Diagnosis:

Telmatobius espadai is distinguished from other similar species by a combination of morphological features and colour patterns (De la Riva 2005).

Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over the last ten years, inferred from the apparent disappearance of most of the population, perhaps due to climate change and/or chytridiomycosis.

(1) Snout-vent length of males to 52.8 mm, females to 50.7 mm; (2) head in lateral profile moderately high, with rounded snout; (3) snout slightly subacuminate in dorsal view; (4) lips not flared; (5) postcommisural gland present, large; (6) tympanum barely distinct or not visible; a strong supratympanic fold; (7) forelimb moderately robust, with no humeral spine; (8) nuptial spicules small, not closely arranged; nuptial pad on dorsal surface of thumb and separate from inner palmar tubercle; (9) foot webbing about 1/3 of toe lengths, reaching only their second subarticular tubercle; plantar surface smooth; (10) tarsal fold absent; (11) dorsal skin covered with numerous small, flat pustules; (12) dorsum greenish-brown with small black and yellow flecks; (13) venter uniformly gray, ventral surfaces of limbs orange; (14) iris dark brown.

Type locality:

Telmatobius espadai is known from the vicinity of Choquetanga Chico, Inquisivi Province, Department of La Paz, Bolivia, and from near Río Apaza, Province of Chapare, Department of Cochabamba, Bolivia. It is considered to be endemic and only known to occur in the two places where it was collected, which are ca 12 km (airline) from each other, 3,000-3,500 m asl (De la Riva 2005).

Distribution:

Bolivia

Ecology:

The species can be found in clear streams at the ceja de montaña, the upper limit of the cloud forest. Adult specimens were found both above and under water under trunks and stones, juveniles and tadpoles were found under stones and among aquatic plants in small rivulets and tributary branches of the main stream. Telmatobius espadai may be a moderately terrestrial species (De la Riva 2005). The species inhabits permanent streams (I. De la Riva pers. comm. 2008).
