 issued from : J.G. Greenwood in Proc. R. Soc. Qd, 1978, 89. [p.16, Fig.7, a, b, d, f, i, j]. As Acartia pacifica forma typica. Female (from Moreton Bay, E Australia): a, A1 (segments15-19); b, posterior metasome and urosome (dorso-lateral); i, j, P5. Male: d, posterior metasome and urosome (dorso-lateral); f, P5. Remarks: males A. pacifica and A. mertoni with ventrolateral setae on 2nd urosomal segment; 3rd urosomal segment ofmale mertoni with 2 larger spines dorsolaterally on posterior margin, row of 6-8 spinules between. Male P5 slightly different proportions in the two species: in A. pacifica inner projection of right exopodal segment 2 is larger (length from outer border similar to that of segment) with ridge on posterior surface giving slightly bifid appearance; length of left exopodal segment 1 similar to exopodal segment 2 and less than basal segment, inner spine on exopodal segment 2 less than twice length of segment, in A. mertoni length of inner projection on right exopodal segment 2 less than that of segment, inner end rounded, distal end flattened; left exopodal segment 1 longer than exopodal segment 2 or basal segment, inner spine on exopodal segment 2 more than twice length of segment. Females in both species with base of terminal spine gibbose and margins of spine finely denticulate, but seta and spine of similar length in A. mertoni, seta twice length of spine in A. pacifica.

Nota Female: Posterolateral ebds of last thoracic segment produced into strong and long spiniform processes, reaching to middle of urosomal segment 1, with a pair of small spines pn dorsal surface (Steuer’s specimen has a pair of single spine instead 2). Dorsal surface of urosomal segments 1 and 2 each with 2 spinules on their dorsal margins distally ; spinules on urosomal segment 2 larger than those of urosomal segment 1.
