The ants were collected on ground around shrubs and from shrub leaves and stems. Locality on Karpathos, Olympos was placed 429 m a.s.l. in dry, stony and rocky area with sparse shrubs. First locality on Spoa-Mesochori rd. was on a rocky slope, above olive orchard, overgrown by shrubs. Second locality on Spoa-Mesochori rd. was near a road, opposite the Spoa-Mesochori rd. locality, area was overgrown by Mediterranean shrubland. Locality near Agios Nikolaos was located above the village. The vegetation at this locality is a Mediterranean shrubland and pine forest. Locality near Achamandria was on a dry slope overgrown by Mediterranean shrubland and isolated pine trees. Locality near Trachanammos was in a sandy valley created by intermittent river, overgrown by Mediterranean shrubland. Nest was located in the soil, under stone beneath shrubs.

Identification

Salata & Borowiec (2015) - Crematogaster erectepilosa differs from all species from the north-eastern part of the Mediterranean Basin, except Crematogaster cypria and Crematogaster gullukdagensis, in that the first gastral tergite bearing numerous erect setae. Crematogaster cypria is well distinguished by shorter propodeal spines and mesonotal keel. C. gullukdagensis is very similar but differs in having the antennal scape predominantly with subappressed and suberect setae, while in C. erectepilosa the setae on scape are mostly erect. Head in full face view in C. erectepilosa appears round, while in C. gullukdagensis it is slightly square. Eyes in C. erectepilosa are more round (EI 74.3 ± 2.3 [71.5-78.8]) and in C. gullukdagensis they are more oval (EI 69.5 ± 3.1 [63.4-73.6]). Body ground colour in C. erectepilosa. is darker, yellowish-brown to brown, in C. gullukdagensis yellowish to pale yellowish-brown. Propodeal spines of C. erectepilosa in most specimens are slightly curved down, while in C. gullukdagensis propodeal spines are mostly straight, spine at base slightly thicker in C. erectepilosa and thinner in C. gullukdagensis. Sides of pronotum in C. erectepilosa in most specimens have fine longitudinal striation, while in C. gullukdagensis they are mostly without striation, smooth and shiny.
