Description

The Bainskloof moss frog is a small frog which reaches a maximum length of 22 mm. The body is rather squat with short limbs and a rounded head. The background colour of its skin varies from orangey brown to black with darker patches and paler spots on the back and legs.[4]

Distribution

The Bainskloof moss frog is endemic to Riviersonderend Mountains, Dutoitsberg, Elandskloof and Limietberg Mountains in Western Cape Province, South Africa. This species can be found between 300-2,000 m above sea level. The extent of this species total distribution is probably less than 20,000 km².[1]

Habitat

The Bainskloof moss frog favours wet mossy areas near watercourses, hillside or roadside seepages, and heavily vegetated streams, within montane fynbos and frequently on steep hillsides. Its known range is situated outside the 750mm isohyet.[1][4]

Biology

The Bainskloof moss frog begins breeding at the onset of the winter rains[5] and the females lay small clutches of 8–10 eggs among moss or similar vegetation in seepages. The male frogs apparently guard the eggs as they call from the laying sites. The eggs hatch into fully formed tiny, 4mm, long froglets rather than tadpoles.[4] It mainly feeds on small invertebrates.[5]

Conservation status

This species is patchily distributed but widespread, in small discrete populations within the montane fynbos which is not a significantly fragmented habitat. The habitat of the Bainskloof Moss Frog lies mainly within protected areas, although even here it is threatened by the spread of pines and other alien species and too frequent bush fires.[1]

Taxonomy

It was formerly considered conspecific with Arthroleptella lightfooti.[2]

gollark: Wow, our predictions of spontaneous contrahumoroform production were completely correct.
gollark: Troubling.
gollark: Wait, are the bees antimemetic? I'll turn on my laptop's antiantimemetics.
gollark: That picture is wrong as it has 0 (zero) visible bees.
gollark: Ugh, you have SO much capacitance.
