Camponotus lateralis

An arboreal ant, widespread from the Iberian Peninsula to western Anatolia, and in NW Africa (Rigato & Toni, 2011).

Identification
Ionescu-Hirsch (2009) - C. lateralis is characterized by a deep metanotal groove and a flat or concave propodeal dorsum posteriorly. The petiolar scale is strongly convex anterodorsally and flat posteriorly. The body is feebly sculptured and shiny. The pilosity on the dorsum of the propodeum consists of a transversal row of six erect setae at the junction with declivity and short apressed pubescence. C. lateralis has a weak ground sculpture, is mostly shiny, and has yellowish-brown head and mesosoma, occasionally reddish-brown to dark blackish-brown, and black gaster. C. lateralis and Camponotus staryi (its sister species, according to Radchenko, 1997c) are similar, except for the propodeal dorsum being lower than the highest point of the mesonotum in C. lateralis, as opposed to a propodeal dorsum exceeding the highest point of the mesonotum in C. staryi, and a uniformly dark gaster, as opposed to a mostly dark brown gaster with the first segment ochraceous. C. lateralis is similar to Camponotus dalmaticus except for its head being paler than gaster, as opposed to the head equally dark as the gaster. C. lateralis is similar to Camponotus rebeccae in coloration but differs from it by a deep metanotal groove, as opposed to a shallow metanotal groove and by a flat or concave propodeal dorsum, as opposed to a convex propodeal dorsum in C. rebeccae.
