Subfamily Pherhombinae Kasparyan, 1988

This is a monotypic and extinct subfamily, it includes the only genus Pherhombus Kasparyan, 1988 . According to the latest revision ( Manukyan, 2019), the fauna of Baltic amber contains six species: P. antennalis Kasparyan, 1988 , P. brischkei Brues, 1923 , P. dolini Tolkanitz & Narolsky, 2005 , P. kasparyani Manukyan, 2019 , P. krextepellensis Manukyan, 2019 , and P. sorgenauensis Manukyan, 2019 . The biology of pherhombines was reconstructed based on the structure of the mandibles, ovipositor, metasoma, claws and other parts of the body. They most probably developed as parasites of openly living insect larvae. Active nuptial flight took place in spring, probably in the twilight or night hours. Their females mainly inhabited the humid lower shrub-herbaceous layer of the “amber forest”, where the hosts also lived ( Manukyan, 2019).
