Description
A small terrestrial microhylid, males measure about 15 mm. Back in adults
usually uniformly greyish. Young with two inverted V-shaped markings on the
greyish back. If distinct, the tubercles on the back are whitish. Skin on the
back is smooth, often with a few, rather large, tubercles. Tympanum rather
indistinct, tympanum/eye ratio less than 1/2. Tibiotarsal articulation reaches
the eye. Four fingers and 5 toes are present. There is no recognizable digital
reduction. Males with a distinct, largely distensible, single subgular vocal
sac.
Males called mainly in the evening, and also after sunset. Call consists of
a single, chirping note, louder than in Stumpffia pygmaea. Calls are
arranged in series, which last several minutes. Call duration is about 95-101
ms (mean 97 ms, n=10), intervals between the calls last 1375-2365 ms (mean
1670 ms, n=9), call repetition rate is about 45/min and frequency is 4.7 kHz.
Calls from Montagne d'Ambre were similar.
Mainly S. tetradactyla (digital reduction!) and S. psologlossa
(skin always smooth, different advertisement call). S. sp. from Sambava
is very similar. S. tridactyla and S. pygmaea have shorter
hindlimbs. S. grandis and S. roseifemoralis are larger.
