M 22-26 mm, F 26-32 mm. Tibiotarsal articulation reaches at most the nostril. Fifth toe shorter than third toe. Femoral glands in males often small and not very prominent. Frenal stripe mostly rather distinct and well defined but usually fading before reaching the nostril. Ventrally often with a dark throat with a thin light median line (Glaw and Vences 2007). Variation: As currently understood this species contains various cryptic species, among them a form from the Ranomafana area (Glaw and Vences 2007).Taken with permission from Glaw and Vences (2007) and Glaw and Vences (2008).

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Habits: A locally very common species in low-altitude rainforests along the east coast. Males call during the day from dense vegetation along streams (Glaw and Vences 2007).Calls: From Foulpointe. Slow series of 16-21 relatively long pulsed notes (Glaw and Vences 2007).

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Abundant but decreasing. This species is found within several protected areas. Can tolerate slightly disturbed forest. The main threat is habitat loss due to subsistence agriculture, logging, charcoal manufacture, invasion and spread of eucalyptus, grazing and expanding human settlement (Glaw and Vences 2008).

Mantidactylus charlotteae

provided by wikipedia EN

Mantidactylus charlotteae is a species of frog in the family Mantellidae.[1][3] It is endemic to Madagascar and found in the eastern part of the country in the coastal rainforest belt between Marojejy in the north and possibly as far as Andohahela in the south.[1]

Description

Males measure 22–26 mm (0.87–1.02 in) and females 26–32 mm (1.0–1.3 in) in snout–vent length. The body relatively slender. The head is long with rounded snout. The tympanum is distinct. The limbs are slender. The fingers are without webbing whereas the toes are webbed. The back is reddish brown in colour and without markings. There are reddish dorso-lateral glandular ridges. The flanks are blackish, with a sharp border towards the dorsum.[2]

Habitat and conservation

Its natural habitats are pristine or slightly disturbed rainforests at elevations of up to 600 m (2,000 ft) above sea level. It is a terrestrial species that is often found near streams where. It breeds in streams but lays its eggs on land.[1]

Mantidactylus charlotteae is a very abundant species, although it is suspected to be decreasing because of habitat loss and deterioration. These threats are driven by agriculture, timber extraction, charcoaling, spread of eucalyptus, livestock grazing, and expanding human settlements. However, it occurs in several protected areas.[1]
