It is endemic to Ecuador and found on the eastern slopes of the Andes in Pastaza and Morona-Santiago Provinces.[2][3] However, it is suggested that specimens from Pastaza represent a different, possibly undescribed species.[3] DescriptionMales measure {{convert|17.5|-|20|mm|abbr=on}} and females {{convert|21|mm|abbr=on}} 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.[3][4] Male call is unknown.[4] Habitat and conservationIts natural habitats are pluvial premontane and very humid premontane forests. Its altitudinal range is {{convert|970|-|1981|m|abbr=on}} asl. It is threatened by habitat loss and degradation caused by agricultural expansion and logging; introduced species might also be a threat.[1] References1. ^1 {{Cite journal | author = Coloma, L.A. | author2 = Ron, S. | author3 = Grant, T. | author4 = Morales, M. | last-author-amp = yes | title = Hyloxalus exasperatus | journal = The IUCN Red List of Threatened Species | volume = 2004 | page = e.T55077A11236033 | publisher = IUCN | date = 2004 | url = http://www.iucnredlist.org/details/55077/0 | doi = 10.2305/IUCN.UK.2004.RLTS.T55077A11236033.en | access-date = 10 January 2018}} 2. ^{{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Dendrobatidae/Hyloxalinae/Hyloxalus/Hyloxalus-exasperatus |title=Hyloxalus exasperatus (Duellman and Lynch, 1988) |author=Frost, Darrel R. |year=2014 |work=Amphibian Species of the World: an Online Reference.
