Rubio-Godoy, Miguel, Paladini, Giuseppe & García-Vásquez, Adriana, 2010, Gyrodactylus jarocho sp. nov. and Gyrodactylus xalapensis sp. nov. (Platyhelminthes: Monogenea) from Mexican poeciliids (Teleostei: Cyprinodontiformes), with comments on the known gyrodactylid fauna infecting poeciliid fish, Zootaxa 2509, pp. 1-29 : 22

Gyrodactylus poeciliae Harris & Cable, 2000

( Figure 21 ; Tables 4 and 7)

Type host: Poecilia caucana Steindachner (“Cauca molly”, “piponcita”).

Site of infection: Body surface.

Type locality: La Concepción, Venezuela.

Type material examined: Holotype ( BMNH 1999.4.12.1).

Comments: The marginal hook sickles of G. poeciliae are arguably most similar to those of G. costaricensis in having a large, deep, approximately triangular shaped base, a proportionately narrow, slightly forward angled shaft and a short tip. Thus, the discrimination of G. poeciliae , based on marginal hook morphology, follows the comments provided for G. costaricensis .
