Tachysphex pompiliformis
Tachysphex pompiliformis is a small digger wasp in the family Crabronidae. The species was taxonomically redefined in 2016 when Straka demonstrated that the name had been misapplied to at least 14 similar species in Europe and Turkey. Four former synonyms were restored to species status: T. austriacus, T. dimidiatus, T. jokischianus, and T. nigripennis. As a result of this revision, the precise distribution and biological details of the true T. pompiliformis remain uncertain pending review of voucher specimens. The species belongs to the pompiliformis species-group, the most species-rich group within Tachysphex in Iran.
