Description

provided by AmphibiaWeb articles
General body shape rather stout. SVL 20-27 mm (M 21-22 mm, F 24-25 mm). Upper head surface, dorsum and flanks usually blackish without recognizable dorsolateral colour border. Yellowish rostral stripe present. Femur and humerus yellow to green, this colour extending as large flank blotches onto the flanks and sometimes onto the dorsum. Distinct orange flashmarks present. Tibia, tarsus and foot orange, with or without blackish crossbands and marblings. Iris mostly containing light pigment in its upper part. Rostral stripe often in contact with flank blotch. Specimens of unknown origin in the pet trade were more variable yellow colour in varying extension can sometimes be present on the dorsum. All intermediate states from a few yellow spots, to a reticulated yellow marbling or a dense yellow speckling are known. A greenish frenal stripe, often interrupted, can be present as well. Other specimens are nearly uniformly yellow dorsally and ventrally, with only a few blackish spots and marblings. In these specimens, the more distinct yellow surface in the flank blotch area is reminiscent of the typical colouration, but it is not clear whether they really are conspecific with M. madagascariensis. Venter, throat and forelimbs black with light markings (mostly whitish-blue, sometimes yellow to green). These being generally rather large, rounded, and situated posteriorly on the venter. Distinct horseshoe marking present, more extended in males. Femur, tibia (except flashmark area), tarsus and foot often uniformly orange, in other specimens with areas of black and yellow (the latter corresponding to yellow colour on the dorsal surface). Areas of femoral “glands” often darkly pigmented. In some specimens, femur nearly totally black with blue spots. In “variable” specimens, entirely ventral pattern sometimes replaced by a dense yellow marbling. Variation: Genetically, specimens from the Ranomafana area (in the general region where the types have been collected) are not placed in one clade with specimens from the Moramanga area. These south-eastern specimens which are to be considered as typical M. madagascariensis have a smaller body size but otherwise are not distinguishable from the central-eastern specimens by morphology or colouration. Similar species: M. baroni is more slender and has no reddish flashmarks, M. pulchra is less colourful dorsally and has no distinct yellowish rostral stripe.Taken with permission from Glaw and Vences (2007).

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Habits: Poorly known, along streams in primary rainforest. Active during the day on the ground. Calls: Short chirps, arranged in less regular series. Breeding occurs in streams, where larvae develop (Andreone and Glaw 2008).

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Vulnerable: extent of occurrence is less than 20,000 km2. Its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in eastern Madagascar.Its presence is not confirmed in any protected areas, but it occurs close to Parc National de Ranomafana. There is a need for careful regulation of the trade in this species (Andreone and Glaw 2008).

Madagascan mantella

provided by wikipedia EN

Mantella madagascariensis, common names Malagasy painted mantella, Madagascan mantella, Madagascar golden frog, Malagasy mantella and painted mantella, is a species of frog in the family Mantellidae.

Distribution

This species is endemic to Madagascar. It is present in the East-central Madagascar in upland locations from near Niagarakely south to Ranomafana, at an elevation of 700–1,050 metres (2,300–3,440 ft) above sea level.[2] It is threatened by habitat loss and it may be threatened by commercial collection.

Habitat

Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and rivers.[3]

Description

Mantella madagascariensis can reach a body length of 21–22 millimetres (0.83–0.87 in) in males, of 24–25 millimetres (0.94–0.98 in) in females. These tiny but stout frogs are rather variable in color and markings, as they are irregularly streaked in black and yellow. Usually they have a blackish body, but the dorsum is commonly black. A green or yellowish rostral stripe is running along the head. Femur and humerus are usually yellow to green, while tibia, tarsus and foot are reddish-orange, with blackish patches. Blotches of yellow-green color extends to flanks close to the forelimbs.[4][5]

Some authors consider Mantella madagascariensis a complex of cryptic species.[6]

This species is closely related to Mantella pulchra and very similar to Mantella baroni.[4][1]

Biology

Little is known about the biology of the species. These frogs are terrestrial and are active on the ground during the day. They prefer forest and forest edge, especially along streams. Breeding occurs in streams. Females lay eggs on land, but the larvae develop in water streams.[3] Like all Mantella species, these frogs has several toxic alkaloids in its skin.[7]
