The description is based upon the holotype. It is a male in excellent preservative condition. SVL 32.3 mm. Snout pointed, head longer than wide. Loreal region rather concave, nostrils not distinctly projecting, situated nearer to the eyes than to the tip of snout. Tympanum distinct, half the diameter of the eye. Vomerine teeth arranged in two slightly oblique oval groups behind the choanae. Hind legs overlap about 2 mm when curved at right angles; the tibiotarsal articulation reaches the tip of the snout. Finger length: 1 < 2 < 4 < 3. Unwebbed fingers with digital expansions about the same size of the tympanum diameter. Subarticular tubercles, as well as the tubercle at the basis of the pollex, visible. Lateral metatarsalia separated. Toe length: 1 < 2 < 3 < 5 < 4. Foot webbing: 1(1), 2i(0.75), 2e(0), 3i(1), 3e(0.75), 4i(2), 4e(2), 5(0.5). Inner metatarsal tubercle length = 1.7 mm; wart-like outer metatarsal tubercle. Dorsum and belly rather smooth. Femoral glands distinct, 8.6x3.2 mm, distance between inner margins of glands on opposite femurs = 1.5 mm.In life the dorsum has a yellowish - light brownish ground colour. Blackish blotches are present on the back, forming a reticulation on the head and loreal region. The upper surface of humerus and forearm is smooth, more or less of the same colouration of the dorsum with dark transverse bands. Fingers and toes with dark-whitish transverse bands; fingertips whitish. Flanks, as well as the area between the foreleg insertion and the jaw, pink; the yellowish dorsum colouration continues onto the pink flanks with isolated yellowish spots.

Andohahela. It occurs between 300-600m asl in crevices among boulders and rocky areas in pristine forest close to flowing waters (Nussbaum et al. 2008).

Habits: The single known specimen was found in low elevation rainforest next to a small cave built by large overhanging boulders along a small shaded stream. Calls: A trill composed of 3-4 pulses. Breeding takes place in streams (Nussbaum et al. 2008).

Endangered: extent of occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in southeastern Madagascar. It occurs in Parc National d'Andohahela (Nussbaum et al. 2008).

Spinomantis brunae (common name: Bruna's stream frog) is a species of frogs in the family Mantellidae. It is endemic to Madagascar and known from the Anosy Mountains in southeastern Madagascar.
