During a survey of the parasites of freshwater fishes from cenotes (sinkholes) of the Yucatan Peninsula the following species of monogeneans were found on cichlid, pimelodid, characid and poeciliid fishes: Sciadicleithrum mexicanum Kritsky, Vidal-Martinez et Rodriguez-Canul, 1994 from Cichlasoma urophthalmus (Günther) (type host), Cichlasoma friedrichsthali (Heckel), Cichlasoma octofasciatum (Regan), and Cichlasoma synspilum Hubbs, all new host records; Sciadicleithrum meekii Mendoza-Franco, Scholz et Vidal-Martínez, 1997 from Cichlasoma meeki (Brind); Urocleidoides chavarriai (Price, 1938) and Urocleidoides travassosi (Price, 1938) from Rhamdia guatemalensis (Günther); Urocleidoides costaricensis (Price et Bussing, 1967), Urocleidoides heteroancistrium (Price et Bussing, 1968), Urocleidoides anops Kritsky et Thatcher, 1974, Anacanthocotyle anacanthocotyle Kritsky et Fritts, 1970, and Gyrodactylus neotropicalis Kritsky et Fritts, 1970 from Astyanax fasciatus; and Gyrodactylus sp. from Gambusia yucatana Regan. Urocleidoides chavarriai, U. travassosi, U. costaricensis, U. heteroancistrium, U. anops, Anacanthocotyle anacanthocotyle and Gyrodactylus neotropicalis are reported from North America (Mexico) for the first time. These findings support the idea about the dispersion of freshwater fishes and their monogenean parasites from South America through Central America to southeastern Mexico, following the emergence of the Panamanian isthmus between 2 and 5 million years ago.
在对尤卡坦半岛天然井（灰岩坑）淡水鱼寄生虫的一项调查中，在丽鱼科、油鲶科、脂鲤科和花鳉科鱼类上发现了以下单殖吸虫物种：1994年发现的墨西哥Sciadicleithrum mexicanum Kritsky、Vidal-Martinez和Rodriguez-Canul，寄生于眼斑丽鱼（Günther）（模式宿主）、弗里氏丽鱼（Heckel）、八带丽鱼（Regan）和联斑丽鱼（Hubbs），均为新宿主记录；1997年发现的米氏Sciadicleithrum meekii Mendoza-Franco、Scholz和Vidal-Martínez，寄生于米氏丽鱼（Brind）；危地马拉异双鳍鲶（Günther）上的查氏原异双盘吸虫（Price，1938）和特拉瓦索斯原异双盘吸虫（Price，1938）；阿氏新双线盘吸虫（Price和Bussing，1967）、异钩新双线盘吸虫（Price和Bussing，1968）、盲新双线盘吸虫（Kritsky和Thatcher，1974）、无棘单杯吸虫（Kritsky和Fritts，1970）以及新热带三代虫（Kritsky和Fritts，1970）寄生于条纹魮脂鲤；还有来自尤卡坦花鳉（Regan）的三代虫属未定种。查氏原异双盘吸虫、特拉瓦索斯原异双盘吸虫、阿氏新双线盘吸虫、异钩新双线盘吸虫、盲新双线盘吸虫、无棘单杯吸虫和新热带三代虫首次在北美洲（墨西哥）被报道。这些发现支持了这样一种观点，即200万至500万年前巴拿马地峡出现后，淡水鱼及其单殖吸虫寄生虫从南美洲经中美洲扩散到墨西哥东南部。
