Yunganastes mercedesae
EOL Text
Yunganastes mercedesae is a species of frog in the Craugastoridae family. It is found in Bolivia and southern Peru. It is sometimes known as Mercedes' robber frog.[2] It is named after Mercedes S. Foster, who collected the holotype and was acknowledged for her herpetological collection efforts in South America.[3]
Description[edit]
Yunganastes mercedesae is a beautiful frog with a striking colour pattern: the dorsum is medium brown with irregular, light green splotches and some black marks, and black eyestripe and lip marks.[3] It is still known from relatively few individuals. Based on three adult males and two adult females, males measure 42–52 mm (1.7–2.0 in) in snout–vent length, whereas females are much larger at 62–63 mm (2.4–2.5 in) SVL.[4]
Habitat[edit]
Yunganastes mercedesae is a rare frog inhabiting Andean cloud forests at moderate elevations (1400-1950 m).[4]

Initially, this species was known only from the type locality, 3.3km north of the road towards San Onofre, in Chapare Province, in Cochabamba Department, but more recently there are more records from La Paz Department, also in Bolivia (Lynch and Duellman 1997; De la Riva et al. 2000; Cortez 2001). It has been recorded from 1,950-2,400m asl.@@

Eleutherodactylus mercedesae is known from two adult males reaching 40.1-49.5 mm SVL. Skin of dorsum is finely granular with ventral skin areolate. Irregular indistinct dorsolateral folds present. Tympanum is prominent and superficial, 33% diameter of eye. Snout is subacuminate in dorsal view and round in lateral profile. Canthus rostralis is sharp. Vomerine processes are large and nearly triangular, just medial and posterior to choanae. Head is equal to or wider than body. Upper eyelids with a few small tubercles. Two low to moderate postrictal tubercles are present posteroventrally to the tympanum. There are also scattered tubercles on the head (three or four on upper eyelid and one between eyes, two preinterocular and one on loreal surface, two behind eyes on a line between tympana). First finger is slightly shorter than second, fingers long with truncate tips and large pads. Lateral fringes on fingers present. Ulnar tubercles absent. Two metatarsal tubercles present, inner is oval and four times the size of the low outer. Toes have narrow lateral fringes with basal webbing. Toe tips truncate with broad pads. In life, its coloration is “medium brown dorsally with irregular, light green splotches (spots look like moss) and a few black marks; black eyestripe (canthal plus supratympanic stripe) and lip marks; limb iridescent coppery with green marks; thighs and sides of body speckled cream, green, and brownish black; ventrally pearl yellow, mottled brown; iris gold” (from field notes of M. S. Foster).
