Microcotyle pempheri

The haptor is in form of an inverse triangle and bears 75-103 clamps, arranged as two rows, one on each side.

The digestive organs include an anterior, terminal mouth, a globular to oval pharynx, a simple oesophagus bifurcating posteriorly to the genital pore and a posterior intestine with two branches provided with short lateral branches.

The reproductive organs include an anterior large cup-shaped muscular genital atrium, densely armed with thornlike spines, a dorsal vagina opening some distance posteriorly to the genital pore, a single tubular ovary shaped like a question mark, vitellaria and 11-21 testes oval or irregular in shape.

[1] The species can be distinguished from the most closely related species Microcotyle emmelichthyops Yamaguti, 1968[2] by the absence of a posterior chamber in the genital atrium, a smaller number of testes and the structure of the middle spring of the clamp.

[1] The type and only recorded host of the species is the sweeper, Pempheris xanthoptera (Pempheridae).
