return to listIran list {link to the Hymenoptera Name Server} Type location Algeria (Formica rufotestacea, Foerster, 1850b: 489, worker; Messor rufotestaceus Foerst., Emery, 1908e: 439, illustrated full description, major & minor workers & queen; Forel, 1910a: male) - no type images on Antweb (June 2015)

thoracica (Atta thoracica n. sp. Mayr, 1862: 742, illustrated, worker) from Syria - no images on Antweb (June 2015)
gracilinodis (Aphaenogaster gracilinodis n. sp., Emery, 1878b: 55, worker) from Syria - no images on Antweb (June 2015)

Perhaps not a Messor at all but as Emery (1875) had, an Aphaenogaster.

{Messor rufotestaceous} {Messor rufotestaceous antenna}Foerster's (1850b) description is at {original description}. Emery (1908e) gave an illustrated (antenna) full description, this is at {original description}. Mayr's (1862) gave a description of thoracicus is at {original description}. Emery's (1878b) description of gracilinodis is at {original description}. Mohamed et al (2001) noted the underside of the head has only moderately curved and straight hairs.

Mayr's thoracicus illustration shows short sharp propodeal teeth; Emery (1908e) wrote of "stumpfen zahnen" = blunt teeth. Thome & Thome (1981b) showed merely angles at the dorsum and declivity junction.

Cagniant (1996a) in his key leads to two species which are essentially yellow-orange, have slender antennae and smooth gasters. One, Aphaenogaster foreli has propodeal spines, the other, which he gave as A. leveillei has no spines.  He noted the latter also as being synonymous with A. pallida laurenti of Santschi (1939d: 69). Significantly both were described from Algeria and appear to match Foerster's description. The Syria locations were added by Emery (1908) who also gave the dimorphism, something that Cagniant appears not to have seen in North African specimens.

Note: The difference and geographical distance between the Algeria type and the Syria-Iran forms suggests that two distinct species may be involved.  In the absence of type images it is impossible to resolve.
