Syntype workers, queen, Isola Rodi, Greece (Festa) (MSNG) [Syntype worker images examined, AntWeb, CASENT0905395, photos by Zach Lieberman, available on https://www.AntWeb.org] Diagnosis. 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). Distribution. Greece: North Aegean Islands, South Aegean Islands (Dodecanese), Central Macedonia, Eastern Macedonia and Thrace; Turkey: Adana, Afyon, Antalya, Aydin , Balikesir , Bilecik, Bursa, Canakkale , Denizli, Diyarbakir , Elazig , Izmir , Kirklareli , Kuetahya , Manisa, Mugla , Sakarya, Usak , and Yalova. The species was also recorded from North Macedonia ( Bracko et al. 2014 ) and Bulgaria ( Lapeva-Gjonova 2010 ). Comments. 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 and the most relevant character distinguishing both taxa is the shape of petiolar scale. Camponotus aegaeus has the scale thin (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. Both species appear to be vicariant taxa with a more westerly distribution of C. aegaeus and more a easterly distribution of C. libanicus ( Figs 24 , 32 ). Indeed, niche modeling for both species show similar areas with high suitability, especially along the south coast of Turkey and Cyprus. However, unlike C. libanicus , 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 .
