Camponotus sanctus

Pashaei Rad et al. (2018) found this species in Iran on the ground in areas with at least moderate rainfall.

Identification
Ionescu-Hirsch (2009) - C. sanctus is a large species of Tanaemyrmex with broad head, moderate ground sculpture (the major worker is mostly shiny), and prismatic hind tibia ventrally with a row of bristles.

The C. sanctus worker is similar to Camponotus oasium syntypes in size and color pattern, but differs from them by its smaller eye, distinctly shorter mesosoma, scape and legs; generally larger and more abundant punctures on gena; feebler ground sculpture; presence of erect setae on ventral head surface; and more abundant pilosity (mesosoma dorsum with 12–14 erect setae in C. sanctus, as opposed to 9–10 in C. oasium). One to four erect setae on the ventral surface of the head were found in all syntypes of C. sanctus, Camponotus maculatus thoracicus sanctoides Forel and ''Camponotus compressus sanctus var. confellah Santschi, and in examined specimens misidentified by Tohmé and Tohmé (2000: 387) as C. oasium'' (“oasium” morph), and in all the examined gyne, as well as in 150 workers from 50 localities. Three specimens from one nest series from Mount Hermon lack such setae. They have relatively large eyes and an infuscate body similar to ''C. compressus sanctus var. confellah''. They are similar to Camponotus oasium ninivae Pisarski from Iraq in habitus, but differ from it by the larger eye, longer scape and leg, less accentuated sculpture of the mesosoma pleura, distinctly more abundant body pilosity, and darker color.

This is a variable species, in which were described five varieties (Santschi, 1939) distinguished by head shape and width, eye length, mesosoma length and height, and body color. However, comparison of a larger sample of specimens from Israel, Lebanon, and Syria, some of them identified in the past as C. sanctus and ''C. compressus sanctus var. sanctoides'', and the respective syntypes, showed variation of these features among and within the nest series.

C. sanctus and C. compressus cosensis Finzi are indistinguishable morphologically, and may be synonyms.

Distribution
Near East (Wheeler and Mann, 1916; Santschi, 1939) to Iran and Afghanistan (Radchenko, 1997b).
