Microcotyle mouwoi
The description by Ishii and Sawada in 1938 includes the following:
"Elongated body 2.2-3.2 mm long and 0.378- 0.55mm wide. Two oval anterior suckers lies at the anterior end of the body.The haptor has 28-30 clamps. The mouth, which opens at the anterior end of the body leads into the pharynx. The pharynx lies in contact with two anterior suckers. The short oesophagus divides into two intestinal canals, which run to near the end of the haptor.
Male organs comprises testicular follicles, longitudinally on the median line at the posterior portion of the body. The vas deferens from testes winds on forward along the ovary, into the genital opening, which has four long spines. The female organs includes the elongated ovary with the slender end posterior and the broad anterior part to the right. The oviduct receives the vitelloduct and becomes the slender ootype. The uterus proceeds forward to the genital opening. The vitellaria fill up the lateral body from a little behind the genital opening to the end of the haptor. The vaginal opening lies median, dorsal and behind the genital opening."
