It likely represents a species complex of at least two species. Description Males measure and females in snout–vent length. Colouration is variable; dorsum is dark reddish to uniform dark brown, sides are black. There is a pale yellowish or creamy white lateral line and cream-coloured dorsolateral line. Iris is dark coppery black. Diet Diet is varied and includes mites, ants, coleopterans, dipterans, homopterans, and colembolas.

It is threatened by habitat loss; while a somewhat adaptable species, it disappears if the habitat becomes too open and dry.
