Camponotus aktaci Karaman, C., 2013 |
A forest species preferring luminous deciduous forests, noted also from olive plantations, beaches with several large deciduous trees e.g. poplars, rarely collected on leaves of shrubs in gardens inside tourist resorts. Nests under stones or in soil on the slopes of clay-slate ravines. Most sites are from low altitude to 500 m, the highest confirmed location was from southern slope of Mt. Olympus, a single speciemns was found on limestones rock on mountain pasture at an altitude 1315 m but perhaps it was an individual transported to so high altitude by the wind. (Borowiec and Salata 2022)
Identification
Karaman and Aktaç (2013) - C. aktaci is similar in appearance to Camponotus libanicus but can be distinguished from the latter by the red mandibles, antennae, and legs, absence of erect hairs on the occipital corners and scape, scarce erect hairs on the mesosoma, petiole and gaster, and densely reticulate petiole that appears subopaque to dull. The new species is distinguished from Camponotus aegaeus by a bare scape, thicker petiole, and scarce erect hairs on the entire body.
Salata et al. (2019) - A member of the Camponotus kiesenwetteri species group. Head and mesosoma uniformly black, gaster and legs yellowish-brown; metanotal groove absent; propodeum without posterior protrusion; body densely punctate, appears dull; base of scape without extension; whole body bears short, thin, pale, sparse and erect setae, and short appressed microsetae; petiolar scale thick.
The mostly yellowish-brown gaster and legs and short and sparse setation of head, mesosoma and gaster distinctly separates this species from other taxa in the kiesenwetteri species group.

- Key to Camponotus species of the subgenus Myrmentoma of Greece
Distribution
Salata et al. (2019) - Turkey: Adana, Bingöl, Diyarbakır, Elazığ, Malatya, Muğla.
Niche modeling showed highly suitable areas matching the species known distribution in Eastern Anatolian deciduous forests and in the central Anatolian steppe region where there are no current occurrence records. The westernmost specimen record, from Muğla Province, is projected as an area of low habitat suitability. Temperature seasonality contributed most to the distribution model.

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. |
Biology
C. aktaci was collected from the Pinus nigra Arnold forest and orchards of Prunus dulcis (Mill.) D.A. Webb between 1050 m and 1550 m altitude.
