Acartiella keralensis (Wellershaus, 1969) (F,M) | |
| | | | | | | Syn.: | Acartia (Acartiella) keralensis Wellershaus, 1969 (p.265, figs.F,M); Goswami & Goswami, 1974 (p.109, fig. caryotypes); Barthélémy, 1999 (p.860, figs.F) |  Issued from : S. Wellershaus in Veröff. Inst. Meeresforsch. Bremerh., 1969, 11 (2). [p.264, Fig.37-43]. Female (from Cochin Backwater, India): 37, urosome (ventral; anal operculum on dorsal side)39, A1 (A,A indicate the same place); 40, habitus (dorsal; black marks indicate blue-violet pigmentation); 41, P5. Nota: Ratio prosome : urosome = 1.37. Forehead without rostrum or filaments. Basipod 2 (= basis) of A2 with 2 setae; the distance between these setae and endopod is longer than in Acartiella tortaniformis; exopod fused with the basipod 2. Proportions of the urosomal segments 24, 16; anal-right Caudal rami 61 %. Male: 38, A1 (segments 14 to 25); 42, urosome (dorsal); 43, A2.
Scale : single line = 0.1 mm ; double line = 0.05 mm.

 Issued from : S. Wellershaus in Veröff. Inst. Meeresforsch. Bremerh., 1969, 11 (2). [p.266, Fig.44]. Male: 44, P5.
Scale : single line = 0.1 mm ; double line = 0.05 mm. Nota: Triangular projection on the coxa has half the length of the right basis. Exopodal segment 2-3 shows a characteristic shape, and the left basis has a rounded projection on the inner margin.

 issued from : R.-M. Bathélémy in J. Mar. Biol. Ass. U.K., 1999, 79. [p.858, Fig.1, A-B]. Scanning electon miccrograph. Female: A, genital double-somite (ventral ); B, detail of external genital area with insemination. Note the spermatophoral products (asterisk) covering the gonoporal plates under the opercular pad (large arrow) Scale bars: 0.030 mm (A), 0.020 mm (B). Symbols: arrowhead = cuticular folds limiting the genital area; large arrow = opercular pad; gp = gonoporal plate.

 Issued from : S. Wellershaus in Veröff. Inst. Meeresforsch. Bremerh., 1969, 11 (2). [p.265]. As Acartia (Acartiella) keralensis. Female: Proportions of the segments of A1.

 Issued from : S. Wellershaus in Veröff. Inst. Meeresforsch. Bremerh., 1969, 11 (2). [p.265]. As Acartia (Acartiella) keralensis. Female: Proportions of the abdominal segments for 5 animals.
|
 Issued from : S. Wellershaus in Veröff. Inst. Meeresforsch. Bremerh., 1969, 11 (2). [p.267]. As Acartia (Acartiella) keralensis. Male: Proportions of abdominal segment for 5 animals.
|
 Issued from : S. Wellershaus in Veröff. Inst. Meeresforsch. Bremerh., 1969, 11 (2). [p.265]. As Acartia (Acartiella) keralensis. Proportions of the female abdominal segments as an help for distinctions because A. keralensis closely resembles A. minor, A. tortaniformis and A. sewelli. Furthermore, A. keralensis is characterized by the shape of P5.
