Despite intense sampling of caves and MSS over decades in Tenerife, all known specimens of O . hephaestos have been collected in Cueva del Viento-Sobrado, the largest lava tube in the European Union. Some individuals of this blind weevil have been recently collected in Cueva del Sobrado, on the cave floor under a large crack of the ceiling through which roots emerge and the clay from the overlying soil percolates. This seem to confirm that this species is a radicicolous edaphobiont which appears in caves accidentally, or in transit during its movements among the subterranean soil layers, such as Alonso-Zarazaga (1987) suggests. The specimens collected over last two decades are more variable in body size than those used for the description of the species, so the total length now varies from 2.80–3.56 mm ( s.r. ) and the maximum width of elytra from 1.16–1.44 mm .
