[1][3][4][5] Both the generic and specific names honour Rose Marie Antoinette Blommers-Schlösser, a Dutch herpetologist and entomologist[6] who collected the type series.

[1][3][6] Blommersia blommersae is a small frog that can grow to 22 mm (0.9 in) in snout–vent length.

The colouration is variable:[5] the dorsum is gray or light brown with darker, irregular spots, forming an inter-ocular bar and a V-shaped pattern on the scapular region.

[5] Blommersia blommersae occurs in swamps in or near forest at elevations of 800–1,780 m (2,620–5,840 ft) above sea level.

Breeding takes place in swamps; the eggs are laid on leaves above water.
