issued from : T. Mori in The pelagic Copepoda from the neighbouring waters of Japan, 1937 (2nd edit., 1964). [Pl.51, Figs.11-14]. Female: 11, P5; 12, A2; 13, habitus (dorsal); 14, Md.
issued from : Fazal-Ur-Rehman in Crustaceana, 1973, 25 (2). [p.115, Figs.13-27]. Female (from off Karachi): 13, habitus (dorsal); 14, A1; 15, A2; 16-17, Md (mandibular blade); 18, Mx1; 19, Mx2; 20, Mxp; 21-24, P1 to P4; 25, P5; 26-27, Md (another specimen from Patany Bay, Siam).
Nota: Caudal rami with distinct asymety, left ramus slightly narrower and smaller than the right. The specimens agree with the morphological characters described by Giesbrecht (1892), but differ in the following aspects. Denticles on the inner side of the left P5 are absent, as in Scott (1909) for a specimen collected by the Siboga Expedition; the marginal spines on the outer side of the right P5 are present in some cases, absent in others; specimens collected from Patany Bay, Siam, in 1909, revealed marked resemblances in the structure of P5, however, Md of the Siam's specimen differed in having 6 cutting teeth, as compared to 5 in the Karachi's specimen, which corresponds to the original figure and description by Giesbrecht (1892, Pl. 31, fig.5).
issued from : Fazal-Ur-Rehman in Crustaceana, 1973, 25 (2). [p.114, Figs.1-12]. Male: 1, habitus (dorsal); 2, right A1; 3, A2; 4, Md (mandibular blade); 5, Mx1; 6, Mx2; 7, Mxp; 8-11, P1 to P4; 12, P5.
Nota: A1 18-segmented, the right one being geniculated with the flexing located between the 14th and 15th segments; antennal segments between 13 and 15 finely serrated, the 8th and 11th segments carry small spines. 4th and 5th thoracic segments separated. Right P5 2-segmented, basal segment broad and triangular, it is provided with 2 finger-like projections set with nodulated protuberances (Pl. 1: top) and with a single seta; the terminal segment is strongly curved and arches over the first, carrying 4 small inner setae; the left P5 3-segmented, excluding the 1st (basal) segment; the proximal segment is the broadest but the two subsequent segments are smaller, each of these segments carries 1 seta on the outer margin; the terminal segment carries in addition 2 small spines (1 located terminally and 1 slightly posterior to it), 2 inner setae, and several distinct spinules near the tip arranged in 7 or 8 semicircular rows (Pl. 1: below)
issued from : Fazal-Ur-Rehman in Crustaceana, 1973, 25 (2). [p.118, Pl.1]. SEM of P5: (top) right P5, showing the finger-like process bearing nodulated protuberances; (below) left P5, showing the arrangement of the spinules in distinct rows.
