The type specimens of Cardiocondyla littoralis were collected when foraging on the surface of a salty loess soil with very sparse vegetation near the margin of a lake in a semidesert. (Seifert 2003)
Seifert (2003) - A member of the Cardiocondyla bulgarica group. Clearly differed from the syntopic Cardiocondyla ulianini by much larger PoOc/CL, deviating vertex sculpture, larger PEW/PPW, lower petiole with less steep anterior slope, and by shorter spines. Cardiocondyla littoratis is similar to the W Palaearctic Cardiocondyla gallilaeica from which it differs by the much larger PoOc/CL and PEW/PPW, the more excavated dorsofrontal postpetiolar margin, the almost straight median third of occipital margin, and the less narrow frons with more curved frontal carinae.

Similar to Cardiocondyla gallilaeica. Head moderately elongated (CL/CW 1.167); occiput in dorsal aspect with evenly rounded corners, median third straight or weakly concave. Postocular distance much larger than in C. gallilaeica sp.n. (PoOc/CL 0.442). Eye rather large (EYE 0.249). Clypeus between level of the paramedian 1st order setae smooth, its anteromedian margin straight or weakly concave. Frontal laminae and small area posterior ofthem finely and densely longitudinally rugulose. Vertex completely without longitudinal microsculpture, in overall impression similar to situation in C. ulianini, but foveolae frequently bicoronate and with clearly defined circular margins, foveolar interspaces glabrous and on average narrower than foveolar diameter (dFOV 13 - 16). Anteromedian area of vertex glabrous. Frontal carinae immediately caudad from FRS level slightly converging, frontad incurving. Frons less narrow than in C. gallilaeica, FRS/CS 0.241. Dorsal area of mesosoma in overall impression shining; dorsal area of promesonotum with shallow foveolae of 9 - 16 mm diameter, interspaces clearly wider than foveolar diameter; dorsal area of propodeum shining but very finely microrugulose-reticulate. Caudolateral area of pronotum, ventrolateral area of mesonotum, mesopleuron, and propodeum below spiracular level reticulate. Metapleuron laterally with 2 - 4 curved longitudinal carinae. Outer spine base distance very small, SPBA/CS 0.223; spines sharp but on average shorter than in Cardiocondyla ulianini, SP/CS 0.087. Metanotal depression rather deep (MGr/CS 3.7 %). Waist segments almost smooth and shining. Petiole very narrow (PEW/CS 0.274), its frontodorsal profile less concave, more directed caudad, and the node lower than in C. ulianini; node in dorsal aspect as long as wide, tapering frontad. Postpetiole in dorsal aspect about 1.7x as wide as median length, less than 2x as wide as petiole (PPW/PEW 1.825), and with strongly concave anterior margin; postpetiolar sternite with shallow anteromedian bulge. Colour of head, mesosoma, femora, and gaster dark brown; waist segments sometimes slightly lighter, with yellowish tinge.
