Description

provided by AmphibiaWeb articles
In this small species of Allobates males attain a snout-vent length of 16.9 mm and females reach 18.4 mm. The discs on the fingers and toes are expanded, half again the width of the penultimate phalanges. Finger I longer is than Finger II, and Finger III is swollen in males. Lateral fringes are absent on the fingers and toes. Inner and outer tarsal folds are absent, but an outer tarsal tubercle is present. Basal webbing is present between Toes II and IV; elsewhere webbing is absent. The dorsum is tan with brown markings usually consisting of an interorbital bar and an X-shaped mark in the scapular region; the posterior parts of the X-shaped mark may be connected to a roughly triangular mark in sacral region. The dorsolateral stripes are pale yellow, narrow on the head and diffuse on the body. A broad, dark brown stripe across tip of snout passes through the loreal and tympanic regions, becomes broader on the flanks, and extends to the groin; it is bordered below on the flanks by a narrow pale yellow ventrolateral stripe. The flanks below the ventrolateral stripes are creamy tan with brown flecks. Oblique lateral stripes are absent. The dorsal surfaces of the hind limbs are grayish brown with many small dark brown flecks and one broad transverse brown bar on each thigh, shank, and foot; the posterior surfaces of the thighs are brown. The labial region is creamy white with brown flecks; the throat and belly are pale lemon yellow, and the ventral surfaces of limbs are flesh colored. The digital scutes are pale gray, in contrast to the adjacent dark brown surfaces; the iris is greenish bronze. A median lingual process is absent; the color of the testes is unknown.

Allobates ornatus

provided by wikipedia EN

Allobates ornatus is a species of frog in the family Aromobatidae. It is endemic to northern Peru where it is only known from near its type locality, Tarapoto in the San Martín Province, on the eastern slopes of the Cordillera Oriental.[1][2]

Description

Males grow to 17 mm (0.7 in) and females to 18 mm (0.7 in) in snout–vent length. The body is slender. The head is longer than it is wide. The snout is long and broadly truncate in dorsal view but rounded in lateral view. The tympanum is distinct and only barely obscured by the diffuse supratympanic fold above. The fingers and toes have expanded terminal discs. The fingers lack webbing, whereas the toes have basal webbing. Skin is smooth. The dorsum is tan with brown markings, including an interorbital bar, an X-shaped mark in the scapular region, and a triangular mark in the sacral region. A dark brown stripe starts from the tip of the snout and continues along the flanks as a broad stripe, bordered by pale yellow dorsolateral and ventrolateral stripes. The throat and belly are pale lemon yellow. The iris is greenish bronze.[3]

Reproduction

In most Allobates, the eggs are deposited in leaf litter; after hatching, the parents transport the tadpoles on their backs to small pools. However, at least two species, Allobates nidicola and Allobates chalcopis, have endotrophic tadpoles that develop into froglets terrestrially.[4] The presence of very large eggs in a female Allobates ornatus suggests that this developmental strategy applies to this species too.[1][3]

Habitat and conservation

Allobates ornatus is known from disturbed lowland rainforest and humid montane forest at elevations of 350–680 m (1,150–2,230 ft) above sea level. Specimens have been found in leaf litter during the daytime. The ecology of this species is otherwise unknown. Specific threats to it are unknown, but habitat loss is a potential threat.[1]

Herpetologie

Allobates ornatus is een kikkersoort uit de familie van de Aromobatidae. De wetenschappelijke naam van de soort is voor het eerst geldig gepubliceerd in 2002 door Victor Morales.[2]

De soort is alleen nog gevonden op twee locaties bij Tarapoto in het San Martín departement in Peru.[3] Allobates ornatus leeft in het regenwoud. De vrouwtjes leggen waarschijnlijk hun eieren in de grond en mannetjes vervoeren vervolgens die eieren naar water, waar de dieren verder ontwikkelen.
