The sister taxon of Ischnocnema parva according to the original publication and Padial, Grant, and Frost, 2014, Zootaxa, 3825: 122. Taucce, Canedo, Parreiras, Drummond, Nogueira-Costa, and Haddad, 2018, Mol. Phylogenet. Evol., 128: 123–146, transferred it to the Ischnocnema parva series and suggested that this species is the sister of the Ischnocnema parva, Ischnocnema venancioi, and Ischnocnema guentheri species series. Silva-Soares, Ferreira, Ornellas, Zocca, Caramaschi, and Cruz, 2021, Zootaxa, 5082: 214, removed Ischnocnema nanahallux from any species series and regarded it incertae sedis.
