Morphological variation in the tropical anole, Anolis casildae (Squamata: Polychrotidae).

Abstract

Nosotros describimos la variación morfológica (escamación y coloración) observada entre ocho individuos de la especie de lagartija panameña Anolis casildae. Esta variación no fue observada en el holotipo y ayuda en la identificación de esta especie recientemente descrita (originalmente descrita con base en un único especimen macho). Esta especie ocurre solo en la Reserva Forestal Fortuna (Provincia de Chiriquí) y en el Bosque Protector Palo Seco (Provincia de Bocas del Toro) adyacente, en el oeste de Panamá. Anolis casildae se puede distinguir de las demás especies panameñas de Anolis por seis características: (1) dos escamas superciliares agrandadas (la primera más grande que la segunda); (2) una escama nasal anterior en contacto con la escama rostral o separada de ésta por una escama; (3) seis-ocho escamas sublabiales hacia el centro del ojo; (4) tres-cuatro escamas entre los semicírculos supraorbitales; (5) coloración única (cuatro-seis bandas café oblicuas interespaciadas por parches amarillos bordeados de azul; la papada es de color crema sucio con filas anchas de escamas amarillas interespaciadas irregularmente con escamas verde esmeralda más pequeñas) y (6) A. casildae ocurre de 1 050 a 1 400 m en la Cordillera Central. Nosotros también comparamos nuestras observaciones de historia natural de A. casildae con un Anolis similar grande, A. frenatus, una especie a la que nosotros creemos está A. casildae cercanamente relacionada.

We describe morphological variation (scalation and coloration) observed among eight individuals of the Panamanian lizard species Anolis casildae. This variation was not observed in the holotype and aids in identification of this recently described species (originally described on the basis of a single, male specimen). This species occurs only in the Reserva Forestal Fortuna (Chiriquí Province) and the adjacent Bosque Protector Palo Seco (Bocas del Toro Province) in western Panama. Anolis casildae can be distinguished from all other Panamanian anole species via six features: (1) two enlarged superciliary scales (the first larger than the second); (2) an anterior nasal scale in contact with the rostral scale or separated from the rostral by one scale; (3) 6–8 sublabial scales to the center of the eye; (4) 3-4 scales between the supraorbital semicircles; (5) unique coloration (4–6 oblique brown bands interspersed by blueoutlined yellow patches; dewlap is a dirty cream color with broad yellow scale rows irregularly interspersed with smaller emerald green scales) and (6) A. casildae occurs from 1 050 to 1 400 m in the Cordillera Central. We also compare our natural history observations of A. casildae to a similar large anole, A. frenatus, a species which we believe A. casildae to be closely related.
