A New Species of Narrow-Mouthed Frog of the GenusKaloulafrom Eastern Indochina

Abstract

We describe a new species of frog of the genus Kaloula (family Microhylidae) from Vietnam, Laos, and Cambodia based on morphological evidence. The new species has previously been mistaken with K. baleata, which it most closely resembles. Kaloula indochinensis sp. nov. can be distinguished from its congeners by the following combination of characters: maximum snout–vent length 53.7 mm; finger tips expanded into wide discs; the majority of specimens with two subarticular tubercles on the fourth toe; inner and outer metatarsal tubercle slightly raised, inner metatarsal tubercle shorter than first toe; absence of dorsolateral stripe; and large, bright, orange-yellow axillary and inguinal spots.
