Forty-four members of this group are recognised and described, and an illustrated identification key to this group is also presented. One species is raised to species level: P. litigiosa Forel, 1892 stat. nov. Pheidole veteratrix angustinoda Forel, 1892 syn. nov. is proposed as a junior synonym of Pheidole veteratrix Forel, 1891. Worker castes are also described and lectotypes designated for P. litigiosa Forel, 1892, P. sikorae Forel, 1891, and P. veteratrix Forel, 1891. The following 41 new species are described: P. alina sp. nov., P. ambohimanga sp. nov., P. analavelona sp. nov., P. andohahela sp. nov., P. anomala sp. nov., P. anosyenne sp. nov., P. antranohofa sp. nov., P. beanka sp. nov., P. befotaka sp. nov., P. dasos sp. nov., P. flavominuta sp. nov., P. gracilis sp. nov., P. haboka sp. nov., P. havoana sp. nov., P. hazo sp. nov., P. itremo sp. nov., P. joffreville sp. nov., P. kely sp. nov., P. lavasoa sp. nov., P. mahamavo sp. nov., P. mainty sp. nov., P. mamiratra sp. nov., P. manantenina sp. nov., P. masoandro sp. nov., P. mavohavoana sp. nov., P. midongy sp. nov., P. mikros sp. nov., P. mivory sp. nov., P. nitidobruna sp. nov., P. parvula sp. nov., P. parvulogibba sp. nov., P. renirano sp. nov., P. sava sp. nov., P. sofia sp. nov., P. sparsa sp. nov., P. tampony sp. nov., P. trichotos sp. nov., P. tsaravoniana sp. nov., P. vadum sp. nov., P. volontany sp. nov., and P. vony sp. nov. At present, there are 109 valid species and subspecies of Pheidole known from Madagascar, but this number is expected to increase with upcoming taxonomic revisions of the species groups not revised in this study.
