[2] Microcotyle stenotomi was subsequently redescribed by Linton in 1940 [3] who added only few measurements without improving the original drawings of Goto.

The haptor is symmetrical, occupies about one-third of body length and bears 46 pairs of minute clamps, arranged as two rows, one on each side.

The reproductive organs include an anterior spacious genital atrium opening at level of oesophagus, armed with numerous very small and slightly recurved spines, a medio-dorsal vagina opening midway between the anterior end of the body and the level of the ovary, a single incompletely S-shaped ovary consisting of a convoluted tube, a uterus opening through the genital pore, vitellarium giving off ducts which unite in a Y-shaped reservoir in the midline behind the ovary, an oviduct at the tip of the Y-shaped vitelline reservoir and a number of testes which are posterior to the ovary and present in a great group in the midpart of the body.

[5] In 1913, Maccallum described the process of fertilization and egg-laying of this species:[4] "After a certain amount of friction together, one adult attached by its anterior end (where the genital atrium is located) to the corresponding portion of the other (in the position of the vaginal opening is situated).

As the cirrus and surrounding genital opening are provided with circles of spines, the animals can preserve their position during fertilization.

Once properly shaped, the egg passes along to the muscular portion of the uterine canal that the openings of the shell gland.
