Bolívar leg.; MNCN . Description Habitus ( Fig. 1B ). Length: 4.0–5.0 mm. Head with a similar colour to the body tegument. Anterior angles of the pronotum obtuse and barely protruding. Base of the pronotum clearly narrower than the anterior margin of the elytra; the punctuation of the base is hidden by longitudinal clefts, so the surface of this region presents a striated appearance. Elytra punctuation deep. Median lobe of the aedeagus ( Fig. 3B ) narrower and with the apex more developed than in P. testaceus . Fig. 1. Habitus. A .

Chorology Mediterranean coast of South Europe, from Spain to Greece (including Malta ) and North Africa ( Compte Sart 1968 ; Magrini & Schembri 1997 ; Bousquet 2017 ). Ibero-Balearic distribution ( Fig. 4B ): in the Iberian Peninsula, the species is present discontinuously along the Mediterranean coast, from Cádiz to Tarragona ( Spain ), and in saline localities of the Ebro valley (NE Spain ) and the Southern Sub-plateau (SE Spain ). The species has been reported, with no precision, from Algarve (SW Portugal ; Zaballos & Jeanne 1994 ), Los Monegros Desert (NE Spain ; Vives & Vives 1978a , 1981 , 1999 ), saltmarshes of Alicante (E Spain ; Vives & Vives 1978a ) and a saltmarsh in Toledo (SE Spain ) ( Vives & Vives 1981 ). We examined collection material from Huelva (SW Spain , with no precise locality), a territory from which P. gracilis has never previously been reported. In the Balearic Islands , Pogonistes gracilis is present in Mallorca, Menorca and Ibiza. Fig. 2. Habitus. A . Pogonus ( Pogonus ) gilvipes Dejean, 1828 . B .

Biology The species inhabits coastal and interior regions equally ( Bolívar 1919 ; see Vives & Vives 1978a , 1978b , 1981 ). Imagoes are active during spring, principally from March to July, but some records are dated from other months such as November ( Andújar et al . 2002 ). Pogonistes gracilis can be found in direct contact with water when it takes refuge under the rocks on the shores, in damp and saline environments where it occurs ( Ortuño & Marcos 2003 ).
