Taxonomic notes.

The morphological taxonomic features observed in the studied specimens under an optical microscope show no differences from the Iberian specimens. However, a molecular analysis should be conducted to confirm whether these geographically distant populations belong to the same species.

Specific observations using scanning electron microscopy reveal large embase of antennal trichobothria (Fig. 2 a ), dense microdenticles (Fig. 2 b, d ) including rosette-type glands on all tergites (Fig. 2 f ), well-barbed macrosetae (Fig. 2 b ), and clothing setae with a single distal barb (Fig. 3 a, b ). Additionally, the stylus setae are smooth, with the apical one featuring two long basal denticles (Fig. 3 c ). Claws are simple, with a protuberance between them (Fig. 2 c, e ).

Habitat and distribution.

A soil-dwelling species known from a single locality in the western Subbaetic Mountains, southern Iberian Peninsula ( Silvestri 1932 a), and inhabiting colluvial scree slopes in central Iberia ( Sendra et al. 2017). Reported from Romania by Ionescu (1951, 1955) and Italy by Ramellini (1990).
