Description
A brown, large treefrog; males 52-57 mm, females 85 mm. Back uniformly beige or light brown. Temporal and loral regions dark brown. Often a white band along the upper lip. Dark bands are usually present on the limbs. Venter cream. Skin on the back smooth in females, sometimes granular in males. Nostrils nearer to tip of snout than to eye. Tympanum/eye ratio is 3/4. Tibiotarsal articulation reaches the nostrils. Hand without webbing; webbing of the foot 1(0), 2i(1), 2e(0), 3i(1), 3e(0), 4i/e(1), 5(0). Males with small blackish nuptial pads and a moderately distensible, single subgular vocal sac.

Similar species: Other species of the B. tephraeomystax group are smaller. Species of Guibemantis have an outer metatarsal tubercle (absent in Boophis). Other large Boophis (B. albilabris, B. goudoti, B. periegetes) have at least some webbing between the fingers.

Life History, Abundance, Activity, and Special Behaviors
Habits: Generally found outside the forest. Males call from the vegetation of stagnant, shallow pools. Axillary clasping was observed between collected males.

Call (from Nosy Boraha and Tolagnaro): Consists of a series of normally 2-5 unharmonious notes and is repeated after 850-1200 ms; note duration is 50-100 ms and duration of intervals between notes 70-130 ms. Call repetition rate is about 42/min. During a call series the number of notes can increase, for example from 2 in the first call to 5 in the fifth call. Frequency ranges from 1 to 2.5 kHz.

Eggs and tadpoles: Unknown.
