- Heterobothrium lamothei n. sp. (Monogenea: Diclidophoridae) from the gills of Sphoeroides testudineus (Pisces: Tetraodontidae) from the coast of Yucatán, Mexico Víctor M. Vidal-Martínez Edgar F. Mendoza-Franco Biología Monogenea Sphoeroides Heterobothrium Gulf of Mexico Yucatán Peninsula The presence of a member of the genus Heterobothrium is described for the first time from the coast of Yucatán Peninsula, southeastern Mexico. Heterobothrium lamothei n. sp. is recorded parasitizing the gills of the tetraodontid fish Sphoeroides testudineus (Linnaeus, 1758) from 4 coastal lagoons in Yucatán: Celestún (20° 52' N, 90° 24' W), Chelem (21°15'N89°45'W), Dzilam (21°35'N 88°35'W) and Río Lagartos (21°22'N 87°30'W). The new species differs from the other species described in the genus, by a combination of characters including a copulatory organ armed with 12-15 genital hooks, the distal pair of clamps smaller in comparison with the 3 other pairs and by having 15-26 testes. The infection parameters were for Celestun, 47 % of prevalence, number of fish examined (n) = 47, mean abundance of 1.76 ± 9.62; Chelem, 20 % (n = 30), 0.53 ± 8.48; Dzilam, 2 % (n = 60), 0.02 ± 0.00; Río Lagartos, 25 % (n = 59), 0.34 ± 1.58. Heterobothrium lamothei n. sp. may be considered as potentially dangerous species for the aquaculture of S. testudineus due to its direct life cycle hat high fish densities would increase the transmission of this monogenean. 2008 artículo científico 1870-3453 https://www.redalyc.org/articulo.oa?id=42519190012 en http://www.redalyc.org/revista.oa?id=425 Revista Mexicana de Biodiversidad application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Biodiversidad (México) Vol.79
