Distribution Morocco , southern Spain , southern France , Corsica , Sardinia and Tuscany. New record for the Rif region. Remarks In Morocco two species of Lucasius have been recorded: L. myrmecophilus Kinahan, 1859 , originally described from Algeria ( Kinahan 1859 ); and L. pallidus , originally described from southern France , Sicily, southern Spain and Algeria . In Sicily this species was confused with Mica tardus ( Budde-Lund, 1885 ) and, according to Caruso and Di Maio (1996) , it is not present. Achouri et al. (2008c) cite L. myrmecophilus from the Oued Laou basin. The specimens from the same area examined by us definitely fit the description of L. pallidus , but the differences of this species with L. myrmecophilus are still unclear. According to Vandel (1962) and Schmölzer (1965) L. myrmecophilus differs from L. pallidus in having a smooth instead of granulated dorsum, but in the original description by Kinahan (1859) and in the redescription by Budde-Lund (1885 , p. 135) it is clearly stated that the dorsum of the body is granulated. Therefore there is a possibility that the two species are synonymous, but a re-examination of the type material of L. myrmecophilus is necessary to confirm this hypothesis. For diagnostic characters of L. pallidus see Vandel (1962 , p. 651, Figure 321).
