This alpine Puto species was described from various plants in the Hautes Alpes of southeastern France . Puto alpinus was described based on the third-instar female and was synonymised with P. janetscheki by Marotta and Tranfaglia (1993) . The claws are without denticles, but other features of the adult female are typical for Puto species, including the presence of a pair of basal spurs on each claw. We agree with the illustration of this species given by Marotta and Tranfaglia (1993) but we provide additional information on the antennal sensilla in Table 1.
