Description
Habitus (Fig. 2E). Length: 6.0–8.0 mm. Antennae dark, with the base of the antennomeres (especially the 2–5) slightly lighter. Palps dark, but lighter in the base and/or apex. Anterior angles of the pronotum protruding; hind angles straight. Lateral sulcus of the pronotum marked and narrow. Surface of the pronotal disc slightly rugose. Legs brown, but femora the base and apex of the tibiae or the dorsal surface of the tarsi can be darkened (in this last case, sometimes with a slight metallic sheen). Median lobe of the aedeagus narrow, regularly arcuate from the base to the apex (Fig. 3J).
Chorology
Species distributed along the Mediterranean coast of South Europe from Spain to Albania (Bousquet 2017), also present in Cyprus (Jeanne 1986). In Bulgaria, it is associated with the coast of the Black Sea (Gueorguiev & Gueorguiev 1995).
Ibero-Balearic distribution (Fig. 5D): in the Iberian Peninsula, the species is known from some coastal and saline environments of Alicante (E Spain) and Catalonia (NE Spain). Eiroa et al. (1988) reported one record from the Playa de Barra (Pontevedra, Galicia, NW Spain), but it was based on incorrect identification of P. chalceus (Campos Gómez & Novoa 2006). The species has been reported, with no precise locality, from the Balearic Islands (Menorca; Compte Sart 1968; Zaballos & Jeanne 1994).
Biology
The species occupies environments where plants of Arthrocnemetea grow (Sauleda 1985). The only comments about its phenology come from Ratti (1994), who suggested that, in some populations along the Adriatic coast, the different life phases of this species can overlap in the same year, so it cannot be exclusively considered an annual species.
