Camponotus gestroi

This species populates dry open areas, and builds its nests in soil, often under rocks (Radchenko 1997).

Identification
Ionescu-Hirsch (2009) - Radchenko (1997c) included this species in the C. gestroi species complex of the Camponotus lateralis species group. Other species in the complex are Camponotus rebeccae, Camponotus kurdistanicus, and Camponotus vogti. Camponotus gestroi differs from these species by having erect setae scattered all over the propodeal dorsum, as opposed to a single transversal row of erect setae restricted to the junction of the propodeal dorsum with declivity, and by a completely black body, whereas the pronotum at least is red in C. kurdistanicus, and the head and mesosoma are always paler than the gaster in C. rebeccae and C. vogti.

Major workers from Israel differ from western Mediterranean specimens by having the dorsum of the mesonotum more convex and distinctly posterior to the level of the propodeum, and by a distinct metanotal groove.

Distribution
Ionescu-Hirsch (2009) - Western Mediterranean and southern Europe to southern Transcaucasus (Radchenko, 1997c), Near East and Iran (Paknia et al., 2008).

Distribution based on Regional Taxon Lists

Taxonomic Notes
Seifert (2019): Camponotus gestroi: This taxon has been described from Sardinia. The type specimen depicted in antweb.org under CASENT0905794 shows a very weak or absent metanotal depression, a convex overall dorsal profile line of mesosoma, and the angle between the dorsal plane and declivity of propodeum is about 120°.

Seifert (2019): Camponotus gestroi creticus: This taxon has been described from Crete. The type specimen depicted in antweb.org under CASENT0910430 shows a very weak or absent metanotal depression, a convex overall dorsal profile line of mesosoma, and the angle between the dorsal plane and declivity of propodeum is about 120°. A synonymy with C. gestroi appears reasonable at the first impression.
