Own material: Males from Ankaratra measure 16 mm, males from Andringitra 15.5-17.0 mm. Femoral glands are indistinct. The colouration is typical: Three dark brown stripes on a light copper-brown back.

Life History, Abundance, Activity, and Special Behaviors
Habits: Calling males were found hidden under vegetation in sun-exposed swamps in January and February. The calls were heard between 15.00 h and 21.30 h.
Call (from Andringitra): The structure of the call is very similar to the call of B. grandisonae. Two different unharmonious note types exist. A long note (duration about 330-350 ms) is followed by a series of 4-8 click-note-pairs. Each note-pair (duration 35-40 ms) consists of one longer (ca. 20 ms) click followed by one shorter (ca. 10 ms) click. Intervals between note-pairs are ca. 30 ms, between both notes of one note pair ca. 15 ms. Frequency is between 3.6 and 4.8 kHz.
Calls from Manjakatompo and Ankeniheny are very similar. At Manjakatompo sometimes series of long notes (type 1) were emitted with a repetition rate 0.6/s. Such series could be triggered by play-back of conspecific calls, indicating a territorial function of this note type.
Eggs and tadpoles: Unknown.
