| 2 | Diameter (mm) | 4.5–4.8 | 3.5–3.7 | 11.5 | 5 | 6 | 4 | 5 | 5 | 4.03–6.91 |
| 3 | Segment number | 61–123 | 82–93 | 123 | ? | 125 | 115 | 118 | 129 | 56–144 |
| 4 | First dorsal pore | 11/12 | 9/10 | 12/13 | 12/13 | 12/13 | 12/13 | 12/13 | 11/12 | 11/12 or 12/13 |

| 6 | Male pore | in copulatory pouch with transverse slit like opening male genital region expanded laterally | in copulatory pouch with C-shaped opening | the male pores are on conical papillae on xviii | at the centre of a smooth circular disc, deeply retracted into a parietal invagination, with a short transverse slit-like aperture | apertures are wide slits in the setal circle of xviii with wrinkled margins. | apertures are transverse slits in the setal circle of xviii with antero posterior lips in contact with each other | conspicuous orifices separated from each other by a fairly wide interval | minute and on a porophore within a copulatory chamber opening to the exterior through a transversely slit-like equatorial aperture | inside copulatory pouches in xviii, and the openings slit or round shaped. |
| 7 | Spermathecae | ampulla obovate or ovate, duct stout, conical, muscular with flat top, long stalked diverticulum terminating in a zig-zag looped swollen receptacle. | ampulla oval, with relatively larger swollen spermathecal duct; diverticulum enlarged with looped end. | ampulla saclike, shortly ovoid in shape, duct moderately stout not shining, diverticulum long and thin, and irregularly twisted. | spermathecae small, duct almost confined to the parietes, diverti culum long looped or zigzag. | ampulla is longer than the duct, diverticulum composed of a thick-walled stalk. | duct is short, diverticulum bent into a series of zigzag loops. | ampulla pear shape, diverticulum zigzag | small, diverticulum tubular | ampulla mushroom-shaped with longitudinal grooves on the surface, L-shaped diverticulum. |
| 8 | Genital marking gland | 2 stalked spherical or mushroom shaped in vii, viii, and xi, buried in parietes. | single stalked, connecting to spermathecal ducts. Sometimes, 2–3 sessile in copulatory pouch | very numerous corresponding to the pitted areas stalked. | absent | absent | absent | absent | one finely acinous, 2–4 with short stalks passing to markings within the chamber | 2–4 stalked, attached to each ampulla duct. 3–4 in wall of each copulatory pouch in segment xviii. |
| 9 | Lateral intestinal caeca | In xxvii, and extends upto xxii | xxvii–xxv | xxvii–? | xxvii–? | xxvii–xxiv | xxvii into xxv | xxvii–xxiv | xxvii–xxv | xxvii–xxiv |
| 10 | Intestinal origin | xiv | xv | xv | xvi | xv | xvi | xvi | xv | xv |
