Camponotus aegaeus

A ground-nesting species.

Identification
Salata et al. (2019) - A member of the Camponotus kiesenwetteri species group. Head, mesosoma, and gaster uniformly blackish-brown to black; metanotal groove absent; propodeum without posterior protrusion; body densely punctate, appears dull; base of scape without extension; whole body bears long, thick, pale, dense and erect setae, and short appressed microsetae; petiolar scale thin (PI > 1.50).

The almost completely blackish-brown to black body and regularly arched (in lateral view) mesosoma cluster this species with Camponotus libanicus. At first glance both species look extremely similar. The most relevant character distinguishing both taxa is the shape of petiolar scale. Camponotus aegaeus has a thin scale (PI > 1.50) with a feebly convex anterior surface, while in C. libanicus the scale is thick (PI < 1.42) with a strongly convex anterior surface.

Distribution
Salata et al. (2019) - Greece: North Aegean Islands, South Aegean Islands (Dodecanese), Central Macedonia, Eastern Macedonia and Thrace; Turkey: Adana, Afyon, Antalya, Aydın, Balıkesir, Bilecik, Bursa, Çanakkale, Denizli, Diyarbakır, Elazığ, İzmir, Kırklareli, Kütahya, Manisa, Muğla, Sakarya, Uşak, and Yalova. The species was also recorded from North Macedonia (Bračko et al. 2014) and Bulgaria (Lapeva-Gjonova 2010).

The kiesenwetteri species group contains taxa of the subgenus Myrmentoma that are distributed almost exclusively in the Aegean. The two exceptions, Camponotus aegaeus and Camponotus libanicus, collectively extend the group's distributional range into Asia Minor and the Near East. These two species appear to be vicariant taxa, with C. aegaeus to the west and C. libanicus to the east. Niche modeling for both species show similar areas with high suitability, especially along the south coast of Turkey and Cyprus. However, C. aegaeus has not been recorded from the island. Solar radiation was the variable that contributed the most to the niche model of C. aegaeus.

Distribution based on Regional Taxon Lists
