Acartiella natalensis (Connell & Grindley, 1974) (F,M) | |
| | | | | | | Syn.: | Acartia (Acartiella) natalensis Connell & Grindley, 1974 (p.89, figs.F,M); Wooldridge & Erasmus, 1980 (p.107, tidal utilization); Jerling, 2008 (p.55, Tabl.1); Jerling & al., 2010 (p.543, Table 1, fig.3);
Acartia natalensisKibirige & Perissinotto, 2003 (p.727, Table 1, 2, fig.5, seasonal distribution) |  issued from : A.D. Connell & J.R. Grindley in Ann. S. Afr. Mus., 1974, 65 (3). [p.90, Figs.1-12]. As Acartia (Acartiella) natalensis. Female (from Mtentu River estuary): 1, habitus (dorsal); 3, urosome (dorsal); 6, A2; ; 7 Md (cutting edge); 8, Mxp; ; 9, P1; 11, P5. Nota: A1 22 apparent segments, but 'segment' 2 apparently compounded of 3 segments and 'segment' 4 of 2, giving 25 true segments; segments 13 to 20 (apparently 10 to 17) have a row of small spines Male: 2, habitus (dorsal); 4, urosome (dorsal); 5, geniculate portion of right A1; 10, P4; 12, P5 (posterior); 12 a, c, right P5 (anterior view); 12 b, left P5 (anterior view). Nota: The last urosome segment has a couple of small spines, and there are usually 2 or 3 on the outer edge of the caudal rami; only the left ramus has a short curved accessory seta, whilethe plumose setae are similar tothose of the female.A1 extend to the distal end of the caudal rami; the left A1 is as in the female, while the right has only 17 apparent 'segments', several of them compound; the geniculation is between 'segments 15 and 16 these being compounds of true segments 17-18 and 19-21 respectively; apparent segment 9 bears a short heavy spine, while 10 and 11 are swollen; 'segments' 14, 15 and 16 bear serrated, sabre-like spines. Right P5 does however form a well-developed clasping apparatus (as specified by Sewell, 1914, in his definition of the subgenus); the detail of the terminal structures of left P5 segment 2-3 was difficult to determine clearly (see microphotographs by scanning electon microscope in fig.24-25). Scale bars in microns.
