New geographic records and color variation of Dendropsophus pseudomeridianus (Amphibia, Anura, Hylidae) in the State of Rio de Janeiro, Brazil
Abstract
In this paper, we present the new records of Dendropsophus pseudomeridianus in the State of Rio de Janeiro, Brazil, obtained through field samplings in several areas of the Atlantic Rain Forest in that state. Herein are also presented the color variations of the species. Dendropsophus pseudomeridianus was collected in the costal lowlands of northern Rio de Janeiro and the capital’s metropolitan region, in the state’s northwest inland localities, in Serra do Desengano and Vale do Paraíba do Sul near the border with the state of Minas Gerais. This species was found in swamps in areas of semideciduous seasonal forest and dense ombrofilous forest. The new records provide a significant enhancement of the known geographic distribution of D. pseudomeridianus, filling in its gaps and providing evidence that the species is widely distributed throughout the state. The collected specimens exhibited color variation, dorsally they had only punctuations and small brown spots, oblique bars, and interocular stain or an extensive “X” shaped stain, and the upper lip adorned with white color punctuations, bars, or circular spots.
