Cardiocondyla persiana

Cardiocondyla persiana seems to be restricted to the Near East where it is a rather abundant species (Seifert, 2003). Pashaei Rad et al. (2018) found this species in Iran under a tree in a low rainfall forest.

Identification
Seifert (2003) - A member of the Cardiocondyla bulgarica group. The C. persiana worker differs from the heterogeneous Cardiocondyla sahlbergi and Cardiocondyla bulgarica cluster in particular by larger pubescence length, shorter head, and more developed microsculpture. Cardiocondyla persiana has larger, more strongly demarcated foveolae on vertex with a more pronounced inner corona and interspaces much narrower than foveolar diameter. The promesonotum usually shows in addition to the foveolae a fine longitudinal rugosity (that is in C. sahlbergi and C. bulgarica usually absent or weaker).

The separation of the gyne is probably more difficult. Most similar is C. sahlbergi from which C. persiana can be separated by the larger maximum length of lateral prescutellar lobe and larger ML/CS. The maximum sagittal extension of the lateral prescutellar lobe is 10.9 % of ML in the C. persiana gyne and 8.54 - 9.51 % in 8 gynes of C. sahlhergi. The colour pattern is possibly diagnostic in discriminations against both C. sahlbergi and C. bulgarica.

Taxonomic Notes
Pashaei Rad et al. (2018): Type location Iran, Fars and Shiraz, purported type specimen CASENT0919736 but it is substantially smaller (ca 80%) than that in Seifert’s drawing (assuming the scales are correct) and lacks the head sculpture, etc. The Torabi specimen reported here is an exact match for the drawn specimen.

Worker
Head relatively short, CL/CW 1.158. Postocular index large, PoOc/CL 0.441. Eye relatively small, EYE 0.235. Pubescence length large, PLG/CS 6.83 ± 0.27 %. Vertex with densely-packed, well-demarcated foveolae with strong inner corona; interspaces much smaller than foveolar diameter. Median and paramedian clypeus and small stripe on median vertex smooth; lateral area of clypeus and frontal laminae usually shining and finely longitudinally carinulate. By more developed foveolae and carinulae mesosoma in overall impression less shining than in Cardiocondyla sahlbergi and Cardiocondyla bulgarica. Metanotal groove deep. Anterior margin of postpetiole in dorsal view concave. Petiole rather narrow, its node slightly wider than long. Postpetiolar sternite with weak anteromedian bulge. Dorsal head often bicoloured: anterior head back to level of antennal socket dirty yellowish, remaining vertex dark dirty brown. Mesosoma usually dirty yellowish brown to dirty brown. Waist, gaster, hind- and midfemora often blackish brown. This colour pattern typical, but not consistent throughout the population.

Queen
Head relatively short, CL/CW 1.161. Postocular index rather large, PoOc/CL 0.431. Vertex with densely packed, well-demarcated, clearly bicoronate foveolae of 18 - 19 11m diameter, interspaces much smaller than foveolar diameter. Lateral and caudal area of clypeus and frontal lobes longitudinally carinulate-rugulose. Mesonotum, praescutellum, and scutellum shining but with well-developed foveolae of 18 - 20 mm diameter. Propodeum shining. Lateral metapleuron longitudinally rugulose. Petiole with caudomediodorsal corner. Postpetiole with anteromedioventral corner, its anterior margin in dorsal view concave. Pubescence long and profuse, on first gaster tergite and postpetiole semierect (30 - 45°). Specimen showing a possibly diagnostic colour pattern: dorsal head posterior of antennal sockets dark yellowish brown, anterior of the antennal sockets light-yellowish brown; mesosoma and petiole yellowish brown; femora, postpetiole, and gaster dark to blackish brown.
