Pheidole pallidula tasdelenia Özdikmen, 2010
Replacement name for Pheidole tristis Forel, 1907 [Junior secondary homonym of Pheidole tristis S mith, 1858].
It was described from Kairouan, Tunisia on the basis of a single specimen considered by Forel as a microgyne (2.6–2.8 mm total length). The status of this problematic specimen cannot be cleared up without very extensive investigations of the Tunisian Pheidole populations.
