Pogonus meridionalis is a species of beetle of the family Carabidae. It is found in the Palaearctic region, with a wide distribution from the Iberian Peninsula to Siberia.
Adults reach a length of about .
The species can be found in saline areas colonised by plants of the Arthrocnemetea group, the genus Salicornia and the genus Vigna, but also in non-saline environments, as it is less halobiont than other species of the genus. The phenology of a population of P. meridionalis in Elton lake (Volgograd, Russia) was studied in 2008. It had a peak of adult activity in spring (AprilâÂÂMay), and the adults which emerged in one year coexisted with adults from the previous year.
