Description
A medium-sized green treefrog, males about 30 mm SVL, females unknown. Back green, with many dispersed, small whitish spots. Black pigmentations on back, head, and around the nostrils. Venter whitish, yellow in the middle, bluish on the throat. White lateral fringes on lower arm and tarsus. Iris yellowish with symmetrical reddish markings. Skin on the back smooth. Nostrils equidistant between eye and tip of snout. Tympanum indistinct. Tibiotarsal articulation reaches the nostril.

Webbing of the hand: a trace of webbing between 1 and 2i, 2e(1) 3i(2.5), 3e(1), 4(1). Webbing of the foot: 1(0.5), 2i/e(0.5), 3i(0.5-1), 3e(0.5), 4i/e(1), 5(0). Males with nuptial pads and a single, subgular vocal sac.

Similar species: Boophis albipunctatus is extremely similar in morphology and life colouration. It has fewer or no dark spots on the back, but mainly differs by call. Other species of the B. luteus- and B. rappiodes-group have many fewer or no white dots on the back.

Distribution and Habitat

An’Ala, Andasibe, Anjanaharibe, Masoala. It occurs around 900m asl in pristine rainforest (Glaw and Andreone 2008).

Life History, Abundance, Activity, and Special Behaviors
Males call at night from trees more than 3 m high along brooks in forest. They are often associated with Boophis luteus, from which the call of B. sibilans can be hard to distinguish in choruses.

Call (from the terra typica, 22°C): Composed of a series of melodious frequency-modulated whistling notes. Note duration is 111-167 ms (mean 147 ms), repeated after intervals of 721-1443 ms (mean 975 ms), the note repetition rate is 1-1.6/s and frequency ranges between 2.8 and 3.8 kHz. Sometimes such series are followed by note-groups (about 4-7 notes) with a higher repetition rate (4.4/s).

Eggs and tadpoles: Unknown.

Breeding takes place in streams (Glaw and Andreone 2008).

Trends and Threats
Data Deficient: uncertainties as to its extent of occurrence, status and ecological requirements. This species occurs in the Réserve Spéciale d’Analamazaotra (Glaw and Andreone 2008).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Urbanization
Habitat fragmentation
