Abstract

Based on published records and original data, we present a checklist of metazoan parasites of Mexican amphibians andreptiles. This checklist includes information for 430 nominal taxa of metazoan parasites, 371 helminths (137 trematodes,10 monogeneans, 29 cestodes, 14 acanthocephalans, 173 nematodes, and 8 hirudineans), 51 acari and 8 crustaceans. Weadd 184 new locality records to Acari. These data represent the current knowledge on metazoan parasites of 68 amphibi-ans and 219 reptile species of Mexico.

Key words: Mexico, amphibians, reptiles, parasites, helminths, Acari



Introduction

Parasitism is common in nature, and has arisen many times in the evolutionary history of different groups. Forexample, metazoan parasites of amphibians and reptiles are distributed in five phyla: Platyhelminthes (Trema-toda, Monogenoidea and Cestoidea), Acanthocephala, Nematoda, Annelida (Hirudinea), and Arthropoda(Acari and Crustacea).

Although Mexico has a large number of amphibian and reptiles, occupying the second place in global rep-tilian diversity (804 species), and the fourth in amphibians (361) (Flores-Villela & Canseco-Márquez, 2004),the knowledge about their metazoan parasite fauna is still far from complete. The majority of studies aboutparasites are isolated records included in descriptions of new species (e.g. Bravo-Hollis, 1943c; Caballero,1944a; Hoffmann, 1965), general catalogues (Lamothe-Argumedo et al., 1997) and checklists (e.g. Hoffmann,1969; Hoffmann & López-Campos, 2000). This information is scattered because it has been published in dif-ferent kinds of sources, from specialized to local journals as well as theses, with limited distribution. The maingoal of the present study is to provide a comprehensive compilation of information on the metazoan parasitesthat inhabit the amphibians and reptiles of Mexico. To do so, we compiled all existing records, made taxo-nomic changes and synthesized locality data. This information will greatly aid taxonomist working on para-sites of Mexico by providing a much needed update on taxonomic status, distribution, and host records.

Materials and Methods

The information used to create this checklist is updated until April, 2008, and comes from two differentsources: 1) retrospective bibliographical search, using different databases such as CAB Abstracts, BiologicalAbstracts, and Zoological Record; 2) Search in the data bases of national [Colección Nacional de Helmintos(CNHE), and Colección Nacional de Ácaros (CNAC), Instituto de Biología, UNAM, Mexico City, Mexico]and international [Harold W. Manter Laboratory of Parasitology (HWML), University of Nebraska-Lincoln,U.S.A., United States National Parasite Collection (USNPC), Beltsville, Maryland, U.S.A.] parasite collec-tions.

The checklist is divided in two sections; the first includes a parasite-host list, presented in phylogeneticorder starting with the phylum Platyhelminthes (Trematoda, Monogenoidea and Cestoidea), and followed bythe phyla Acanthocephala, Nematoda, Annelida (Hirudinea) and Arthropoda (Acari and Crustacea). Eachphylum contains families, genera, and species in alphabetical order. The nomenclature and classification foreach metazoan group is based on the following references: Trematoda (Yamaguti, 1971; Jones et al., 2002;Gibson et al., 2005), Monogenoidea (Boeger & Kritsky, 1993), Cestoidea (Khalil et al., 1994), Acanthoceph-ala (Amin, 1985), Nematoda (Anderson et al., 1974-1983), Hirudinea (Sawyer, 1986; Davies, 1991), Acari(Evans, 1992), Crustacea including Pentastomida (Martin & Davis, 2001). Information for each speciesincludes species name, authority, host group, developmental stage of parasite in parentheses (A = adult, C =cistacanth, L = larva, N = nymph and M = metacercariae), and finally habitat. We use “NA” when some dataare not availables in the original source. Then we present species distribution, referring state of the MexicanRepublic (in caps) and locality name, followed by host species and references.

Type host, locality and original reference for new species described from Mexican hosts are indicated inbold font; type material deposition in a collection is indicated with H (=Holotype) and P (=Paratype) after col-lection acronym. When deposition of specimens is not indicated in the original source, the section “Specimensdeposited” is omitted. Finally, notes about important taxonomic considerations are presented when it is neces-sary to clarify the current species status. New locality and/or taxonomic records are presented in a separateparagraph following the same format described above. Voucher specimens are indicated by the collectionacronym and the relevant accession number(s).

The second section contains the host-parasite list, which is taxonomically and alphabetically organized,following the phylogenetic order of host groups. Host names are in accordance with Flores-Villela (1993),Flores-Villela and Canseco-Márquez (2004), Frost et al. (2006), and Frost (2007). Host names changed byFrost et al., (2006) and Frost (2007) are followed by the most recent junior synonym. Bibliographic references



for all records and all taxonomic notes are presented in the final section. The complete list of localities wheremetazoans have been collected is presented, as well as the geographical coordinates for most of them as wererecorded in the literature. When possible, additional geographic information was obtained using maps (scale1:50 000), electronic pages such as Geolocate and Fuzzyg, and the software Biotica 4.5.

Results

In the present checklist, 430 nominal taxa of parasitic metazoans are listed, 371 pertaining to helminths (137trematodes, 10 monogeneans, 29 cestodes, 14 acanthocephalans, 173 nematodes, and 8 hirudineans), 51 toacari and 8 to crustaceans. These data represents the current knowledge on metazoans parasites recorded in 68amphibians and 219 reptile species of Mexico.

Specimens deposited: USNPC (42047)(P).Notes: The original name for this species, Aplectana mexicana (Walton, 1940), was changed to Aplectana

waltoni because the first species is homonym of the species described by Caballero (1933). According toBaker (1987), this species cannot be classified with certainty to Aplectana. Holotype lost. The host wasoriginally identified as Bufo simus; however, the distribution of B. simus is restricted to South America. InMexico, the specimens conferred to B. simus correspond to Rhinella marina, but R. marina does not occur inthe Distrito Federal (García-Vásquez com. pers.). The most likely scenario is that the host was misidentified.

Discussion

In this paper we list 430 taxa of parasites associated with 68 amphibian and 219 reptile species in Mexico. Themajority of these parasite species are nematodes (173 species, 40.1%) and trematodes (137, 31.8%), togetherencompassing about 71.9% of the parasite fauna. Less common are Acari (51, 11.9%), cestodes (29, 6.74%)and acanthocephalans (14, 3.25%). Monogeneans (10, 2.3%), hirudineans (8, 1.9%) and crustaceans (8,1.85%) are rare. As noted by previous authors, the level of association of a given host group with aquatic hab-itats determines the richness of each one of these parasite groups (Brandt, 1936; Prokopic & Krivanec, 1975;Brooks, 1976). Parasite records from terrestrial amphibian and reptile species (as in lizards) involve mostlynematodes and acari with direct life cycles, while trematodes are more common in hosts that live primarily inaquatic habitats (as in turtles and colubrids). The host species with the largest number of parasite species aresemiaquatic: Rhinella marina with 49 species, Lithobates vaillanti with 34 and L. montezumae with 30.According with Aho (1990) this high species richness is the result of the fact that these hosts spend time inwater during their larval stages and their breeding periods, being exposed to trematodes and cestodes that aretypically transmitted through the ingestion of aquatic invertebrates, while also spending time out of the water,being exposed to the skin penetration by nematode larvae, infestation with acari, and inoculation of nema-todes by flying vectors.

The three biogeographic groups of parasite species characterized by Pérez-Ponce de León et al. (2000),Nearctic, Neotropical and endemic, can be distinguished in our list. In some cases, parasite biogeographicaffinities coincide with host affinities, showing some degree of evolutionary association. For example, themexican species of leopard frogs examined for parasites (Lithobates berlandieri, L. brownorum, L. dunni, L.forreri, L. magnaocularis, L. megapoda, L. montezumae, L. neovolcanica, L. spectabilis), show a parasitefauna with 50% of the adult species (26 out of 52) having nearctic affinities, following the origins of the hostgroup (Hillis et al., 1983; Hillis & Wilcox, 2005); a minority of the parasite fauna of this group of frogs (19 %of the adult species) has Neotropical affinities (for example, frogs from the Lithobates palmipes group). Animportant component of the parasite fauna of Mexican leopard frogs is constituted by endemic elements(31.4% of the adult species), that have probably speciated with their hosts. Leopard frogs biogeographic his-tory is very complex, resulting in a high species richness in Mexico (Hillis et al., 1983; Zaldívar-Riverón etal., 2003). Some groups of parasites that are specific to this group of frogs have probably co-speciated withthem. For example, this appears to be the case for species of the lung trematodes Haematoloechus spp., where6 endemic species have been described (and more have been detected using molecular characters, León-Règagnon, 2003), and Glypthelmins spp., with two. Nematodes have been less studied, but it has already beensuggested that records of Rhabdias sphaerocephala in Mexican leopard frogs actually belong to an endemicspecies not yet described (Martínez-Salazar pers. com.). Phylogenetic studies using DNA sequences may



show a higher percentage of endemic species in the parasite fauna of amphibians and reptiles in Mexico. Thishighlights the importance of incorporating molecular systematics in the completion of species inventories inpoorly studied groups as are the helminths and acari parasites of wild fauna (León-Règagnon, 2003).

Mites and ticks show different grades of host specificity; the most common parasitic mite of amphibiansand reptiles is the chigger Eutrombicula alfreddugesi which has been collected in Mexico on one species offrogs, 29 lizards, 4 snakes, and many other terrestrial vertebrates. On the other hand, some species are highlyspecific to different host genera, for example, Geckobia leonilae to Phyllodactylus and Hirstiella otophila toColeonyx (Hunter & Loomis, 1966; Hoffman & Morales-Malacara, 1986; present study).

Among the Ixodidae, Amblyomma dissimile, A. rotundatum, A. sabanerae and A. scutatum have been ref-ered to as specialists of amphibians and reptiles. Although A. dissimile has been mostly associated to reptiles,we found that it also parasitizes amphibians especially Rhinella marina. All of these species are typicallyNeotropical although Oliver et al. (1993) indicates that A. rotundatum has become established in the UnitedStates (Nearctic region). The transmission of all of these species is favoured by the fact that the hosts aremainly terrestrial or pass most of their life cycle out of water. On the other hand, the tick Amblyomma cajenn-ense is a generalist species associated with a wide variety of terrestrial vertebrates, including mammals andbirds (Barros-Battesti et al., 2006). The few records on amphibians and reptiles could be considered as acci-dental infestations.

Only 287 (24.6%) of the total number of species of amphibians and reptiles reported in Mexico (1165)(Flores-Villela & Canseco-Márquez, 2004), have been surveyed for parasites so far. This suggests that ourknowledge about parasites of amphibians and reptiles in Mexico is still far from complete. This is most evi-dent in Acari which have been recorded from only 115 species of amphibians and reptiles. Moreoever, themajority of these hosts have only one mite parasite species, Eutrombicula alfreddugesi (in nature) or Ophy-onyssus natricis (in captivity). There are 361 amphibian and 804 reptile species in Mexico, and mites andticks have been collected from only 4.1 % (15 species) of amphibians and 11.4 % (92 species) of reptile spe-cies. Hoffmann and López-Campos (2000) recorded 2343 species of Acari in Mexico but only 51 (2.2 %) areparasites of amphibians and reptiles.

The parasite fauna is an important component of the natural history of the host organisms that can be usedas a powerful and predictable tool to support biodiversity studies and conservation initiatives (Brooks et al.,2001; Hoberg, 1996, 1997). Because of their complex life cycles, parasites provide information about trophicwebs of their hosts and about the entire ecosystem. Knowledge about parasite species that are common toamphibians and reptiles of a particular region can be of crucial value in the study of the condition of popula-tions of these hosts and in the planning of conservation strategies, in effect using parasites as “sentinel” spe-cies (Brooks, 2003). This tool is particularly valuable considering that many of the amphibian and reptilespecies are endangered. If we find that a particular amphibian or reptile population is free from their typicalparasites, we can be sure that the ecosystem is in very poor condition and that the host population is severelythreatened, because minimum conditions for the completion of the parasites life cycles (water quality or inter-mediate hosts populations) are absent. On the other hand, if unexpected parasites are present, they can be con-sidered as potential emerging infectious diseases for the native host populations under stress conditions(Brooks & Ferrao, 2005; Brooks et al., 2006).

The unequal representation of metazoan species in amphibians and reptiles from Mexico highlights thenecessity to increase the sample effort considering the diversity of these host groups. Early actions can pre-vent major problems of local extintions as have been the case for many amphibian species (Lipps et al., 2005).For these reasons it is essential that specialists of different disciplines work as a team in integrated studies ofparasite groups; only in this way can we take maximum advantage of biological material, time and financialresources in our efforts to know and preserve the herpetological fauna.
