Aulacopone Arnol’di

Type Species: Aulacopone relicta Arnol'di

Diagnosis (Queens): Ants of comparatively medium size. Mandibles subfalcate. Median portion of clypeus modified, raised as a short, blunt triangular point projecting from the antennal insertions to the mandible. Frontal lobe expanded, extending from the clypeal posterior margin to the vertex. Antennal scrobe wide and deep.

Species: relicta.

Distribution: The only known specimens were collected in Azerbaijan in mountainous forests.

Notes: The genus is only known from two queens collected in Azerbaijan. The first specimen was collected in 1929 in Alazapin on the border with Iran, and later designated as the holotype by Arnol’di and deposited at the Zoological Institute of the Russian Academy of Sciences. The second specimen was collected in 1936, also by Arnol’di in the same country, in the region of Khachmaz, and later deposited in his personal collection at the Institute of Evolutionary Animal Morphology in Moscow. However, the holotype has been missing since 1979 and has not been examined for any study other than the original description. The second specimen was coated in gold-palladium for the study of its external morphology using scanning electron microscopy by Taylor (1980).
