qui semblent être des formes originales du Chott El Hodna. Plusieurs investigations myrmécologiques ont été faites dans le même site de récolte à la recherche d’autres individus de la nouvelle espèce (2011, 2013, 2016 et 2019: données non publiées). Différentes méthodes d’échantillonnage, notamment les pots Barber, récolte à main, Berlese, lavage du sol et appâts alimentaires ont été utilisées, mais aucune de ces méthodes n’a pu apporter de nouveaux spécimens. C’est pourquoi nous qualifions cette espèce de «rare et cryptique ». Medbah, qui est un site à conservation Ramsar, subit une forte dégradation environnementale ces six dernières années. Une usine agroalimentaire s’est installée en 2015 (distante de

). Les rejets ménagers d’eaux usées de la population environnante sont déversés directement dans la sebkha. Nous signalons aussi dans ce même site des activités agricoles récentes (labours, pompage des eaux souterraines, l’utilisation des produits phytosanitaires et des fertilisants qui polluent l’environnement) ainsi qu’une activité pastorale intense (pâturage du cheptel ovin et caprin) qui rajoutent plus de pression. Ces différents facteurs sus-cités contribuent à la perte de l’habitat, ce qui augmente le degré de vulnérabilité de la fourmi en question. En conséquence, nos recommandations s’adressent à l’UICN pour le classement de cette espèce dans la liste rouge des espèces en danger. Selon l’UICN (2018) le classement des espèces dans les catégories d’espèces menacées s’opère sur la base des cinq critères d’évaluation suivants: (A) déclin de la population; (B) aire de répartition réduite; (C) petite population et déclin; (D) très petite population; (E) analyse quantitative. Il suffit qu’au moins un des critères A à E soit rempli pour qu’une espèce soit classée dans l’une des catégories En danger critique (CR), En danger (EN) ou Vulnérable (VU). Le cas de la nouvelle espèce remplit le Critère D: Population très petite ou restreinte, car elle présente un nombre d’individus matures inférieur aux seuils proposés (moins de 50 individus matures).
