“…As more remote, unexplored areas are surveyed, more species are discovered, as the results of recent studies in Ecuador (e.g. [19, 20]), Peru [21, 22, 11] and Brazil [23, 14] have demonstrated. It is expected that Colombia will follow the same pattern of hidden diversity.…”

Ikakogi is a behaviorally and morphologically intriguing genus of glassfrog. Using tadpole morphology, vocalizations, and DNA, a new species is described from the Sierra Nevada de Santa Marta (SNSM), an isolated mountain range in northern Colombia. The new taxon is the second known species of the genus Ikakogi and is morphologically identical to I . tayrona (except for some larval characters) but differs by its genetic distance (14.8% in mitochondrial encoded cytochrome b MT-CYB ; ca. 371 bp) and by the dominant frequency of its advertisement call (2928–3273 Hz in contrast to 2650–2870 Hz in I . tayrona ). They also differ in the number of lateral buccal floor papillae, and the position of the buccal roof arena papillae. Additionally, the new species is differentiated from all other species of Centrolenidae by the following traits: tympanum visible, vomerine teeth absent, humeral spines present in adult males, bones in life white with pale green in epiphyses, minute punctuations present on green skin dorsum, and flanks with lateral row of small, enameled dots that extend from below eye to just posterior to arm insertion. We describe the external and internal larval morphology of the new species and we redescribe the larval morphology of Ikakogi tayrona on the basis of field collected specimens representing several stages of development from early to late metamorphosis. We discuss the relevance of larval morphology for the taxonomy and systematics of Ikakogi and other centrolenid genera. Finally, we document intraspecific larval variation in meristic characters and ontogenetic changes in eye size, coloration, and labial tooth-rows formulas, and compare tadpoles of related species. Ikakogi tayrona has been proposed as the sister taxon of all other Centrolenidae; our observations and new species description offers insights about the ancestral character-states of adults, egg clutches, and larval features in this lineage of frogs.

“…While H. yaku occurs in the Lowland Amazonian forests of Ecuador below 400 m, H. anachoretus is only known from Cloud forests at Abra Patricia, northeastern Peru at 2001 m ( Twomey et al 2014 ), and H. pellucidum inhabits the Foothill, Low Montane, and Cloud forests on the eastern versant of Cordillera Oriental of the Andes of Ecuador and Peru, above 1300 m in northeastern Ecuador and above 1000 m in southeastern Ecuador and eastern Peru (although there are two localities down to 500 m in the Tarapoto area, northeastern Peru) and up to 1740 m ( Lynch and Duellman 1973 ; Duellman and Schulte 1993 ; Cisneros-Heredia and McDiarmid 2006a , b , 2007 ; Castroviejo-Fisher et al 2009 ; Twomey et al 2014 ; cited as Hyalinobatrachium sp. from the Chinchipe River, SW Cordillera del Condor by Cisneros-Heredia et al 2008 ). Hyalinobatrachium yaku is sympatric with H. munozorum and H. ruedai , but they are distinguished by characters that are fairly evident even in preserved specimens (pericardium coloration, dorsal melanophores pattern and snout form; see Diagnosis).…”

Hyalinobatrachium 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, Hyalinobatrachium yaku sp. n., 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 H. pellucidum. Conservation threats to H. yaku sp. n. include habitat destruction and/or pollution mainly because of oil and mining activities.

“…Centrolene durrellorum (Fig. 1) es una especie descrita hace poco y solo conocida de dos localidades en las provincias de Zamora-Chinchipe y Napo entre 800 y 1150 m [9]. Nosotros examinamos 11 especímenes provenientes de cuatro nuevas localidades en dos provincias (ver Apéndice 1): Provincia de Napo: Pungarayacu (DHMECN 03476), Reserva Yachana (DHMECN 03492, 06790-91); Provincia de Sucumbíos: Shushufindi (DH-MECN 06793), Shuara (DHMECN 06794-95).…”

“…Desde el año 2004 se han publicado cerca de cuatro artículos por año relacionados con la diversidad de ranas de cristal (Centrolenidae) del Ecuador [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25]. Gran parte del incremento al conocimiento de este grupo se debe al proyecto "Ranas de Cristal" mentalizado y dirigido por Diego F. Cisneros-Heredia (entrar a centrolenidae.cisneros-heredia.org, para más información), del que participamos algunos de los autores de este artículo.…”

Presentamos nueva información que extiende la distribución latitudinal y altitudinal de cinco especies de ranas de cristal recientemente descritas y poco conocidas de la región oriental de Ecuador. Incluimos datos novedosos sobre su tamaño corporal e historia natural. Se discute información sobre la diversidad y biogeografía de ranas centrolenidas del oriente de Ecuador, encontrando que se encuentran asociadas con seis formaciones vegetales comprendidas entre las estribaciones orientales y la baja Amazonia. Identificamos tres importantes zonas de diversidad y endemismo en la región oriental de Ecuador asociadas con las cuencas hidrográficas de los ríos Napo, Pastaza y Santiago. Los ecosistemas de bosques Montano Bajos y Piemontanos concentran la mayor diversidad y endemismo para ranas centrolenidas, sin embargo 77% de ellas están amenazadas. Es trascendental juntar todos los esfuerzos posibles para investigar y conservar este substancial grupo de la fauna ecuatoriana.
