Sibon perissostichon sp. nov. pan köhler et al. 2010

  1. 1. Herpetologica, 66(1), 2010, 80–85E 2010 by The Herpetologists’ League, Inc. A NEW SPECIES OF SIBON (SQUAMATA: COLUBRIDAE) FROM WESTERN PANAMA GUNTHER KOHLER1,3, SEBASTIAN LOTZKAT1,2, ¨ AND ANDREAS HERTZ1,2 1 Senckenberg Forschungsinstitut und Naturmuseum, Senckenberganlage 25, D-60325 Frankfurt am Main, Germany 2 Johann Wolfgang Goethe-University, Institute for Ecology, Evolution and Diversity, BioCampus—Westend, Siesmayerstr. 70, 60323 Frankfurt am Main, Germany ´ ABSTRACT: We describe a new species of Sibon from the Reserva Forestal La Fortuna, Chiriquı Province, Panama. The new species is distinguished from all species presently assigned to Sibon by having 17 rows of dorsal scales at midbody and 15 rows one head length anterior to cloaca (vs. 13 or 15 rows of dorsal scales at midbody without reduction on posterior portion of body in all other species of Sibon), and dorsal scale rows that change orientation from the sides of body toward middorsum (vs. maintaining more or less the same orientation). A key to the Lower Central American species of Sibon is provided. RESUMEN: Describimos una nueva especie de Sibon procedente de la Reserva Forestal La Fortuna, ´ ´ Provincia de Chiriquı, Panama. La nueva especie se diferencia de todas las especies actualmente asignadas al ´ genero Sibon por tener 17 hileras de escamas dorsales en la mitad del cuerpo y 15 hileras una longitud de ´ ´ cabeza anterior a la cloaca (13 o 15 hileras de escamas dorsales en la mitad del cuerpo sin reduccion en la ´ ´ parte posterior del cuerpo en todas las demas especies de Sibon), ası como hileras de escamas dorsales que ´ cambian su orientacion desde los flancos del cuerpo hacia el centro del dorso (conservan su orientacion ´ ´ longitudinal en todas las demas especies de Sibon). Presentamos una clave para las especies de Sibon que ´ ocurren en el sur de Centroamerica.
