Camponotus dalmaticus

Identification
Ionescu-Hirsch (2009) - According to Radchenko (1997c), C. dalmaticus belongs to the Camponotus piceus complex of the Camponotus lateralis species group, together with Camponotus abrahami, Camponotus figaro, and Camponotus piceus. C. dalmaticus differs from C. abrahami (studied specimens from Lebanon identified by C.A. Collingwood), by the clypeus being incised anteromedially, as opposed to entire, by the presence of a metanotal groove, as opposed to a lack of such, and by a red mesosoma (at least pronotum), as opposed to a completely black mesosoma. It differs from C. figaro and C. piceus by the presence of a single transverse row of erect setae on the junction of the propodeal dorsum with declivity, as opposed to the erect setae scattered all over the propodeal dorsum in the latter species (see also Emery, 1925a). C. dalmaticus has the clypeus incised anteriorly and the arrangement pattern of the propodeal setae similar to Camponotus lateralis and Camponotus rebeccae but it differs from these species in its black head and gaster, whereas C. lateralis and C. rebeccae have the head always paler than the gaster. It further differs from C. rebeccae by its deeply impressed, as opposed to shallow, metanotal groove; a difference especially marked in major workers, by its propodeal dorsum flat or concave posteriorly, as opposed to convex, and by a slightly broader petiolar scale: the ratio of maximum petiolar width to pronotum width = 0.47–0.60 (n = 33), as opposed to 0.41–0.53 (n = 47).
