Overview

Comprehensive Description

Description

A large tree frog. M up to 73 mm, F up to 81 mm. Snout vent length is 43-73 mm in males and 68-81 mm in females. Back color is live green, green-grey or brownish, sometimes with brownish spots (especially in females); in preservative violet. Flanks often marbled. A distinct white line along the upper lip and white lateral fringes along lower arm and tarsus was observed. Legs are with indistinct dark bands. Venter is whitish to yellowish. The iris is light brownish to greyish. Skin on the back is smooth or partly granular on head and neck, very granular in males during the reproductive period. Nostrils are equidistant between tip of snout and eye. Tympanum/eye ratio is about 1/2. Tibiotarsal articulation reaches tip of snout. Webbing of the hand 1(1), 2i(1), 2e(0), 3i(1), 3e(0), 4(0); foot completely webbed. Males are found with a large prepollex, nuptial pads on 1. and 2. finger and a paired subgular vocal sac. Breeding males have large tubercles covering most of dorsum, and with black keratinized spiiny tubercles on throat and chest.

Similar species: Other large Boophis (e.g. B. goudoti, B. opisthodon) are not green and have much less webbing on the hand. B. luteus and B. elenae have no white band along the upper lip.

Justification
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Life History, Abundance, Activity, and Special Behaviors

Habits: Calling specimens were observed at night in very slow-moving water,

Adult specimens were found in vegetation near streams in primary forest. Calling males were heard in August and March. They were sitting about 3 m high in vegetation, sometimes upto 30 m away from the stream. The intestine of one female contained remains of insects (probably coleopterans and heteropterans).

Eggs: One gravid female from Benavony with snout vent length 68 mm found in March contained 421 eggs of about 2.5 mm diameter, which were yellowish with a blackish cap.

Breeding takes place near streams and small trickles of water (Nussbaum et al. 2008).

Threats

Major Threats
Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing, and expanding human settlements. It is collected for the international pet trade in very small numbers, but this is very unlikely to constitute a threat to the species.
