Description edit

Hyloxalus cevallosi is a small ground-dwelling species of frog that is easily overlooked. It is characterized by slanting lateral, ventrolateral, and relatively incomplete dorsolateral stripes, a large tympanum, almost non-fringed toes with no webbing, and a broad abdomen.[2] One male measured 18 mm (0.71 in) and two females 21 mm (0.83 in) in snout–vent length.[4]

Distribution edit

Hyloxalus cevallosi is native to the Pastaza Province in central Ecuador where it is present on the eastern side of the Andes between 480 and 970 m (1,575 and 3,182 ft) above sea level. it has been recorded from only three localities in the Pastaza Province. Records from elsewhere may refer to this species or Leucostethus fugax and require confirmation.[1]

Status edit

Hyloxalus cevallosi is currently listed as "Endangered" by the IUCN on the IUCN Red List of Threatened Species and its population is decreasing.[1] Members of the species live in three localities in a total space less than 500 square kilometers. It is threatened by habitat loss as the forests of the Amazonian foothills of the Andes are slowly disappearing due to agricultural development and logging. It is not known to live in any protected areas.[1]
