Species Ratania flava - Plate 8 of morphological figures

Plate 8 issued from : M. Saraswathy in Bull. centr. Res. Inst. Univ. Kerala, 1961, (C)8. [p.144, Fig.1].
Female (from Trivandrum coast, SW India): 1, habitus (dorsal); 2, A1; 3, A2; 4, Md; 5, Mx1; 6, Mx2; 7, Mxp; 8, Mx1, Mx2 and Mxp in situ; 9, ventral view of anterior end; 10-13, P1 to P4; 14, urosomal segment 1 with P5.

Male: 15, habitus (dorsal); 16, A1; 17, urosomal segment 1 with P5.
Nota: Giesbrecht has illustrated an elongated Md with a distinct strongly dentate gnathobase. In the present specimen Md is quite different from that of Giesbrecht, but is in complete agreement with the Md of other siphonostomes.. According to Giesbrecht, the 3rd segment of the endopod of P3 and P4 possesses only 2 setae, but in the present specimens the corresponding segment of P3 has 3 setae and for P4 only 2.

Remarks

Meso-bathypelagic. Sargasso Sea: 0-500 m (Deevey & Brooks, 1977,, Station "S");
For Saraswathy (1961, p.146) the specimens show that the segmentation of A1 5-segmented, is not clear because some of the segments with indistinct subdivisions.
Boxshall (1979, p.240) points to: Saraswathy (1961) reported that many of the segments of the 5-segmented A1 in female showed subdivisions. No significant subdivisions were observed in the Boxshall's material.
Saraswathy (1982, p.638) notes that this species was present only 15 stations out of the 340 samples examined; Salinity at the positive stations ranged from 36.01 to 32.78 p.1000.
