Estheria
Estheria is a genus of tachinid flies in the family Tachinidae, established by Robineau-Desvoidy in 1830. The genus contains 18 recognized species distributed across the East Palearctic and Oriental regions, including western China, Nepal, Pakistan, Malaysia, and Vietnam. Four species were described as new to science in 2019: E. hirtinerva, E. prostata, E. tibetensis, and E. wangi. As members of Tachinidae, these flies are presumed to be parasitoids, though specific host associations for Estheria species remain undocumented in the available literature.
