“…The helminth diversity of the Papaloapan basin in terms of taxonomic groups coincides with a wellknown pattern for helminth communities in freshwater fish in Mexico, with nematodes and trematodes being more abundant Salgado-Maldonado et al 2001a, b, 2004a, b, 2005Aguilar-Aguilar et al 2003c;Sa´nchez-Nava et al 2004). Remarkably, the Papaloapan basin also has an abundant monogenean component compared to the reported abundances in other Mexican hydrological basins.…”

“…Though knowledge on the helminth fauna of freshwater fish in Nicaragua is still incipient, current records show them sharing 28 helminth species (33%) with the fish of the Papaloapan (see Aguirre-Macedo et al 2001a, b;Vidal-Martı´nez et al 2001b;Mendoza-Franco et al 2003a). In contrast, only 19% of the helminth species in the Balsas River basin are shared with the fish of the Papaloapan (see Salgado-Maldonado et al 2001a). The Balsas River basin is adjacent the Papaloapan basin, but drains the western side of the Continental Divide, towards the Pacific Ocean.…”

“…To date, helminth parasite inventories have been published for the freshwater bodies of the Yucata´n Penı´nsula (Moravec et al 1995a, b;Scholz et al 1995aScholz et al , b, 1996bMendoza-Franco et al 1999;Kritsky et al 2000), the Balsas (Salgado- , Lerma and Santiago (SalgadoMaldonado et al 2001b) and Pá nuco river basins (Salgado-Maldonado et al 2004a), the Ayuquila River in the Sierra de Manantla´n, Jalisco (Salgado- Maldonado et al 2004b), water bodies in the Sierra Madre Oriental (Aguilar-Aguilar et al 2004), and the lowlands in the state of Tabasco drained by the Grijalva-Usumacinta system . Helminth inventories have also been published for some fish families, particularly for the cichlids (Salgado- Vidal-Martı´nez et al 2001a), poecilids and goodeids .…”

A checklist based on previously published records and original data is presented for the helminth parasites reported in 35 fish species from nine families from the Rio Papaloapan basin, east Mexico. The checklist contains 85 taxa from 39 helminth families. Trematodes and nematodes were the most abundant taxonomic groups. The helminth fauna in the fish of the Papaloapan River basin predominantly consists of Neotropical species that are largely autogenic. The introduced species Centrocestus formosanus was the most widely distributed helminth, infecting 16 host species. Ten of the recorded helminth species have only been found in fish from the Papaloapan. This inventory contributes 157 new host records, and reports the presence of 30 helminth species in the Papaloapan for the first time . This inventory shows the richness of helminth parasite species in the fish of the Papaloapan River basin in comparison with the other hydrological basins in Mexico. It also demonstrates that this fauna is typically Neotropical and quite similar to that from the neighboring basins of the Grijalva-Usumacinta system and the Yucatan Peninsula. The data also suggest highly effective transmission between environments within the same basin and that the regional parasite fauna is strongly influenced by fish community composition.

Diaphorocleidus orthodusus n. sp. and Diaphorocleidus kabatai (Molnar, Hanek and Fernando, 1974) Jogunoori, Kritsky, and Venkatanarasaiah, 2004 are detailed from Astyanax orthodus and Astyanax aeneus, respectively. Palombitrema heteroancistrium (Price and Bussing, 1968) is described from specimens collected from A. aeneus, and Urocleidoides strombicirrus (Price and Bussing, 1967) is reported for the first time from A. aeneus and Astyanax fasciatus in Panama. Characithecium costaricensis (Price and Bussing, 1967) n. comb. is detailed based on specimens from A. aeneus. Characithecium costaricensis is characterized by having overlapping gonads, a medioventral vaginal aperture, a copulatory complex consisting of single counterclockwise coil of the copulatory organ that is articulated to the accessory piece, and a haptor having 2 pairs of anchors, dorsal and ventral bars, and 14 hooks. Measurements of body size varied substantially among individual worms, both within and across different host species and locations. However, the morphological differences were insufficient to separate species of Characithecium. This result suggests limited parasite speciation across sympatric species of Astyanax in Mexico and Panama.Urocleidoides Mizelle and Price, 1964, was erected for a species that infected Poecilia reticulata (Poeciliidae) in a California aquarium. Mizelle et al. (1968) emended it by adding gonads overlapping or tandem, male copulatory organ coiled with a single or multiple rings, 1 or 2 prostatic reservoirs, and vaginal pore on the left side of the body or absent. Urocleidoides included species from fishes in 5 orders (Atheriniformes, Characiformes, Gymnotiformes, Perciformes, and Siluriformes) until Kritsky et al. (1986) (2007). Additional specimens were mounted unstained in Gray and Wess's medium to examine the sclerotized structures. Measurements, all in micrometers (m), represent straight-line distances between extreme points and are expressed as the mean followed by the range and number (n) of structures measured in parentheses; body length includes the haptor. Numbering of hook pairs follows Mizelle (1936) and Mizelle and Price (1963).
