Feihyla inexpectata
Feihyla inexpectata is a species of frog in the family Rhacophoridae. This recently described species is endemic to Malaysian Borneo and known from its type locality in the Maliau Basin Conservation Area, Sandakan Division, Sabah and from Danum Valley, also in Sabah. Common name Bornean opposite-fingered tree frog has been coined for it.
Etymology
The specific name inexpectata is Latin and refers to the fact that finding a species of the genus Chiromantis, as the species was originally assigned to, was considered unexpected in Borneo given that the genus was previously only known from continental South-East Asia.Description
The type series consists of two adult males and a metamorphosing juvenile. The adult males measured in snout–vent length. The metamorph measured SVL and had a tiny tail stump. Females are unknown.The head is wider than the body. The snout is truncated in the side view and sloping anteroventrally. The canthus rostralis is rounded. The eyes are large and protuberant. The tympanumis distinct and subcircular. The forelimbs are long and relatively robust. The fingers have expanded discs and are less than half-webbed. The hindlimbs are comparatively short. The toes bear expanded discs and are webbed. Skin is smooth except for some minute, blunt asperities in the back. The coloration is changeable, varying between whitish-yellow on body and pinkish on limbs to light brown. There are scattered, small dark-brown spots on the back. A dark lateral band runs from the tip of the snout over upper half of tympanum to about one-half way down the body and is bordered under by a narrower white stripe. The ventrum is semitransparent and immaculate creamy white.
