DEFINITION.— Small, adult males 22–27 mm SVL (n = 2); head modest length 26 % HeadL/ SVL; head wider than long NA % HeadW/HeadL; snout moderately broad NA % SnW/HeadL; naris closer to snout than to eye NA % NarEye/SnEye; eye moderately large NA % EyeD/HeadL; tympanum visible but obscured by skin and smaller than eye 50 % Tymp/EyeD; moderate length forelimb NA % Forarm/ SVL and forearm equal crus length NA % Forarm/CrusL; hindlimb moderately long 137 % HndlL/ SVL, NA % CrusL/ SVL, and NA % CrusL/ThghL; hindfoot well developed NA % HndfL/CrusL.

Vomerine teeth presence or absence not reported; palatal fold morphology not reported; tongue shape and size not reported.

Fingers without web; lengths 3>2≈1>4; tips rounded and not dilated; subarticular tubercles prominent, number of tubercle on each finger not reported; fleshy palmar tubercle. No asperities on dorsum of fingers. Toes lightly webbed to below level of proximal subarticular tubercles of toe 4, lengths 4>3≈5>2>1; tips rounded, not dilated; subarticular tubercles prominent and four on 4, not reported for toes 1, 2, 3,5; rounded inner metatarsal tubercle and no outer one.

Dorsum reddish brown, back with or without small black spots; side of head, neck and trunk dark brown; venter pale yellowish white, chin and anterior throat with dark band, scattered black spots posteriorly.

DISTRIBUTION.— Borneo (Kalimatan and Sarawak). See comment below.

NATURAL HISTORY.— Not reported.

COMMENTS.— Preceding information extracted from Peters (1871) and predominantly from Inger (1966). Peters’ description is brief and incomplete for diagnostic purposes. Inger’s account is detailed and includes a second adult male that he discovered in the Rijksmuseum in Leiden. The latter specimen also had specific locality information, “Semedum,” which the holotype did not.

In a 1894 report on a small herpetological collection from one of the Mentawei Islands. Boulenger identified a juvenile specimen (23 mm SVL) and declared that it closely matched Peters’ description of K. punctatus . I believe this identification is erroneous and highly unlikely for a Borneo frog to occur in the distant Mentawei Islands.
