Specimen Labels

There are only scarce data about the ecology of this species. We found them in mixed and pine forests, nesting under the stones or in humus, at the base of shrubs. Other authors (Forel, 1911; Müller, 1923; Zimmermann, 1934) found this species mostly in tree cavities. Workers are generalized omnivores. (Karaman 2010)

Borowiec (2014) notes that this species needs revision as recent collections suggest it is a complex of closely related taxa.


A member of the Crematogaster scutellaris group.

Karaman (2010) - TL= 4.2-5.0 mm. Body sculpture and hairiness are the same as in Crematogaster schmidti. Exception is the frontal triangle which is not completely smooth, but striated with 3-4 longitudinal striae. The head, thorax, appendages and petiole nodes dark reddish to brown, the head occiput and the first segment of the funiculus dark brown. Gaster dark-brown to black.

Keys including this Species


Karaman (2010) - Northern and eastern bank of Mediterranean Sea including islands in Aegean Sea. Altitude: 0-230 m a.s.l.

This is a common species, known from all Greek provinces, but our unpublished data on molecular variability of Greek populations showed that with great probability in this area occur three cryptic taxa. Their taxonomic status will be clarified after analysis or all studied samples (Borowiec et al., 2022).

Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.

Taxonomic Notes

Eastern populations of this species differ slightly from western ones and with great probability this taxon is a complex of two cryptic taxa. Until the revision of this species group the name C. ionia has been used for material from Jordan (Borowiec & Salata, 2020).

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
