Crematogaster subdentata

Stukalyuk (2015) Abstract - A population of Crematogaster subdentata, a potentially invasive species of ants, which is new for the Crimea, was found in the village of Mykhailivka (Saky district, the Crimea, Ukraine). This species appears to be brought into the Crimea from Central Asia. The invasion began 9-12 years ago. The following ecological-ethological features characterizing the C. subdentata habitation in the region studied are described: the density of colonies related to the time of the invasion, the structure of forage areas, and the cycle of diurnal activity. Four colonies of this species were recorded; they differed in the age and structure of the forage areas. The species C. subdentata may be considered as a potentially dangerous invasive species, which is able to damage forests, parks and gardens, as well as wooden constructions.

Pashaei Rad et al. (2018) found this species in Iran on parkland ground and trees in a moderate rainfall area.
