Barretonus auarita Garcia & Oromi, 2019

New record.

La Palma island. Barlovento, Punta Salvaje (28°49'25.34"N, 17°46'17.29"W, 124 m a.s.l.), 2 exx., 18 October 2019, sieving deep leaf litter under Euphorbia balsamifera , R. García leg. (RGB).

The Macaronesian endemic genus Barretonus Roudier, 1958 includes four species from Madeira and two from the Canary Islands. In the recent description of the last species ( García et al. 2019), B. daute from Tenerife was considered to have a few ommatidia, but this is a wrong statement that has to be amended in that description as well as in Table 2. Actually, all species of Barretonus are eyeless, since also the statement by Folwaczny (1972) that B. minor Folwaczny, 1972 and B. major Folwaczny, 1972 had also highly reduced eyes was wrong, which has been confirmed after the revision of the types by Peter Stüben (pers. comm.). Recently, we have collected some individuals of B. auarita on a new locality situated between other two already known, which indicates that this species must be well distributed along the eastern and northern coast of the island.
