Localities. CHIAPAS: Ríon Pijijiapan. GUERRERO: Laguna Chautengo. NAYARIT: Laguna la Tovara, San Blas. SINALOA: Laguna el Huizache, Laguna el Caimanero. TAMAULIPAS: Punta Piedra, Laguna Madre. VERA- CRUZ: Laguna la Rivera, Laguna Tamiahua, Río Tecolutla.

Specimens deposited. CNHE 7169, 7170, 7171.

Remarks. The trematodes found in the anterior region of the intestine of Eudocimus albus in nine localities of Mexico were identified as Parastrigea diovadena based on morphological characters. The measurements of some organs of our material are slightly smaller than those reported in the original description by Dubois & Macko (1972). This species of trematode seems to be specific for the white ibis, because it has only been recorded in this host in some localities of Cuba ( Dubois & Macko 1972) and Florida ( Forrester & Spalding 2003). In the current study, P. diovadena is recorded for the first time in Mexico, extending the geographical distribution range of this trematode.
