We describe a new species of terrestrial frog of the genus Noblella from the eastern versantsoftheEcuadorianAndesintheupperPastazawatershed.Noblellanaturetrekii sp. n. differs from its Ecuadorian congeners by the presence ...
A new species of terrestrial frog Pristimantis (Strabomantidae) from the upper basin of the Pastaza River, Ecuador

Ron Melo, Santiago Rafael (2019-03-19)

We describe a new species of Pristimantis from the montane forest of the Río Zuñag Ecological Reserve, upper basin of the Pastaza River, Ecuador. Pristimantis mallii sp. n. is characterized by a snout-vent length of 11.6–21.3 ...
A new treefrog from Cordillera del Cóndor with comments on the biogeographic affinity between Cordillera del Cóndor and the Guianan Tepuis (Anura, Hylidae, Hyloscirtus)

Ron Melo, Santiago Rafael (2018-12)

The Hyloscirtus larinopygion group is a clade of 16 species of large hylids that inhabit cascading Andean streams. They have brown coloration that, in most species, contrasts with bright marks. Herein morphological and ...
Advertisement calls and DNA sequences reveal a new species of Scinax (Anura: Hylidae) on the Pacific lowlands of Ecuador

Ron Melo, Santiago Rafael (2018-09)

Scinax is a speciose genus of Neotropical hylid frogs. We describe a new species from western Ecuador (elevations between 0 and 1207 m) using morphology, vocalizations, and DNA sequences. We also present a new phylogeny ...
Bats, trypanosomes, and triatomines in Ecuador: new insights into the diversity, transmission, and origins of Trypanosoma cruzi and chagas disease

Grijalva Cobo, Mario Javier; Ocaña Mayorga, Sofía Beatriz; Pinto Báez, Christian Miguel; Villacis Salazar, Anita Gabriela (14/10/2015)

The generalist parasite Trypanosoma cruzi has two phylogenetic lineages associated almost exclusively with bats—Trypanosoma cruzi Tcbat and the subspecies T. c. marinkellei. We present new information on the genetic ...
Cylindrocarpon-Like (Ascomycota, Hypocreales) Species from the Amazonian Rain Forests in Ecuador: Additions to Campylocarpon and Dactylonectria

Gordillo Artieda, Ana Graciela (2017)

Dactylonectria and Campylocarpon are two related genera of Hypocreales sharing a cylindrocarpon-like asexual morph, mostly known as soil-borne pathogens. During a study of the fungal communities of roots (endophyte) and ...
Description and Phylogeny of a New Species of Andean Lizard (Gymnophthalmidae: Cercosaurinae) from the Huancabamba Depression

Torres Carvajal, Lenin Omar (2020)

Divergence of tropical pitvipers promoted by independent colonization events of dry montane Andean habitats

Torres Carvajal, Lenin Omar (2019)

AIM: A poorly explored feature of the origin and maintenance of Neotropical biodiversity is how the evolutionary dynamics of colonization and differentiation in relation to lowland and highland habitats has impacted lineage ...
Hidden diversity in two widespread snake species (Serpentes: Xenodontini: Erythrolamprus) from South America

Torres Carvajal, Lenin Omar (2020-05)

The spatial distribution of genetic diversity of widely distributed Neotropical tetrapods has been an active research field during the last decade, although it has focused on lowland (mostly Amazonian) taxa. In this paper ...
