[1] Microcotyle algeriensis was described Ayadi et al., in 2017, from the gills of the small red scorpionfish Scorpaena notata (Scorpaenidae) collected at Bouharoune off the Algerian coast.

Thus, Ayadi et al., (2017) suggested that a correct specific identification of Microcotyle spp from scorpaeniform fishes must relay on a detailed morphological and molecular study of specimens from different locations and hosts.

The digestive organs include an anterior, terminal mouth, a globular pharynx, a long thin oesophagus without lateral diverticula and a posterior intestine that bifurcates at level of genital atrium in two lateral branches not united posteriorly, one branche ends at level of the testes while the other extends into the haptor.

The reproductive organs include an anterior genital atrium, armed with numerous conical spines, arranged as one main anterior group and two postero-lateral smaller groups called (“pockets” of Mamaev), a medio-dorsal vagina located posterior to genital atrium, a single tubular ovary consisting of a convoluted tube and 9–20 intercaecal post-ovarian testes in posterior half of body proper.

[1] The type-host is the small red scorpionfish Scorpaena notata, the identification of the host was confirmed by molecular barcoding of the COI gene.
