ETYMOLOGY.— The name barioensis derives from the town of Bario in the Kelabit Highlands of Sarawak.

DISTRIBUTION.— Sarawak, Borneo. Presently, K. barioensis is known only from the vicinity of the type locality .

NATURAL HISTORY.— These frogs are ground-dwelling residents of broad-leaf and bamboo forest. All specimens were collected in mid August from the leaf litter along forest trails. Males, hidden beneath the leaf litter, were calling in scattered small chorus and chorused in late afternoon and early evening whether it rained or not.

COMMENTS.— The extreme variance of the Tymp/EyeD data suggest an error in the measurement of one individual.
