Atelopus ignescens has uniformly black coloration on its back and flanks, with small round warts covering most of the back. The venter is wrinkled and is bright orange to red in life, becoming darker in the gular region and lighter on the belly. The ventral surfaces of the limbs are black, except for the forelimbs, which are orange-red underneath. The iris is black. In preservative, the bright underside turns to a cream color with some poorly defined black markings (Coloma et al. 2000).

The species has only been found in the humid forests of Imbabura, Pichincha, Cotopaxi, Napo, Chimborazo, and Bolívar provinces in the northern Andes of Ecuador between elevations of 2800-4200 meters. Habitat includes inter-Andean valleys and sub-paramo and paramo habitats between the western and eastern cordilleras of the Andes (Coloma et al. 2000). Atelopus ignescens was previously abundant and widely distributed across its range. Studies in the 1960s, 1970s, and early 1980s found large numbers of specimens, while anecdotal evidence from as far back as 1864 also suggests great abundance. Survey evidence suggests that the species was still abundant in some localities between 1984 and 1986, but populations apparently rapidly dropped off around that time. Despite extensive searching, none have been found in the wild since 1988, so the species was believed to be extinct (Ron et al. 2003).

It is not known what caused the extinction of A. ignescens. The most likely cause is an outbreak of the fungal disease chytridiomycosis, which has been responsible for amphibian population declines in various parts of the world (Ron et al. 2003), and particularly among high-elevation populations of Atelopus species (La Marca et al. 2005). The first case of chytridiomycosis in Ecuador was discovered in 1980, just a few years before A. ignescens began to decline. Habitat degradation may have contributed, as 27.1% of the paramo and 33.3% of Andean forests have been cleared in Ecuador (Ron et al. 2003). However, this species is able to withstand some degree of habitat degradation. In addition, there is little evidence of human interference in two protected areas where the species was previously found but now is not. Thus habitat degradation is probably not the main cause of this extinction (Ron et al. 2003). Another possible cause is the presence of introduced predatory fishes, as two exotic species of salmonids have been found in streams and lakes of Ecuador’s highlands. However, this idea is not corroborated by evidence of predation. In addition, salmonids have been found within the range of A. ignescens since the 1950s, long before the toads’ decline. Furthermore, the salmonids are not found throughout the entire range of A. ignescens (Ron et al. 2003). Another possible factor may be the dramatic increase in mean annual temperature in Ecuador in recent years. Of ninety years of climatic data analyzed in a study by Ron et al., the year 1987 saw the most extreme combination of warm and dry conditions. These conditions may have increased adult toad mortality, reduced reproductive success, or made the toad more vulnerable to attack by weakening immune function (Ron et al. 2003).

DESCRIPTION.—Snout from above not prominent or projecting, gently rounded, with little or no difference in angle between tip of snout and eye; snout, canthus, and upper eyelid heavily fleshy and raised, with a glandular, fleshy ridge from posterior corner of eye to corner of head. Dorsum of head between fleshy areas flat, smooth, or very finely wrinkled. Snout from side only slightly protrusive beyond lip and lower jaw, nostril lateral and below fleshy area of canthus. Loreal region vertical or slightly concave; eye overhung by heavily fleshy upper eyelid, upper lip not fleshy. Temporal area studded with pointed tubercles in females, or with fleshy, glandular bumps in males. Middorsum of body completely free of warts, glands, pustules; either smooth or finely wrinkled. Dorsolateral area and sides of body in females heavily studded with rounded glands that have one to several raised, pointed spicules on them, giving spiny appearance; same area in males covered with low, rounded glandular areas without spicules. Chin and belly finely wrinkled and occasionally lightly shagreened on chest in males, same in females, but with tendency in some individuals to have darkened spiny area across chest.
Forelimb short, stubby, and fleshy; humeral region heavily studded with spicules in females, covered by small rounded glands in males; forearm in both sexes heavily fleshy but quite smooth, contrasting strongly with upper arm. When forelimb is pulled back along body, tips of digits do not reach past hind leg in males or past groin in females. Entire forefoot fleshy, all digits free and prominent, with fleshy webbing only at base. Sole of foot covered with pustules, subarticular tubercles not differentiated from these pustules, palmar tubercle larger and clearly defined. Males have horny excrescences on both first and second digits; first digit usually strongly bent under and flexed, with prominent thick, rounded, fleshy hump dorsally, keratinized area extends from tip of digit to base; second digit with cornified area only at base.
Hind limb short, stout, fleshy; femoral region studded with spines in females, heavily pustulate in males, crural area smooth and fleshy. Tibiotarsal articulation reaches to level of arm insertion when carried forward along body; heels are well separated when tibiofibulae are parallel to femora at right angles to body.

Subarticular tubercles not clearly distinguishable from pustules, outer metatarsal tubercle small but raised and prominent, inner metatarsal tubercle larger but not as raised.
COLOR IN ALCOHOL.—Dorsum of head, body, and limbs uniform black, extending down sides and ending abruptly at edge of belly, which is yellow to yellowish white. Some individuals have spotting on chest. Ventral surfaces below anus and on limbs often light brown to black; pigment distribution ventrally differs considerably from one individual to the next. Lower lip usually dark, same color as upper lip, and sharply distinct from rest of chin.
COLOR IN LIFE (from a series of 25 individuals collected near Quito June 6, 1959).—Dorsum dark brown to black, lightening slightly on dorsum of limbs. Dorsal color sharply set off from ventral color along a line running from corner of mouth along the lateroventral line. Ventral surfaces highly variable, from a light cream unicolor to light cream with yellowish or orange border to unicolor yellowish to unicolor orange. The eye is a deep black, no pupil color can be distinguished. Often with a bright orange or yellow spot on ventral side of crus, and some have same on dorsum of foot. In this same series of 25, the following variation in color of the ventral surfaces was noted (individuals can occur in more than one tabulation): venter mostly dull orange–5; cream with orange in axilla and inguinal region–4; yellowish, with brightest yellow in limb insertions–2; yellow spot on dorsum of foot–6; yellow spot on ventral surface of crus–8; yellow venter with reddish orange in limb insertions–2; unicolor yellow–2; venter of limbs maculated with bright orange–1. A series from 5 kilometers west of Papallacta all had bright, tomato-red bellies in life but of course, now are identical with other alcoholics in belly color.

fornecido por wikipedia EN
Atelopus ignescens, the Jambato toad or Quito stubfoot toad or Jambato harlequin frog,[2] is a species of toad in the family Bufonidae. It is 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.[3][9] Alexander G. Ruthven believed Atelopus ignescens to be the closest relative of the Guajira stubfoot toad (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 páramo surrounding the Ecuadorian capital city of Quito. The species started to decline in the 1980s, probably due to the chytridiomycosis that ravaged other amphibian species around the world, and prior to its rediscovery had been listed as extinct by the IUCN. Other threats include habitat destruction, pollution, climate change, and invasive rainbow trout.[1][5]

El jambato negro (Atelopus ignescens) es una especie de rana nativa de Ecuador que se consideraba extinta, pues dejó de observarse desde 1988,[1] hasta 2016.[2]
Descripción
En promedio, el macho mide 37,8 mm de longitud rostro-cloacal y la hembra 42,5 mm.[3] El dorso y los flancos son de color negro azabache, con pequeñas verrugas redondas. El vientre es arrugado y de color naranja brillante a rojo vivo, más oscuro en la región gular y más claro en el bajo vientre. Las superficies ventrales de las extremidades son de color negro, a excepción de las extremidades anteriores por debajo, que son de color rojo a anaranjado. El iris es negro.[4]
Hábitat
Esta especie nativa de los bosques húmedos de montaña y páramos, entre los 2.800 y 4.200 m de altitud,[1] es capaz de sobrevivir en hábitats modificados por el hombre, habiendo llegado a encontrarse incluso en zonas urbanas periféricas de Quito, Ambato y Latacunga. Su distribución abarcaba desde la provincia de Imbabura al norte hasta las provincias de Chimborazo y Bolívar al sur.[3]
Redescubrimiento
En mayo de 2016, científicos del Centro Jambatu de la Fundación Otonga e IKIAM anunciaron haber comprobado el reencuentro de esta especie.[2] El jambato negro fue observado primero por un sacerdote salesiano y una familia campesina. Posteriormente los expertos Luis Coloma, Giovanni Onore y Elicio Tapia certificaron el hallazgo.[2]
El proceso de extinción de esta especie se relaciona a múltiples factores, siendo algunos de ellos el cambio del clima, la aparición en esta especie de la enfermedad quitridiomicosis, la pérdida de hábitat y la introducción de depredadores foráneos.[1][2]

Atelopus ignescens, connu comme jambato negro en Équateur, est une espèce d'amphibiens de la famille des Bufonidae. Considérée comme éteinte depuis 1988[1], notamment à cause de la maladie mortelle provoquée par un champignon parasite, elle fait partie de quatre espèces d'amphibiens redécouvertes récemment en Équateur et en Colombie[2].
Description
En moyenne, le mâle mesure 37,8 mm de longueur rostro-cloacale et la femelle 42,5 mm.[3] Le dos et les flancs sont noirs de jais, avec de petites verrues arrondies. Le ventre est ridé et de couleur orange vif à rouge vif, plus foncé dans la région gulaire et plus clair sur le bas-ventre. Les surfaces ventrales des membres sont noires, à l'exception des membres antérieurs inférieurs, qui sont rouges à orange. L'iris est noir.[4]
Habitat
Cette espèce est endémique d'Équateur[5]. Elle se rencontrait autrefois fréquemment dans les forêts humides montagnardes et les paramos, entre 2 800 et 4 200 m d'altitude, de la province d'Imbabura à celles de Chimborazo et de Bolívar.
Elle est capable de survivre dans des habitats modifiés par l'homme, ayant même été rencontrée dans les franges urbaines de Quito, Ambato et Latacunga. Son aire de répartition s'étend de la province d'Imbabura au nord aux provinces de Chimborazo et de Bolívar au sud[3].
Redécouverte
Le processus d'extinction de cette espèce, qui était actée depuis 1988, est lié à de multiples facteurs, parmi lesquels le changement climatique, les ravages de la chytridiomycose des amphibiens due au champignon aquatique chytride (Batrachochytrium dendrobatidis), la perte de leur habitat et l'introduction de prédateurs étrangers[1],[6].
Or, en mai 2016, les scientifiques du Centre Jambatu de la Fondation Otonga et de l'Ikiam annoncent avoir validé la redécouverte de cette espèce. Le jambato noir a été observé pour la première fois par un prêtre salésien et une famille de paysans. Les experts Luis Coloma, Giovanni Onore et Elicio Tapia ont ensuite certifié le constat.[6]

Herpetologie Atelopus ignescens is een kikker uit de familie padden (Bufonidae) en het geslacht klompvoetkikkers (Atelopus). De soort komt endemisch voor in Ecuador. Atelopus ignescens werd voor het eerst wetenschappelijk beschreven door Emilio Cornalia in 1849.[2]
Verspreiding
Voorheen was Atelopus ignescens erg algemeen in de hooglanden van de noordelijke Andes in Ecuador. Bergbossen en páramo van 2.800 tot 4.200 meter boven zeeniveau vormen het leefgebied. Het verspreidingsgebied liep van de provincie Imbabura tot aan de provincies Chimborazo en Bolívar. Vermeende waarnemingen uit zuidelijk Colombia bleken onjuist. Aan het einde van de jaren tachtig namen de aantallen van Atelopus ignescens fors af en lange tijd dateerde de laatste waarneming uit 1988, toen bij Cayambe een exemplaar werd gezien. Chytridiomycose en klimaatsveranderingen werden geduid als vermoedelijke oorzaken van het verdwijnen. Door de internationale natuurbeschermingsorganisatie IUCN werd de soort als uitgestorven beschouwd. In 2016 werd een nieuwe waarneming van Atelopus ignescens bekend gemaakt.[3] De locatie werd geheim gehouden. In de zoektocht naar nog levende exemplaren van de soort, had het Centro Jambatu een beloning van duizend Amerikaanse dollar uitgeloofd. De tienjarige David Jalaica vond samen met zijn broer in april 2016 een populatie in een alfalfaveld. Door het Centro Jambatu werden 54 individuen en een groot aantal kikkervisjes gevangen voor de opzet van een kweekprogramma.[4]
Uiterlijke kenmerken
Atelopus ignescens heeft een zwarte kleur met een oranjerode buik. De soortnaam, die "vlambaar" betekent, verwijst naar de kleur van de buik.
Leefwijze
Atelopus ignescens leeft op de grond en plant zich voor in stroompjes.
