The new species is similar to the Holarctic species Acantholeria moscowa Garrett, 1925 in the hind tibia with a poorly developed ventral swelling at middle and a bifurcation on cerci, but can be distinguished from it by the following characteristics: Crossveins r-m and upper edges of dm-m with obvious dark markings on membrane (in A. moscowa, hyaline wings without infuscation); cerci with a bifurcation near base (in A. moscowa, a bifurcation at apex); surstylus gradually narrowed towards apex, broadly rounded at tip (in A. moscowa, not narrowed at middle, almost parallel, extended to apex).</p><p>Etymology. The specific name A. gorodkovi is in honor of Dr. Kirill Borisovich Gorodkov, a distinguished scientist who worked at the Zoological Institute of the Russian Academy of Sciences, in recognition of his outstanding contribution to the taxonomic research of this genus.</p></div>	https://treatment.plazi.org/id/053B87A9B4364801FF5F673410940BF5	Public Domain	No known copyright restrictions apply.
