Parvocalanus serratipes  (Sewell, 1912)   (F,M)
Syn.: Paracalanus serratipes Sewell, 1912 (p.332, figs.F,M); 1914 a (p.208); 1929 (p.66, figs.F); 1948 (p.323, 429); Rose, 1956 (p.460); Silas, 1972 (p.645)

Species Parvocalanus serratipes - Plate 1 of morphological figuresIssued from : R.B.S. Sewell in Rec. Indian Mus., 1912, 7. [Pl.XV, figs.6-10]. As Paracalanus serratipes.
Male (from Bay of Bengal): 6, habitus (lateral left side); 7, A2; 8, P1.
Nota: Abdomen length co,tained 2.5 times in that of the cephalothorax. Proportional lengths of urosomites and caudal rami as 10:20:16:16:12:10. Rostrum consists of 2 short stout spines. A1 20-segmented (segments 1-2, 3-6, 7-8, fused).Endopodite of A2 terminates in a nipple-like projection. Left P5 considerably the larger, 4-segmented in addition to the enlarged basal portion.; the proportional lengths of these segments are 15:18:16:12; the penultimate segment bears a distal spinous process and the last segment terminates in 2 processes of unequal length; the right P5 3-segmented and terminates in 2 short processes.

Female: 9, P2; 10, P3.
Nota: Proportional lengths of urosomites and caudal rami as 22:12:11:18:10. A1 23-segmented (segments 1-2 and 8-9 fused) reaching the middle of abdomen, segments 2 to 9 bear a transverse row of fine spines on their posterior surfaces close to the distal border, and on segments 10 to 24 there are longitudinal rows of spines (as in P. aculeatus. 1 st basal segment bears a few spines on its anterior surface1 st exopodal segment bears a small transverse row of spines on its distal external margin. P5 is the same as in P. dubia, but in a few specimens a third small segment was intercalated between the usual two.

Female (from N Indian Ocean): a, genital segment (ventral); b, P5.


Species Parvocalanus serratipes - Plate 3 of morphological figuresissued from : K.S. Kesarkar & A.C. Anil in J. mar. Biol. Ass. UK, 2010, 90 (2); [p.405, Table 2].

Female:N, P5.


Species Parvocalanus serratipes - Plate 5 of morphological figuresIssued from : S. Y. Moon, S.-H. Youn & H.Y. Soh in ZooKeys, 2014, 456. [p.42, Table I].
Female : marphological characters.
Compare with other species of Parvocalanus : (arabiensis, crassirostris, dubia, elegans, latus, leei, scotti).
