Theletrum lamothei sp. nov. (Digenea), parasite of Echidna nocturna from Cuajiniquil, Guanacaste, and other digenes of marine fishes from Costa Rica
A new species of Theletrum is described from the intestine of two palenose morays, Echidna nocturna, collected in Cuajiniquil, Guanacaste Province, Costa Rica. The new species differs from the type species, T. fustiforme Linton, 1910 by having a subspherical pars prostatica, a subspherical seminal v...

| description | A new species of Theletrum is described from the intestine of two palenose morays, Echidna nocturna, collected in Cuajiniquil, Guanacaste Province, Costa Rica. The new species differs from the type species, T. fustiforme Linton, 1910 by having a subspherical pars prostatica, a subspherical seminal vesicle extending anteriorly to the anterior border of the acetabulum, by the presence of a poorly developed hermaphroditic sac, and by having a larger body size. We also report eight additional species of digeneans parasitizing marine fishes in several localities along the Atlantic and Pacific coast of Costa Rica: Bianium simonei, Didymozoinae (metacercariae), Ectenurus virgulus, Hypocreadium myohelicatum, Lecithochirium microstomum, Pseudolecithaster sp., Stephanostomum casum, and Tergestia laticollis. In addition, we present an updated list of helminth parasites of marine fish from Costa Rica and discuss the importance of including parasites as an integral part of biodiversity inventories.<br>Se describe una especie nueva de digéneo del género Theletrum, parásito del intestino de una "morena pecosa", Echidna nocturna, recolectada en Playa Cuajiniquil, Provincia de Guanacaste, Costa Rica. La nueva especie es diferente de T. fustiforme Linton, 1910, la especie tipo, por presentar una pars prostatica subesférica, una vesícula seminal subesférica que se extiende hasta el borde anterior del acetábulo, por la presencia de un saco hermafrodita y por una mayor longitud del cuerpo. También se registran ocho especies adicionales de digéneos parásitos de peces marinos en varias localidades de las costas del Atlántico y del Pacífico de Costa Rica. Por último, presentamos una lista actualizada de los helmintos parásitos de peces marinos y dulceacuícolas de Costa Rica y discutimos la importancia de incluir a los parásitos como una parte integral de las investigaciones sobre biodiversidad. |
