Three monogeneans parasitic on marine sciaenid fish from Peru including description of Cynoscionicola veranoi n. sp. (Microcotylidae), and redescription of C. americanus Tantaleán, Martínez and Escalante, 1987 and Hargicotyle sciaenae Oliva and Luque, 1989 (Diclidophoridae)

Cynoscionicola veranoi n. sp. (Monogenea: Microcotylidae) is described based on specimens collected from the gills of lorna drum Sciaena deliciosa (Tschudi, 1846) (Sciaenidae) from Peru. The new species can be differentiated from the other congeneric species by the combination of the following characteristics: (1) haptor with two types of clamps, (2) number and shape of the spines in anterolateral pouches of genital atrium (10–11 curved spines and 3–4 short and bifid spines with a knob in each lateral margin), (3) number and shape of the spines in posterolateral pouches of genital atrium (13–18 bifid spines), (4) 4–6 small spherical unarmed pouches in the genital atrium, and (5) 10–15 testes. In addition, a redescription of Cynoscionicola americanusTantaleán, Martínez and Escalante, 1987 and Hargicotyle sciaenaeOliva and Luque, 1989 (Diclidophoridae) based on examination of type material and newly collected specimens from snakehead kingcroaker Menticirrhus ophicephalus (Jenyns, 1840) and S. deliciosa (type hosts), respectively, are provided herein.


We thank Lidia Sánchez (MUSM) for allowing us access to the type specimens under her care. José L. Luque was supported by a Research fellowship from CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico, Brazil).
