(1987), Savage, J.M. (1987)Data Providers: Paul Walker, Manuel Acevedo, Gustavo Cruz, Larry David Wilson, Randy McCranie, Gunther KöhlerCraugastor laticeps (Duméril, 1853)This species can be found on the Atlantic slopes of Mexico, from southern Veracruz to Tabasco and Chiapas, andsouthwards to western Belize, Guatemala, and northern Honduras, from 10-1,500m asl. It is uncommon in Belize andGuatemala, and rare in Mexico. There are few localities known for Honduras. Recent surveys in Oaxaca, Mexico,indicate that it has disappeared from some localities. It occurs in leaf-litter in lowland and premontane tropicalforest and is tolerant of moderate habitat alteration (it occurs in cacao and shade-coffee plantations in Honduras).Reproduction is by direct development. Forest destruction and the conversion of forest to shaded crops are lowthreats, although subsistence agriculture is a threat in Honduras. The recent declines in Oaxaca could be due tochytridiomycosis. It occurs in several protected areas throughout its range. Further work should be conducted todetermine whether or not the recent declines are due to chytridiomycosis. It is protected by Mexican Law under the“Special Protection” category (Pr).Taxonomy: This species was previously within the genus Eleutherodactylus (Crawford and Smith 2005).Bibliography: Campbell, J.A. (1998), Crawford, A.J. and Smith, E.N. (2005), Lee, J.C. (1996), Lips, K.R. et al. (2004), McCranie, J.R. andWilson, L.D. (2002b), Savage, J.M. (1987)Data Providers: Georgina Santos-Barrera, Manuel Acevedo, Paul Walker, Julian Lee, Gustavo Cruz, Larry David WilsonCraugastor rostralis (Werner,1896)This species is known from extreme eastern Guatemala near the Honduran border, and from the following localitiesin western and north-central Honduras: Cerro Quebrada Grande, Montana Pico Pijol, Montana La Fortuna, MontanaPortillo Grande, Parque Nacional Cusuco, and Montana Merendon west of San Pedro Sula. Its altitudinal range is1,050-1,800m asl. This is a moderately common species. It lives on the forest floor in premontane and lower montanewet forest, and also occurs in degraded forest and coffee plantations (but not in more open habitats). It presumablybreeds by direct development. The major threat to this species is severe habitat loss due to agricultural development,livestock grazing, logging, human settlement, and fire. It occurs in Parque Nacional Cusuco and Parque NacionalTexiguat in Honduras, but not in any protected areas in Guatemala.Taxonomy: This species was previously within the genus Eleutherodactylus (Crawford and Smith 2005).Bibliography: Campbell, J.A. (2001), Crawford, A.J. and Smith, E.N. (2005), Dunn, E.R. and Emlen, J.T. (1932), McCranie, J.R. andWilson, L.D. (2002b), Savage, J.M. (1987), Stuart, L.C. (1963)Data Providers: Gustavo Cruz, Larry David Wilson, Randy McCranie, Manuel AcevedoCraugastor yucatanensis (Lynch, 1965)This species is endemic to the Yucatan Peninsula, in east-central Yucatan and north-central Quintana Roo, Mexico.The type locality is 10m asl. It is rarely encountered but is occasionally locally common. Its habitat is lowland tropicalsemi-deciduous and deciduous forest. It is both terrestrial and arboreal and is sometimes found in caverns and cenotes.Breeding is by direct development. The major threats to this species is habitat loss and disturbance due to touristactivities, in particular along the Quintana Roo Mayan area. A portion of this species’ range is within the Reserva dela Biósfera Sian Ka’an, which affords it some protection. Protection of the original forest in the Yucatan Peninsula isalso recommended. This species is protected by Mexican Law under the “Special Protection” category (Pr).Taxonomy: This species was previously within the genus Eleutherodactylus (Crawford and Smith 2005).Bibliography: Campbell, J.A., Lamar, W.W. and Hillis, D.M. (1989), Crawford, A.J. and Smith, E.N. (2005), Lee, J.C. (1996), Lee, J.C. (2000)Data Providers: Julian Lee, Rogelio Cedeño VázquezCrossodactylodes bokermanni Peixoto, 1983 “1982”This species is known only from two localities in south-eastern Brazil at around 650m asl in the state of EspíritoSanto: Santa Teresa and Castelo. It presumably occurs between these two localities, and probably more widely. It isa common species. It is confined to forest, where it is arboreal, living in epiphytic bromeliads. Breeding is by larvaldevelopment in bromeliads. The major threat is habitat loss, especially due to the collection of bromeliads, andalso due to agricultural development, wood plantations, livestock grazing, logging, human settlement and tourism,though some of its habitat is quite well protected. It occurs in the Reserva Biológica Augusto Ruschi and ParqueEstadual do Forno Grande.Bibliography: Gomes, N. (1988), Peixoto, O.L. (1982)Data Providers: Débora Silvano, Oswaldo Luiz PeixotoCrossodactylodes izecksohni Peixoto, 1983 “1982”This species is known only from the vicinity of Santa Teresa, in the state of Espírito Santo, south-eastern Brazil, at675m asl, although it might occur more widely. It is a common species. Its habitat is terrestrial and epiphytic bromeliadsnear the ground inside forests and on the forest edge, but not in more degraded habitats. Breeding is by larvaldevelopment in bromeliads. The area where it is found is quite well protected (as a biological reserve), but habitatloss is taking place nearby, due to agricultural development, wood plantations, bromeliad-collecting, logging, humansettlement and tourism. It occurs in the Reserva Biológica Augusto Ruschi.Bibliography: Gomes, N. (1988), Peixoto, O.L. (1982)Data Providers: Débora Silvano, Oswaldo Luiz PeixotoCrossodactylus schmidti Gallardo, 1961This species can be found from 300-750m asl in Misiones, Argentina; Tres Baras de Paraná, Paraná, Brazil (here, itsrange is severely fragmented); and Itapua Department, Paraguay. It is common in its limited range. It occurs nearpermanent streams (in which it breeds) in rainforest, and probably does not tolerate habitat disturbance. Threats tothis species include selective logging, clear-cutting of primary forests, pollution of soil and water due to agriculturalpractices, and industrial pollution by organic wastes. The introduction and spread of Rana catesbeiana is also a threatto this species. It occurs in Parque Estadual Rio Guarani, Brazil, and in Argentina in the Reserva de la Biósfera Yabotí,Parque Nacional Iguazú, and several provincial reserves.Bibliography: Cei, J.M. (1980), Faivovich, J. (1998), Gallardo, J.M. (1961a), Lavilla, E.O. et al. (2000), Lavilla, E.O. and Cei, J.M. (2001)Data Providers: Magno Vicente Segalla, Paulo Garcia, Débora Silvano, Esteban Lavilla, Diego BaldoCycloramphus brasiliensis (Steindachner, 1864)This species is known from the Serra dos Órgãos and Serra da Mantiqueira, in Rio de Janeiro State, Brazil, from800-1,200m asl. This is not a common species. It occurs on rock wall seeps and in forest streams in primary andgood quality secondary forest. Larvae have been observed on rocks that are covered with a fi lm of running water,either on exposed rocks in or next to streams. Habitat loss due to infrastructure development for human settlementis a major threat, and this is taking place in some protected areas, even though this is illegal. The range of thespecies includes several protected areas, but there remains a need for improved conservation and maintenanceof existing habitat.Bibliography: Bokermann, W.C.A. (1951), Heyer, W.R. (1983)Data Providers: Sergio Potsch de Carvalho-e-Silva, Ronald HeyerCycloramphus semipalmatus (Miranda-Ribeiro, 1920)This species is known from Serra do Mar in the state of São Paulo, in Brazil, from about 800m asl. This is a reasonablycommon species; however, there has been an unexplained decline over its whole range recently. It was once commonin Boracéia, but has been considered locally extinct there since 1988. This species is found under, or on top of, rocksin or next to small forest streams in primary and secondary forest. It presumably has larvae that are found on rocksthat are covered with a film of running water, either on exposed rocks in or next to streams, like other members ofthe genus. There is a steel works on the coast that pollutes the water, which might be affecting local populations.The reason for the observed decline is currently unknown, but chytridiomycosis cannot be ruled out. The range of thespecies includes a few protected areas. Further research into the cause of the recent declines is needed.Taxonomy: This species was removed from the synonymy of Cycloramphus asper by Heyer (1983).Bibliography: Bertoluci, J.A. and Heyer, W.R. (1995), Eterovick, P.C. et al. (2005), Heyer, W.R. (1983), Heyer, W.R. et al. (1988), Heyer,W.R. et al. (1990)Data Providers: Vanessa Verdade, Ronald HeyerEleutherodactylus alalocophus Roa-Trujillo and Ruíz-Carranza, 1991This species is known from the western flank of the central Andes in the departments of Quindío, Valle del Cauca,Caldas and Risaralda, Colombia, from 2,650-3,100m asl. It is a very common species in its small range. It occurson herbaceous vegetation or on humid rocks, about 20cm above the ground. It is possible to find individuals undersmall waterfalls or in small brooks covered by undergrowth, or under alder crops (Alnus acuminata) in the forest andforest edges. It has not been found outside forest habitat. Breeding is by direct development. There are no knownmajor threats to this species, since its habitat is relatively secure. Its range does not include any protected areas.It should be noted that some other species of Eleutherodactylus that are associated with streams have undergonedramatic declines and disappearances, possibly due to chytridiomycosis, so the status of this species should bemonitored carefully.Bibliography: Acosta-Galvis, A.R. (2000), Ardila-Robayo, M.C. and Acosta-Galvis, A. (2000a), Lynch, J.D. and Duellman, W.E. (1997),Lynch, J.D., Ruiz-Carranza, P.M. and Ardila-Robayo, M.C.

(1996)Data Providers: Fernando Castro, Maria Isabel Herrera, John LynchEleutherodactylus anolirex Lynch, 1983This species occurs in the northern Cordillera Oriental in the departments of Norte de Santander and Santander,Colombia, and nearby at Macizo de Tamá in Venezuela. Its altitudinal range is 1,900-3,550m asl. It is common inColombia, but there is little information on its population status in Venezuela. It is a cloud forest species, also livingin páramo grassland and sub-páramo bushland areas. Its ability to adapt to modified habitats is unknown. It is usuallyfound at night on low vegetation; during the day it hides under rocks, logs or among vegetation. It is presumed to bea direct developing species. The major threats are deforestation for agricultural development (including cultivationof illegal crops), logging, and human settlement, and pollution resulting from the spraying of illegal crops. Fire mightalso be a threat. However, it has a broad altitudinal range, and overall its habitats are probably not seriously threatened.The Venezuelan populations are within Parque Nacional El Tamá and the Estación Demonstrativo El Rasgon.Its occurrence in protected areas in Colombia is unclear.Bibliography: Acosta-Galvis, A.R.

(1996)Data Providers: Fernando Castro, Enrique La Marca, María Cristina Ardila-RobayoEleutherodactylus celator Lynch, 1976This species can be found in cloud forests from 1,750-2,800m asl, on the Pacific versant of the western Andes innorthern Ecuador and adjacent southern Colombia (Nariño Department). It is fairly common, or at least was so whenlast searched for in the mid-1980s. It is a nocturnal species that has been found in terrestrial bromeliads, and may beencountered on the sides of roads and in herbaceous vegetation, in leafy cloud forests. It is presumed to be a directdeveloping species although the site of egg deposition is not known. It is tolerant of habitat disturbance providedbromeliads are available. This species is threatened by deforestation occurring for a range of reasons, including loggingand agricultural development for the cultivation of crops (some of them illegal) and livestock grazing. In Ecuador, itsgeographic range overlaps with the Reserva Ecológica Cotacachi-Cayapas, and the Reserva Geobotánica Pululahua.It also occurs in the Reserva La Planada private reserve, Colombia.Bibliography: Acosta-Galvis, A.R. (2000), Lynch, J.D. (1976a), Lynch, J.D. (1998b), Lynch, J.D. and Burrowes, P.A. (1990), Lynch, J.D.and Duellman, W.E. (1997), Lynch, J.D., Ruiz-Carranza, P.M. and Ardila-Robayo, M.C.

Coloma, John LynchEleutherodactylus dimidiatus (Cope, 1862)This species is widespread in Cuba from 0-1,375m asl. It is moderately common in suitable habitat. This is a terrestrialspecies that requires closed mesic forest. It breeds by direct development and lays its eggs in damp leaf-litter. Themain threat to this species is habitat destruction as a result of deforestation due to agricultural development for cropcultivation and subsistence farming, charcoal manufacture, and infrastructure development for human settlement andtourism. Agricultural pollution is also a threat. This species occurs in many protected areas.Bibliography: Centro Nacional de Areas Protegidas (CNAP) (2002), Hedges, S.B. (1993), Hedges, S.B.

(1991)Data Providers: Blair Hedges, Luis DíazEleutherodactylus eileenae Dunn, 1926This species is widespread in western and central Cuba from 0-830m asl. It is a common species. It is found inclosed-canopy mesic forests, and is normally terrestrial but calls from arboreal sites. It has not been recorded outsideforest habitat. Eggs are laid on the ground, and it breeds by direct development. The major threats to this species areagricultural development and pollution, and infrastructure development for human settlement and tourism. It occursin several protected areas, although more effective protection is required for this species.
