Se describe Eleutherodactylus cadenai sp. nov. de las selvas de la vertiente occidental de la Cordillera Occidental de Colombia corregimiento .de Murrí, Municipio de Frontino, Antioquia.  La especie parece tener un ancestro común con Eleutherodactylus ingeri de los bosques nublados de la Cordillera Oriental de Colombia y las dos tienen parentescos con Eleutherodactylus ruizi de las cordilleras Central y Occidental de Colombia., The broad-headed eleutherodactyline frogs have been studied by Lynch1975, 1981. Although frogs of this assembly are easily identified Lynch,1975, 1976, 1981, the assembly is not a natural group Lynch, 1986.Recently, Rivero 1984 described a new species, E. sernai, from westernAntioquia, Colombia. Although Rivero associated E. sernai with thebiporcatus group, the species appears to be a member of the sulcatus groupbecause it possesses the plesiornorphic condition of the mandibular musclesadductors and the trigeminal nerve mandibular ramus. However, this characteristicis not sufficient to place E. sernai within the sulcatus group; theassignment will be defended in a future paper on the osteology of the variousspecies of the group. For the moment, the sulcatus group contains thefollowing species: E. cerasies Lynch, E. cornutus Jimenez de la Espada,E. helonotus Lynch, E. ingeri Cochran and Gain, E. ruizi Lynch, E.sernai Rivero, and E. sulcatus

A NEW SPECIES OF BROAD-HEADED ELEUTHERODACTYLUS FROM THE CORDILLERA OCCIDENTAL OF COLOMBIA (AMPHIBIA, LEPTODACTYLIDAE) By JOHN D. LYNCH * SUMARIO Se describe Elewtherodcctylus cadenai sp.
nov.
de las selvas de la vertiente occidental de la Cordillera Occiclental de Colombia (corregimiento .de Murri, Municipio de Frontino, Antioquia). La especie parece tener un ancestro cornun con Eleutherodactylus i11geri de los bosques nublados de la Cordillera Oriental de Colombia y las dos tienen parentescos con Eleutkerodactylus rnizi de las cordilleras Central y Occidental de Colombia. The broad-headed eleutherodactyline frogs have been studied by Lynch (1975, 1981).
Although frogs of this assembly are easily identified (Lynch, 1975, 1976, 1981), the assembly is not a natural group (Lynch, 1986). Recently, Rivero (1984) described a new species, E.
sernai, from western Antioquia, Colombia.
Although Rivero associated E.
sernai with the biporcatus group, the species appears to be a member of the sulcatus group (because it possesses the plesiornorphic condition of the mandibular muscles adductors and the trigeminal nerve mandibular ramus.
However, this characteristic is not sufficient to place E.
sernai within the sulcatus group; the assignment will be defended in a future paper on the osteology of the various species of the group.
For the moment, the sulcatus group contains the following species: E.
cerasies Lynch, E.
cornutus (Jimenez de la Espada), E.
helonotus (Lynch), E.
ingeri (Cochran and Gain), E.
ruizi Lynch, E. sernai Rivero, and E.
sulcatus (Cope). * Profesor visitante (Fulbright), Programa post-grado en sistematica, Instituto de Ciencias Naturales, Universidad Nacional de Colombia; direcci6n permanente, School of Biological Sciences, The University of Nebraska, Lincoln, Nebraska, 68588 USA. 504 CALDASIA, VOL. xv, Nos.
71-75 OCTUBRE 30 DE 1986 At present, we do not know if the group is monophyletic.
In a study of part of the group, Lynch (1981) proposed a...
