The type locality is a mountainous region with a substantial variety of cultivated plants mainly rose (Rosa sp.) plantations.


Sharaf et al. (2018) - Aphaenogaster sarae is the most similar to Aphaenogaster finzii described from Federal Republic of Yugoslavia in regard to body size and the abundant long body pilosity. Aphaenogaster sarae can be readily distinguished from A. finzi by the paler colour, the larger eyes (EI 27–32), the rounded posterior head margin, the longer antennal scapes (SI2 148–187), and the thinner and more acute propodeal spines. Aphaenogaster finzi is dark brown with smaller eyes (EI 19), broad and straight posterior head margin, shorter antennal scapes (SI2 111), and the blunt and broadly based propodeal spines. Superficially, A. sarae appears similar to Aphaenogaster radchenkoi from Turkey, but A. sarae can be easily separated by the larger eyes (with about 12 ommatidia in the longest row), the longer scapes (SI1 123–167, SI2 148–187), the anteriorly and posteriorly narrow head, the thin and acute propodeal spines, and the densely granulate propodeal sides and dorsum, whereas A. radchenkoi has smaller eyes (with about 6 ommatidia in the longest row), shorter scapes (SI1 84–88, SI2 96–104), head narrower anteriorly than posteriorly, the propodeal spines short, blunt, and broadly based, and the propodeal sides and dorsum smooth.

Mesosoma. Promesonotum convex in profile; promesonotal suture present; metanotal groove impressed; propodeal dorsum nearly equal to declivity in profile; propodeal spines of moderate length (SPI1 18–26; SPI2 120–171) and acute; propodeal spiracle circular.

Node as long as broad in dorsal view, with convex dorsum and ventral margin in profile. Sculpture. Cephalic and mandibular surfaces smooth and shining; cephalic surface behind posterior-lateral clypeal margins with three distinct curved rugae; pronotum, mesonotal dorsum, petiole, postpetiole, and gaster smooth and shining, mesopleura and propodeum densely finely punctulate. Pilosity. Body surface with abundant long setae, ante-rior clypeal margin with two exceptionally long pairs of setae. Colour. Uniform light brown.
