[1] Blanus mariae is found in the southwestern Iberian Peninsula, mainly in the southern half of Portugal and in the spanish autonomous communities of Extremadura and western Andalusia.

[3] The specific name, mariae, is in honour of Maria del Rosario Aguilar Tortajada (1914–2002), the grandmother of Eva María Albert, one of the scientists who described this species.

[1][4] Blanus mariae has an average snout–vent length of 175 mm (6.9 in).

The body colour is pale pink to dark brilliant purple, with a reticulate pattern caused by the inter-segmental sutures.
