Camponotus baldaccii Emery, 1908 |
Very thermophilous species. Prefers open and sunny habitats, especially pastures with shrubs, stony hills with scarce vegetation and few trees, fryganas, periodic riverbeds, roadsides, limestone gorges but was noted also from pine groves, olive plantations, stream valleys with luminous deciduous or pine forest. Foraging workers were often observed in tourist resorts and villages on fig trees searching for producing honeydew aphids and cocccids. Nests in soil under large stones. Most records are from low and mid altitude below 500 m, the highest locality was from Lefka Ori Mts., Crete at an altitude 1800 m. (Borowiec and Salata 2022)
Identification
Ionescu-Hirsch (2009) - C. baldaccii is a small species of Tanaemyrmex, with hindtibia flattened but without a distinct dorsomedial ridge, and with a ventral row of bristles. It has abundant erect setae on the ventral head surface but lacks such setae on the genae. The ground sculpture is feeble and the entire ant is shiny, except for major workers, whose head and mesosoma dorsum are sub-matte. The body of major workers is reddish-yellow, with the head, dorsum of mesosoma, dorsum of first two gaster tergites, and the three posterior-most gaster segments brown. C. baldaccii is similar to Camponotus cecconii differing in the feebler ground sculpture, and with major workers having the head and mesosoma dorsum sub-matte, as opposed to matte in Camponotus cecconii. C. baldaccii is similar to Camponotus sp. near baldaccii, a species misidentified as Camponotus sanctus in Tohmé and Tohmé (2000: 390), in having the hindtibia without a distinct dorsomedial ridge, relatively abundant erect setae on the ventral head surface, and a similar sculpture and color pattern, but differing from it by its distinctly smaller size: HW < 3.3 mm in C. baldaccii (Collingwood and Agosti, 1996) and HW up to 3.8 mm in Camponotus sp. near baldaccii (Tohmé and Tohmé, 2000).

Funicular segments elongate, thin, first segment approximately 3.6 times as long as wide and 1.3-1.4 times as long as second segment, third segment distinctly longer than second, the rest of funicular segments very elongate. Eyes large, elongate oval, 0.25 length of head. Mandibles stout, diffusely microreticulate and punctate, surface shiny. Mesosoma. Elongate 2.5-2.7 times as long as wide, distinctly sculptured tending to form longitudinal, transverse and oblique striation, surface strongly shiny. In lateral view dorsum form regular arch, without mesonotal groove, propodeum never with shallow concavity, posteriorly very broadly rounded. Surface of mesosomal dorsum with short and scarce, hardly visible depressed hairs, laterally surface partly unhaired, pronotum with 2, mesonotum and propodeum with up to two erected setae, number of erected setae only slightly increases with the size of the specimen. Waist and gaster. Petiole in form of broad, very thick 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 two 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; first tergite with a pair of very long erected setae centrally and a row of 4 long setae close to posterior margin, two subsequent tergites with 2-4 long setae in front of the middle and similar row of 4-6 setae close to posterior margin, moderately elongate, appressed hairs on posterior margin of tergites very short, reaching to 1/3-1/2 length of the transparent margin. Legs. Elongate and thin, hind femora only slightly shorter than mesosoma, surface of legs covered with very sparse appressed hairs, inner margin of tibiae in apical 1/3 length with 2-6 thorns.
