[4] The original descriptions of this genus and this species are based on multiple specimens, including both adult and immature specimens of each sex, collected from caves near Tourettes-sur-Loup and in Saint-Jeannet near Vence, both in the Provence-Alpes-Côte d’Azur region of southern France in the Maritime Alps.

[4] The adult female has two more segments and consequently four more pairs of legs than usually observed in the order Polydesmida.

[5][2] Like other members of the genus Devillea, this species is very small and features an exoskeleton highly sculptured with tubercles.

The sternites are long and narrow and feature cross-shaped depressions in which the transverse groove is deeper.

The dorsal surface of the telson has no large tubercles, instead featuring several pairs of smaller protuberances crowned with setae.
