Distribution and habitat
Platymantis diesmosi has only been found on Malinao Volcano in the Bicol Region of the Phillipines at between 900 and 1,160 metres (3,000 and 3,810 feet) above mean sea level, where it is very commonly found. The International Union for Conservation of Nature have classed the species as Data Deficient because it was described recently and not much data has been collected. It has been found at between 30 and 40 metres (98 and 130 ft) away from water and it has been found on cliff edges.
The female specimens of Platymantis diesmosi are the largest with a snout-vent length of 49.8 to 52.7 millimetres (1.96 to 2.07 inches), and the males have a snout-vent length of 28.3 to 39.1 millimetres (1.11 to 1.54 inches). The tip of the snout extends just over the lower jaw and is pointed bluntly. The arms of Platymantis diesmosi are slender and the fingers are long. The lips of the species are swollen. The pupil of the eye is elliptical — horizontally. Platymantis diesmosi is mainly dark brown in colour and has irregular darker markings and/or minuscule white patches. Specimens are sometimes almost totally black and brown with golden highlights. Golden patches can be found of the head and the limbs of Platymantis diesmosi are mainly golden-brown. The fingers are black with brown-gold spots. Platymantis diesmosi has a throat colour of anything between cream and dark brown, and the chest and stomach are between dark brown with white patches to a cream colour.
