 normally developed (Fig.29-f).
3 - Outer lobe of Mx1 with 7 long setae in addition to 1 or 2 minute setae proximally (Fig.29-e).
4 - Genital somite without a conical process on left side close to anterior base of genital prominence (Fig.29-c).
5 - Dorsally and ventrally, genital somite symmetrical.
6 - Laterally, genital flange with normal posterior lobe (Fig.29-c).
7 - Laterally, genital somite with more or less smooth dorsal margin (Fig.29-c).
8 - Laterally, genital prominence with nearly straight or only slightly bulging posterior margin (Fig.29-c).
9 - Outer lobe of Mx1 with 7 long setae plus 1 or 2 very minute setae (Fig.29-e).
10 - Laterally, genital prominence with posterior margin equal to or longer than posterior ventral wall of somite (Fig.29-c).
11 - Laterally, posterior margin of genital prominence and posterior ventral wall of somite forming an angle of more than 140° (Fig.29-c).
12 - Laterally, genital prominence with posterior margin about as long as posterior ventral wall of somite (Fig.29-c).
13 - In P1 exopod, 2nd outer spine reaching base of 3rd outer spine (Fig.29-f).
14- Laterally, posterior margin of genital prominence straight and more or less distinct from posterior ventral wall of somite (Fig.29-c).
