Montane night frog
Astylosternus montanus, also known as the mountain night frog or montane night frog, is a species of frog in the family Arthroleptidae. It is found in the mountains of western Cameroon and into the Obudu Plateau in adjacent south-eastern Nigeria.
Astylosternus montanus has a short, stocky body. Males grow to 44 mm (1.7 in) and females to 52 mm (2.0 in) in snout–vent length. The head is slightly longer than it is wide. The legs are strong and relatively short. The dorsum is granular posteriorly and has few to many short dorsolateral ridges. The dorsum varies in colouration: beige, yellow, grey, or chocolate brown, and bears many distinctly delimited black blotches. The ventral parts are dull yellow with darker patterning. Males have a large black nuptial pad on the thumb and dense spines in the throat.
The male advertisement call is a brief and strong "dlouk", "hou", or "rrra".
