Aphaenogaster muschtaidica Emery, 1908 |
A nest was located in dry, sandy soil, below a medium size rock. It was situated on the slope of a small hill, overgrown by pine trees. Workers were surrounding gynes or trying to hide in the soil. Males were hiding below soil heaps. Other ant species collected at the site were: Camponotus piceus, Cataglyphis nigripes, Crematogaster schmidti, Dolichoderus quadripunctatus, Formica clara, Lasius turcicus, Lepisiota cf. frauenfeldi, Messor cf. structor, Pheidole koshewnikovi, Plagiolepis pallescens, Ponera coarctata, Solenopsis cf. fugax, Tetramorium cf. caespitum. Ruzsky (1905) reported a nest located below a tree, in the shady part of Mushthaid Garden. Workers were also collected on the path at the same locality. (Salata and Borowiec 2018)
Identification
A member of the Aphaenogaster gibbosa-group.

Distribution
Salata and Borowiec (2018) – Most recent data confirms its presence in Tbilisi town in Georgia. Nevertheless, Aphaenogaster gibbosa was recorded in few other Georgian localities (Gratiashvili & Barjadze 2008). Most probably however, these records might represent collections of A. muschtaidica. This species was also reported from Azerbaijan (Arnol’di 1948). Records of A. gibbosa from Armenia (Arakelian 1994) can also refer to this species. Therefore, its distribution is probably limited to the Transcaucasian region but requires a more detailed study.
