title: [Bothrops ophryomegas Bocourt (Serpentes: Viperidae) in Costa Rica: distribution, lepidosis, sexual variation and karyotype].
abstract: The distribution, karyotype and morphological characteristics of Bothrops ophryomegas from Costa Rica are described. This species presents a conspicuous sexual dimorphism and dichromatism. It is distributed in the dry forest areas of Guanacaste and Puntarenas. Its karyotype is indistinguisable from those described for other crotaline species.
