Camponotus aethiops

Widespread in southern Europe and Turkey, especially in Mediterranean habitats (Rigato & Toni, 2011).

Identification
Ionescu-Hirsch (2009) - C. aethiops is a member of the subgenus Tanaemyrmex, recognized by its small size, the head with erect setae on the genae and ventral surface, the tibiae slightly compressed laterally and without a dorsomedial ridge, covered only with apressed pubescence in addition to a ventral row of bristles, and its black to reddish-black body. Major workers have matte head and mesosoma dorsum.

Several varieties of C. aethiops were described based on color, shape of the propodeum, and strength of their sculpture (see Emery, 1908). The Israeli specimens show a variability in these features that encompasses all Eastern Mediterranean forms of C. aethiops, although these features are not “correlated”, as stated in the original description. Workers in one series are similar to syntypes of var. concava Forel (Kugler, personal communication) because of their distinctly concave propodeal dorsum in lateral view and black body with reddish legs. However, in other series, the propodeal shape and color differ: the propodeal dorsum in lateral view varies from distinctly concave to straight, and the body color varies from completely black, to partly black with head and mesosoma dark brown; while the legs range from black to ferruginous-brown or brownish-yellow.

Distribution
Ionescu-Hirsch (2009) - Western Palaearctic, from Germany to Kazakhstan, and the western Mediterranean through southern Europe and Asia Minor to Afghanistan (Radchenko, 1997b) and Israel.

Determination Clarifications
The species from Lebanon that was formerly identified as Camponotus concavus Forel (junior synonym of C. aethiops in Bolton et al., 2006) by Tohmé (1969a) was reidentified as Camponotus sannini by Tohmé and Tohmé (1999).
