Planche 1 issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 1995, 29. [p.170, Fig.60]. a, Female: a, forehead (left side); b, urosome (left); c, genital somite (left); d, Mx1 (first inner lobe omitted), posterior; e, basis and endopod of Mx1 showing variation in setation; f, P1 (anterior); g, P2 (anterior).
Nota: Similar in habitus including rostrum to P. abbreviata but different. Urosome including genital somite more slender. P2 exopod with 2nd outer spine of 3rd segment longer than 1st by about 1/3 its length and about 2/3 length of outer spine of 2nd segment. Dorsal wall of genital somite more convex 1/4 its length from proximal end. Posterior lobe of genital flange conspicuously produced in form of small conical process pointing posteroventrad. Posterior edge of genital field produced into a lows and wide ridge some distance from genital flange. Posterior margin of genital prominence togeyjer with posterior ventral wall of somite forming a strongly curved arch. Cephalosomal appendages similar to those of P. abbreviata except that basis of Mx1 with 5 setae as in P. malayensis and 1st endopodal segment in some specimens with 4 setae instead of 5, with small innermost seta missing. Swimming legs also similar to P. abbreviata with exception: In P2 exopod, 2nd outer spine of 3rd segment longer than 1st about 1/3 its length and about 2/3 length of outer spine of 2nd segment.
Planche 2Paraeuchaeta parabbreviata Female: 1 - See key to species Groups and independent species of Paraeuchaeta (p.30): malayensis species Group. 2 - Outer spine of 2nd exopodal segment of P1 short of reaching middle of following segment (Fig.60-f). 3 - Laterally, dorsal margin of genital somite broadly arched (Fig.60-c). 4 - Laterally, genital flange appearing bilobed (Fig.60-c). 5 - Laterally, genital somite about 1.6 times as long as deep (Fig.60-c).

Les appendices du cephalosome sont similaires à ceux de P. abbreviata, excepté le basis de Mx1 avec 5 soies et le premier segment de l'endopodite chez quelques spécimens avec 4 soies au lieu de 5, et la petite soie la plus interne absente. Les pattes natatoires montrent aussi quelques menues différences (voir l'exopodite de P2).
