Description

provided by AmphibiaWeb articles
Ansonia endauensis is a small and slender toad. Males reach at least 17.4 mm in SVL, and females at least 28.5 mm in SVL. The head is the same width as the body. Both body and head are somewhat flattened. When viewed from above, the snout is square and projects past the lower jaw. The tip of the snout has a vertical ridge and is laterally constricted. There is no yellow wart at the angle of the jaw, unlike Ansonia malayana. Eyes are large. The tympana are distinct and vertically elliptical. Canthi are sharp and weakly constricted, and the lores are vertical. Neither cranial crests nor parotoids are present. The fingers are long and slender and unwebbed, with narrow, rounded tips. The first finger is shorter than the second finger. Toes are webbed with each toe having one or more phalanges projecting past the webbing; the third and fifth toes each have two phalanges free of the webbing. Both inner and outer metatarsal tubercles are present. There is neither a tarsal ridge nor an interorbital ridge. Dorsally and laterally, the skin is tubercular, with small, rounded tubercles bearing a brown tip. The tubercles are not regularly arranged, with the exception of a single row of small spinose tubercles underneath the mandibles, and three rows of tubercles in the mental region. The abdominal skin is coarsely granular. The dorsum is black and the ventrum is gray. This species has an orange spot below the eye, as well as orange spots on the side of the head and neck, and small orange spots on the flanks. Prominent orange bars are found on the upper and lower parts of the limbs. Light spotting is present on the belly as well as the underside of the hindlimbs, but there is no spotting in the gular region or on the underside of the forelimbs. A. endauensis can be distinguished from all other species of Ansonia by dual vocal slits in the male (other Ansonia have only one vocal slit, on either the right or the left), and red irises (other Ansonia have golden-brown irises).

Distribution and Habitat

provided by AmphibiaWeb articles
Ansonia endauensis occurs in southern peninsular Malaysia. The initial species description is from the Endau-Rompin National Park. Since this species has only recently been described (Grismer 2006), the full extent of its distribution is not yet known. It appears to prefer rocky streams in closed-canopy lowland forest. The holotype was collected at 46 m in elevation.

Ansonia endauensis

provided by wikipedia EN

Ansonia endauensis is a species of toads in the family Bufonidae. It is endemic to the Malay Peninsula and only known from the Endau-Rompin National Park in southern Peninsular Malaysia.[1][3][4][5]

Description

The distinguishing features of the species include unique red eye color, dual vocal slits in males, and a unique combination of head, body, digit, and color pattern characteristics.[4] Males grow to at least 17.4 mm (0.69 in) and females to 28.5 mm (1.12 in) in snout–vent length. The habitus is slender. The dorsum is almost uniformly black, with orange spots on the flanks, the sides of neck and head, as well as below the eye.[2]

Habitat and conservation

The species inhabits closed-canopy lowland forest. All individuals were collected from a small, rocky stream 46 m (151 ft) above sea level , where they were found in vegetation overhanging the stream bed, less than one metre above the ground.[1][2][4]

The known population lives within a well-protected reserve. Habitat loss caused by logging and agricultural expansion is a probably threat outside the reserve.[1]
