Paracreptotrema heterandriae n. sp. (Trematoda: Allocreadiidae) is described from the intestine of the freshwater fish Heterandria bimaculata (Teleostei: Poeciliidae) from the upper basin of Rio La Antigua, in Veracruz, Mexico. The new species is distinguished from the 3 others in the Paracreptotrema Choudhury, Perez-Ponce de Leon, Brooks, and Daverdin, 2006, mainly by having a feeble membranous cirrus sac containing an uncoiled seminal vesicle, instead of a well-developed muscular cirrus sac that encloses coiled seminal vesicle, pars prostatica, and ejaculatory duct as in the previously 3 nominal species. Moreover, eggs of the new species are larger than all others ([measurements in micrometers] eggs of P. heterandriae n. sp. 72.5 [70-75] x 40 [35-41]; P. blancoi 55.4 [52.5-62.5] x 38.5 [32.5-42.5]; P. mendezi 46 x 37; P. profundulusi 57 [52-60] x 27.8 [25-30]).
