Atelopus ignescens, the Jambato toad or Quito stubfoot toad or Jambato harlequin frog,

endemic to the northern Andes of Ecuador.[1][3][4] This once abundant species was believed to be extinct until its rediscovery in 2016.[1][5][6][7] The specific name ignescens means "to catch fire," presumably in reference to the orange ventral color of this species.[8]

Taxonomy

A closely related, perhaps undescribed species might exist in Colombia.

Atelopus carrikeri).[10] Later studies have indicated that its closest relative is an undescribed species from central Ecuador (Bolívar and Chimborazo Provinces).[4]

Description

Original drawing by Albert Charles Lewis Günther in 1858

Males measure on 34–41 mm (1.3–1.6 in) and females 36–48 mm (1.4–1.9 in) in snout–vent length. The body is robust with long limbs and truncate snout. The dorsal coloration is uniformly black, as is the iris. The ventral side is orange-red; the belly is lighter in color, suffused with yellow.[8]

Conservation

With the last recorded sighting dating to 1988, the species was thought to be extinct until early 2016, when a relict population was discovered in an undisclosed location.[5]

Atelopus ignescens was formerly abundant along streams, rivers and ponds of the

IUCN. Other threats include habitat destruction, pollution, climate change, and invasive rainbow trout.[1][5]
