A marvelous new glassfrog (Centrolenidae, Hyalinobatrachium) from Amazonian Ecuador

Resumen

<i>Hyalinobatrachium</i> is a behaviorally and morphologically conserved genus of Neotropical anurans, with several pending taxonomic problems. Using morphology, vocalizations, and DNA, a new species from the Amazonian lowlands of Ecuador is described and illustrated. The new species, <i>Hyalinobatrachium yaku</i><b>sp. n.</b>, is differentiated from all other congenerics by having small, middorsal, dark green spots on the head and dorsum, a transparent pericardium, and a tonal call that lasts 0.27-0.4 s, with a dominant frequency of 5219.3-5329.6 Hz. Also, a mitochondrial phylogeny for the genus is presented that contains the new species, which is inferred as sister to <i>H. pellucidum</i>. Conservation threats to <i>H. yaku</i><b>sp. n.</b> include habitat destruction and/or pollution mainly because of oil and mining activities.
