Yunganastes bisignatus
Yunganastes bisignatus is a rainfrog in the family Craugastoridae (order Anura), recorded as Endangered and tied to Bolivia.
Appearance
Adult males measure 28–35 mm (1.1–1.4 in) and adult females, based on a single specimen, 47 mm (1.9 in) in snout–vent length. The dorsum is dark reddish-brown. The flanks are lighter with cream ground color. There are various dark brown markings, among them a narrow dark brown band running from the tip of snout to the eye along canthus.
Range and habitat
It is endemic to the La Paz Department, Bolivia, and known from between the Inquisivi and Nor Yungas Provinces.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Direct-developing rainfrogs live in wet forest. They do not need a pond, which is why a logged hillside can erase a species.
Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.
In crisis
Yunganastes bisignatus is abundant at its type locality but its range is small and it is threatened by habitat loss.
Direct-developing frogs vanish with the forest floor. There is no pond population waiting off-site.
