Eok Sticky Frog

Kalophrynus eok is only known from the holotype, an adult male measuring 26 mm (1.0 in) in snout–vent length. The snout is obtuse and slightly projects beyond the mandible. The head is broader than it is long. The tympanum is distinct; no supratympanic fold is present. The fingers and the toes have rounded tips and basal webbing. The dorsum is granular, particularly on the eyelids and upper surfaces of the limbs. The dorsal coloration is brick-red. There is a sepia interorbital band that is connected to an irregular, inverted V-shaped scapular mark of the same color, which in turn is followed by an irregular transverse band across the midbody. The venter is flesh color and sides of the throat are peach red.

The holotype was found in primary submontane forest at an elevation of about 1,050 m (3,440 ft) above sea level. The specimen was calling from a water-filled node of a bamboo plant fallen across a forest path. Breeding might take place in water pools at the internodes of such bamboo plants. The Kelabit Highlands in their entirety are threatened by commercial logging. Furthermore, the type of bamboo this species was found in are utilized locally.
