Diagnoses
Tegument bronze in most Ibero-Balearic individuals, but blue with metallic sheen in the southern populations of the peninsula. Pronotum markedly convex, with the base clearly wider than the anterior margin and small setae inserted in the anterior angles. Elytra sub-oval and slightly convex.

Description
Habitus (Fig. 1D–E). Length: 5.5–7.0 mm. Antennae and palps dark brown, lighter at the base of antennomeres (from the second to the last) and at the apex of the last palpomeres. Pronotum with short lateral sinuosity and the base sub-rectilinear; lateral sulcus narrow; hind angles well marked and straight or slightly sharp. Legs brown, with the femora darkened (in southern populations, almost the entire legs darkened). Median lobe of the aedeagus arcuate, with the apex rounded and not narrowed (Fig. 3D).
Chorology
The subgenus Pogonoidius is well represented in the Palaearctic Region (Bousquet 2017). The species P. meridionalis is a Palaearctic element with a wide distribution from the Iberian Peninsula to Siberia (Bousquet 2017).
Ibero-Balearic distribution (Fig. 4D): in the Iberian Peninsula, the species is present in the meridional extreme, in the Segura basin (SE Spain), some localities of the Catalonian coast and in lagoons and saltmarshes of the Southern Sub-plateau (SE Spain) and Central Spain. It has been reported from Portugal, with no precise locality, by Serrano (2002).
Biology
The species can be found in saline areas colonised by plants of the Arthrocnemetea group and the genus Salicornia L. (Sauleda 1985; Vigna Taglianti & Bonavita 1994; J. Muñoz-Santiago pers. obs.) but also in non-saline environments, as it is less halobiont than other species of the genus (Sauleda 1985). This suggestion is supported by the presence of the species in the Embalse de Valmayor (Madrid, Spain; Ortuño & Toribio 1996), a freshwater body. The phenology of a population of P. meridionalis in Elton lake (Volgograd, Russia) was studied by Matalin & Makarov (2008): it had a peak of imaginal activity on spring (April–May), and the imagoes which emerged on one year coexisted with imagoes from the previous year, so it is not an annual species. The large number of imagoes in spring was also observed by Sauleda (1985).
