Chrysotachina
Chrysotachina is a genus of tachinid flies (Diptera: Tachinidae) established by Brauer & Bergenstamm in 1889. The genus comprises approximately 22 described species distributed primarily in the Neotropical region. Species within this genus are parasitoids, with larvae developing inside other insects. The genus is placed in the tribe Polideini within the subfamily Tachininae.
Exoristoides
Exoristoides is a genus of tachinid flies described by Coquillett in 1897. The genus contains five recognized species distributed across North America. As members of the tribe Polideini, these flies are parasitoids, though specific host associations remain poorly documented for most species.
Homalactia
Homalactia is a genus of tachinid flies (family Tachinidae) described by Townsend in 1915. The genus contains at least one described species, H. harringtoni, originally described by Coquillett in 1902. Tachinid flies in this group are parasitoids, though specific host relationships for Homalactia remain poorly documented. The genus occurs in northern North America.
Lydina
Lydina is a genus of tachinid flies established by Robineau-Desvoidy in 1830. The genus contains six recognized species distributed across the Holarctic region, including Europe, North America, and East Asia. Members of this genus are parasitoid flies, a characteristic trait of the family Tachinidae.
