 issued from : S. Ohtsuka & J.W. Reid in J. Crustacean Biol., 1998, 18 (4). [p.796, Fig.11, C-D]. Male: C, P5 of 5th copepodid stage; D, P5 of adult. Scale bar in mm. Nota: Note newly formed P5 of adult stage within preceding stage (thick dotted line in C). Arrows in C and D indicate a presumed homologous seta. The structure of the adult male P5 of Tortanus, in particular the right leg, has not been clearly understood. Giesbrecht (1892) thought that the right leg was composed of a coxa, basis, and 2-segmented exopod (the exopod forming a chela). Through observations of the 5th copepodid stages of males of several species, we have concluded that this system is incorrect. The most important tool to trace the homology of segments and elements through development is to examine the newly formed appendage under the cuticle of the preceding stage (see in Hulsemann, 1991, p.105). The 2nd segments of the adult male P5, with an outer (or posterior) seta on each side, are referred to as the basis. Both coxae and the intercoxal sclerite are completely fused to form a common base in the 5th and adult stages. The segment (s) distal to the basis were called the exopod (Giesbrecht,1892; and others) or endopod (Bowman, 1971). Presumably the process on the right basis of the 5th copepodid stages of T. discaudatus and T. derjugini corresponds to the vestigial endopod.

 Issued from : R.B.S. Sewell in Spolia Zeylanica, 1914, 9. [Pl.XXI, Fig.5]. Male (from Gulf of Mannar): P5. Nota: Right A1 16-segmented (segments 1-5, 19-21, and 22-25 fused). Proportional lengths of urosomites and furca as 14:14:11:8:15:72. Sewell points to the characteristics female following: A1 17-segmented (segments 1-7, and 13-14, apparently fused. P5 asymmetrical, but the degree of asymmetry is very slight (not comparable to that in T. forcipatus.
