Hyloxalus
''Hyloxalus'' is a genus of poison dart frogs, family Dendrobatidae. The genus is distributed in Central and South America, from Panama south to Peru (along the Pacific coast), along with Venezuela, Colombia, and Ecuador. They also inhabit the eastern foothills of the Andes in Bolivia to Venezuela, east to the upper Amazon Basin. Description ''Hyloxalus'' are small to moderate-size frogs, ranging from about in snout–vent length. Most species have cryptic, brown, gray, or black dorsal coloration, but some have conspicuous, bright colors (e.g., '' Hyloxalus azureiventris''). A pale oblique lateral stripe is always present. Toe webbing is absent in most species but is present in some species and can even be extensive. Fingers bear narrow to moderately expanded discs. Reproduction Most species deposits their eggs in terrestrial nests and transport the tadpole A tadpole or polliwog (also spelled pollywog) is the Larva, larval stage in the biological life cycle of an amphibia ...

Hyloxalus Bocagei
''Hyloxalus bocagei'' is a species of frog in the family Dendrobatidae. It is found on the northeastern side of the Andes in Ecuador ( Sucumbíos, Orellana, and Napo Provinces) and in Colombia ( Cordillera Oriental in the Caquetá Department). The specific name ''bocagei'' honors José Vicente Barbosa du Bocage, a Portuguese zoologist. Common name Bocage's rocket frog has been coined for this species. Taxonomy ''Hyloxalus bocagei'' belongs to a group of species that are difficult to identify, and the taxonomic history of the group is complex. '' Hyloxalus maculosus'' has been considered a junior synonym of ''Hyloxalus bocagei'', but is now recognized as a species. '' Hyloxalus italoi'' and '' Hyloxalus yasuni'' were described as new species in 2010. Description Males measure and females in snout–vent length. Dorsum is olive-brown with dark brown dorsal blotches and flanks with a dark brown stripe. There are oblique lateral stripes extending from anterior corner of the eye ...

Hyloxalus Azureiventris
The sky-blue poison frog (''Hyloxalus azureiventris'') is a species of poison dart frog. It is endemic to Peru and known from the lower eastern versant of the Andes in the upper Amazon basin of the San Martín Region. Habitat and ecology The species habitat is primarily lowland tropical rainforests as well as inland wetlands of Peru. The adult frog seems to prefer caves and rock piles, but juvenile frogs have been observed in the leaf litter. Little is known about the species' adaptability to modified habitats. This frog has been observed between 200 and 1200 meters above sea level. This frog's range includes at least one protected park: Cordillera Escalera Regional Conservation Area. Reproduction People hear the male frogs calling to the female frogs at dusk. They perch on rocks or sit in crevices. The female frog lays 12-16 eggs in water in coconut shells, in hollows in the leaf litter, or in water in bromeliad plants. The male frogs guard the eggs during the two weeks ...

Hyloxalus Chlorocraspedus
''Hyloxalus chlorocraspedus'' is a species of frogs in the family Dendrobatidae. It is only known from two locations: its type locality near Porto Walter, Acre state in Brazil, and another locality in the Ucayali Region of Peru. Habitat Scientists observed this frog in primary forest, usually in open places where a treefall had disrupted the canopy Canopy may refer to: Plants * Canopy (biology), aboveground portion of plant community or crop (including forests) * Canopy (grape), aboveground portion of grapes Religion and ceremonies * Baldachin or canopy of state, typically placed over an a .... Reproduction Scientists infer that the female frog lays eggs on the ground like its congeners, but they have not directly observed female ''Hyloxalus chlorocraspedus'' do so. After the eggs hatch, the adult frog carries the tadpoles to water, for example water in the trunk of a dead tree. Scientists did observe a male frog with tadpoles on his back.

Hyloxalus Exasperatus
''Hyloxalus exasperatus'' or the Yapitya rocket frog is a species of frog in the family Dendrobatidae. It is endemic to Ecuador and found on the eastern slopes of the Andes in Pastaza and Morona-Santiago Provinces. However, it is suggested that specimens from Pastaza represent a different, possibly undescribed species. Description Males measure and females in snout–vent length (based on only six and two specimens, respectively). Toe webbing is absent but it has a dorsolateral stripe and a short oblique lateral stripe. It is similar to '' Hyloxalus whymperi'' but lacks heavy darkening on the abdomen of males. Male call is unknown. Etymology Students of South American frogs named this frog ''exasperatus'' for feelings of frustration and exasperation while waiting fifteen years for scientist Stephen R. Edwards to finish writing his reassessment of the genus ''Colostethus''. Habitat Its natural habitats are pluvial premontane and very humid premontane forests. Its altitudinal ...

Hyloxalus Elachyhistus
''Hyloxalus elachyhistus'' is a species of frog in the family Dendrobatidae. It is found in southern Ecuador (both versants of the Andes) and northern Peru, in the Huancabamba Depression and south to Cajabamba Province. Description ''Hyloxalus elachyhistus'' shows considerable intraspecies variability, and it might represent more than one species. Ecuadorian males measure and females in snout–vent length. Peruvian specimens are smaller: males measure and females SVL. Dorsum varies in colour between populations, from pale olive to brown. There is a pale yellow to tan oblique lateral stripe, usually narrowly bordered by dark brown or black. Reproduction Males may protect the egg clutch. Both males and females may transport the tadpoles. Back-riding tadpoles vary in size, from about in total length. Largest free-swimming tadpoles are in total length. Habitat and conservation The IUCN classifies this frog as least concern of extinction, but the government of Peru classifi ...
