      Translated title: Multiple lines of evidence show that Phymaturus agilis Scolaro, Ibargüengoytía & Pincheira-Donoso, 2008 is a junior synonym of Phymaturus spectabilis Lobo & Quinteros, 2005

          Abstract

          En 2005 Lobo y Quinteros describieron Phymaturus spectabilis de la Provincia de Río Negro, Argentina. La especie fue caracterizada, como lo mas notable, por contar con en un fondo general castaño de un patrón más oscuro que delimita manchas castañas claras dispuestas simétricamente en la cabeza, cuerpo extremidades y cola. En el 2008, Scolaro et al. describieron Phymaturus agilis de una localidad 22 km al sur de la localidad tipo de P. spectabilis. Se indicó diferir de P. spectabilis por su casi uniforme color castaño y por ciertas características merísticas y morfométricas. En 2009 colectamos, en la localidad tipo de P. agilis, cinco adultos (ambos sexos) con el patrón manchado oscuro de P. spectabilis, y cinco adultos (ambos sexos) con el color uniforme de P. agilis. Subsecuentemente una de las hembras con el patrón de P. spectabilis dio a luz dos individuos, uno con el patrón de P. agilis, el otro con el patrón de P. spectabilis. Nosotros no encontramos diferencias significativas entre los individuos con los dos patrones para nueve variables morfológicas, exhibiendo superposición los rangos de las variables morfológicas de los patrones. Nosotros concluimos que P. agilis es un sinónimo de P. spectabilis.

          Translated abstract

          Lobo and Quinteros (2005) described Phymaturus spectabilis from Río Negro Province, Argentina. The species was characterized most notably by having a brown background with a more-or-less bilaterally symmetrical pattern of bold, light tan markings, some enclosing small brown spots, on the head, limbs, body, and tail. In 2008, Scolaro et al. described P. agilis from a locality 22 km south of the type locality of P. spectabilis. It was reported to differ from P. spectabilis in its nearly uniform brown color and certain morphometric and meristic characteristics. In 2009 we collected, at the type locality of P. agilis, five adults (both sexes) with the bold pattern of P. spectabilis, and five adults (both sexes) with the uniform color of P. agilis. Subsequently, one of the females with the P. spectabilis pattern gave birth to two individuals, one of which had the pattern of P. agilis, the other with the pattern of P. spectabilis. Our analyses of specimens assignable to P. agilis and P. spectabilis detected no significant differences between individuals with the two patterns for nine morphological variables (including those used to diagnose P. agilis), with overlap in the ranges of the variables for both patterns. We therefore conclude that P. agilis is a junior synonym of P. spectabilis.
