Acartia (Acanthacartia) tropica Ueda & Hiromi, 1987 (F,M) | |
| | | | | | | Syn.: | Acartia plumosa : Sewell, 1932 (p.395); 1934 (p.80); Wellershaus, 1969 (part., p.271, figs.70, 75, no 66, 67.); Abraham, 1970 (p.115, figs.1, 3); Tranter & Abraham, 1971 (p.224, figs.2 Af, 2 Bf). | | | | Ref.: | | | Ueda & Hiromi, 1987 (p.233, figs.F,M). |  issued from : H. Ueda & J. Hiromi in Crustaceana, 1987, 53 (3). [p.227, Fig.2, g-h]. Female (from Chao Praya River mouth, Thailand): g, h, posterior metasome and urosome (dorsal and lateral, respectively). Nota: Armature on posterior corner of metasome similar to that of A. sinjiansis, but spines at ventralmost locus nearly as large as those at dorsalmost locus; each locus with 0-3 (usually 1 or 2) spines. Genital segment with 9-18 spines on posterodorsal margin; these spines not grouped at loci but evenly distributed; ventral surface with sevral rows of very minute hair-like spinules. 2nd urosomal segment with 6-10 posterodorsal spines; medial 2 spines larger than lateral ones and larger than spines on genital segment. Urosomal segment 3 with ventrolateral hairs. Caudal rami Length/width 1.9-2.2. A1 with 1 rowof spinules on each ventral surface of 9th to 12th segments.

 issued from: H. Ueda & J. Hiromi in Crustaceana, 1987, 53 (3). [p.228, Fig.3, c, e, h]. Female: c, forehead (ventral); e, right A1 (8th-13th segments, ventral view); h, P5 (ventral view).

 issued from : H. Ueda & J. Hiromi in Crustaceana, 1987, 53 (3). [p.229, Fig.4, f-g]. Male: f, g, urosome (dorsal and lateral, respectively). Nota: Urosomal segment 2 with 11-12 spines on posterodorsal and posterolateral margins; lateral spines not smaller than dorsal ones; ventral surface with spines at 2 loci on each side, each locus with 1-3 spines. 3rd and 4th urosomal segments with 4-8 and 4-6 posterodorsal spines, respectively (sometimes 4 loci can be distinguished on both segments); these spines usually larger than those on 2rd urosomal segment. Anal segment with ventrolateral hairs. Caudal rami Length/width 1.1-1.3.

Female (from Cochin Backwater, area between outlet and Aroor Bridge): 70, last thoracic segment and urosome (dorsal). Nota: - Anal operculum without spines. - Caudal rami length : breadth = 10 : 6. - Eye of both sexes generally rd, pink or blue, sometimes colourless.
