A nest was found under a stone in deciduous mountain forest at an altitude of 514 m. (Borowiec and Salata 2022)
Identification
Ionescu-Hirsch (2009) - C. sannini paratypes are hardly distinguishable from Camponotus aethiops in having a straight propodeal dorsum, as opposed to a variable propodeal dorsum, scape and tibiae with decumbent pubescence, as opposed to apressed, and dark brown mesosoma with very superficial lateral striation, as opposed to a generally darker and matte mesosoma in major workers of C. aethiops. However, specimens from Beirut have a distinctly concave propodeum and scape with apressed pubescence. Furthermore, in the original description of C. sannini completely black nest series are also mentioned.

Description
Worker
Ionescu-Hirsch (2009) - TL = 6.9–9.4, HL = 1.95–2.42, HW = 1.80–2.34, EL = 0.47–0.48, SL = 1.70–1.88, ML = 2.54–3.05, PW = 1.29–1.52, mTbL = 1.47–1.60, hTbL = 1.91–2.19 (n = 10).
Borowiec and Salata (2022) - Moderately large to large, polymorphic; minor workers HL: 1.194-1.317 (mean 1.247); HW: 0.838-0.960 (mean 0.888); SL: 1.321-1.444 (mean 1.386); EL: 0.341- 0.373 (mean 0.352); ML: 1.92-2.05; MW: 0.78-0.86. Color. Body predominantly brown, mandibles anterior margin of clypeus and gena yellow to yellowish brown, in some specimens mesosoma slightly paler brown than head and gaster, sometimes pronotum yellowish brown and rest of mesosoma pale brown, gaster with yellowish posterior margin; antennae completely yellow to pale brown, legs usually completely yellow or coxa and femora at base indistinctly infuscated by brown. Head. Elongate, 1.3-1.4 times as long as wide, sides in front of eyes straight and parallel, behind eyes regularly softly rounded, posterior margin rounded or in the middle straight. Clypeus pentagonal, in the middle forms rectangular plate protruding anterad, its anterior margin straight, slightly crenulate, on sides anterior clypeal margin deeply emarginate, sides of clypeus strongly converging posterad, straight, posterior margin straight but in the middle shallowly emarginate by frontal triangle, clypeal plate along middle with distinct obtuse keel, whole surface with microreticulation, surface shiny, covered with very sparse and short appressed hairs, anterior margin in the middle with 6 very long setae, on sides with few short additional setae, central plate with several moderately long to long erected setae. Head microreticulate, sculpture in posterior half and sides of head often tends to form transverse or circular striation, on sides of head and in occipital area microsculpture indistinctly diffused, background shiny, covered with sparse and short appressed pubescence, appears partly unhaired, whole surface including gena, sides of head and occipitum with numerous moderately long to long erected setae, ventral side of head with less than 10 moderately long to long erected setae. Scape very elongate, thin, 1.5-1.6 times as long as width of head, slightly, regularly widened from base to apex, its surface microreticulate, slightly dull, with short and sparse appressed pubescence. Funicular segments elongate, thin, first segment approximately 2.7 times as long as wide and 1.4-1.5 times as long as second segment, third segment distinctly longer than second, the rest of funicular segments very elongate. Eyes large, elongate oval, 0.28 length of head. Mandibles stout, diffusely microreticulate and punctate, surface shiny. Mesosoma. Elongate, 2.4-2.5 times as long as wide, dorsally and laterally distinctly sculptured tending to form longitudinal and oblique striation, surface strongly shiny. In lateral view dorsum form regular arch, without mesonotal groove, propodeum never with shallow concavity, posterior face forms with dorsum obtuse angle. Surface of mesosomal dorsum with short and scarce, hardly visible depressed hairs, lateral sides partly unhaired, pronotum with 3-6, mesonotum 2-3, propodeum 3-5 very long erected setae, number of erected setae increases with the size of the ant. Waist and gaster. Petiole in form of broad, thin scale with convex anterior and flat posterior face, apex regularly rounded; surface with distinct transverse striation covered with short and sparse appressed hairs, apical crest with 4-6 very long erected setae. Gaster shorter than mesosoma, tergites with fine transverse microstriation, interspaces without additional microsculpture thus surface of gaster appears strongly shiny, covered with short and scarce appressed hairs; all tergites with 3-6 very long erected setae centrally and a row of long setae on posterior margin, row of short setae on posterior margin moderately elongate, reaching 2/3-3/4 length of the transparent margin, never to the posterior margin of tergite. Legs. Moderately long and thin, hind femora shorter than mesosoma, surface of legs covered with sparse appressed to slightly decumbent hairs, inner margin of tibiae in apical half-length with row of thorns. Ventral surface of fore femora with 3-5 long erected setae.
Major workers: HL: 1.910-2.343 (mean 2.113); HW: 1.612-2.303 (mean 1.967); SL: 1.750-1.958 (mean 1.871); EL: 0.427-0.492 (mean 0.456); ML: 2.64-3.07; MW: 1.25-1.49. In body color and sculpture similar to minor workers but antennal scape often rusty yellow and head appears less shiny than in minor workers. Head stouter, approximately as long as wide, widest in basal ¼ length, sides softly rounded and converging anterad, posterior margin concave; anterior margin of clypeus distinctly crenulate, central plate of clypeus head with more numerous erected setae, gular area with more than 15 short to long erected setae. Scape proportionally shorter, 0.9-1.2 times as long as width of head. Eyes proportionally smaller, 0.22 length of head; mesosoma stouter, 2.1-2.3 times as long as wide, in profile forming more convex arch, propodeum with less obtusely posterior angle. Setation of all mesosomal parts more numerous, pronotum often with more than 10 setae. Ventral surface of fore femora with 5-7 long erected setae.
Taxonomic Notes
Ionescu-Hirsch (2009) - The original description of C. sannini (Tohmé and Tohmé, 1999) refers to Bernard’s (1968) redescription of C. aethiops, in which he mentioned the matte head and black color of C. aethiops specimens from France (Bernard, 1968). However, C. aethiops in its current concept is a variable species, so that the diagnostic characters of C. sannini are weak. A further study of these species from their entire distribution area will clarify the affinities between the Israeli and other specimens.
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).
