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 westernAntioquia, Colombia. Although Rivero associated E. sernai with thebiporcatus group, the species appears to be a member of the sulcatus group(because 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
