Description

Small newt. Vomerine tooth series in two lines which converge anteriorly and diverge posteriorly. Three longitudinal grooves converge near the nostrils and are well-developed on the upper surface of the head. Tail length approximately equal to body with head. In the aquatic phase, the skin is smooth. In the terrestrial phase, the skin has small granules. Dorsal coloration varies from reddish-orange to dark olive-brown, almost black. Back with a median light stripe. Dorsal and lateral surfaces with dark spots and points. Belly bright orange, without pattern. Male without middorsal crest even during the breeding season. Both sexes have caudal fin folds, but they are better developed in males during the breeding season. Other male external differences include: body shape transversely more square than oval; swollen cloaca with black lips (yellow in female); small filament-like protuberance on the tail tip which remains in the terrestrial phase as a black spike ca. 1 mm length; dark upper caudal fin fold; and white longitudinal band with black points on the lower surface of the tail during the breeding season; background coloration usually darker.
