Comprehensive DescriptionRead full entry
Philoria richmondensis is a small frog (adults reach 28 mm in SVL), but with a stout, pear-shaped body. The dorsum and venter are smooth. The head is shorter than wide, with a blunt snout and relatively lateral nostrils. The canthus rostralis is well-defined and concave. Tympana are small and indistinct. The eyes are relatively large and have blue sclera and horizontal pupils. Vomerine teeth are arranged in two lateral plates separated at the midline, behind the level of the choanae. The tongue is rectangular. There is no webbing found on fingers or toes, and digits are long and cylindrical. Finger lengths are, in decreasing order of length, 3>2>4>1. Toe lengths are 4>3>5>2>1. Both inner and outer palmar tubercles are small but distinct. A small, distinct inner metatarsal tubercle is present, but no outer metarsal tubercle. Males have a weakly developed nuptial pad on each thumb. Females have spatulae-shaped first and second fingers. The dorsal color varies from bronze to orange, with zero to many dark speckles. Philoria richmondensis lacks the crescent-shaped black region on the flank that is characteristic of P. pughi. Instead, P. richmondensis has black patches on the lower dorsum, which may sometimes join to form an arrow shape over the middle of the back, and may have black patches on the posterior half of the flank. A black stripe runs posteriorly from the snout through the eye, curving down to reach the base of the forearm. The upper surfaces of the limbs are bronze. Occasionally faint black bands are present on the arms.
This species was named for the Richmond Range area, in which it is found.
