Goniops
Goniops is a monotypic genus of horse flies in the family Tabanidae, containing the single species Goniops chrysocoma. The genus was established by Aldrich in 1892 and is classified in the subfamily Pangoniinae and tribe Goniopsini. It is endemic to North America.
Pangoniini
horse flies
Pangoniini is a tribe of horse flies (Tabanidae) within the subfamily Pangoniinae, containing some of the most morphologically primitive members of the family. Species exhibit diverse feeding strategies: some females are haematophagous (blood-feeding) while males and certain species are nectarophagous (nectar-feeding), as determined by mouthpart morphology. The tribe shows progressive evolutionary reduction in female mandibles and structural modifications of antennal and tibial characters. Australian members are predominantly low-flying insects that do not suck blood, contrasting with Chilean species that include both blood-feeding and non-blood-feeding forms.

Silvius jeanae is a species of horse fly in the family Tabanidae, described by Pechuman in 1960. The genus Silvius belongs to the subfamily Pangoniinae, a group of horse flies characterized by elongated mouthparts adapted for nectar feeding in many species. Like other members of the genus, S. jeanae likely exhibits the slender body form and reduced eye contact typical of Pangoniinae. The species epithet honors an individual named Jeana, following the pattern of several Silvius species named after women.
Stonemyia
Stonemyia is a genus of horse flies in the family Tabanidae, established by Brennan in 1935. The genus contains approximately twelve described species distributed across North America, Europe, and Asia. Species within this genus are known to visit flowers for nectar feeding.
Stonemyia californica
Stonemyia californica is a species of horse fly in the family Tabanidae, first described by Bigot in 1892. The species is distributed across western North America, with records from Canada, the United States, and Mexico. As a member of the subfamily Pangoniinae, it belongs to a group of flies characterized by elongated mouthparts adapted for nectar feeding rather than blood-feeding.
Stonemyia isabellina
Stonemyia isabellina is a species of horse fly in the family Tabanidae, first described by Wiedemann in 1828. It belongs to the subfamily Pangoniinae and tribe Pangoniini. The species has been documented in the United States, though detailed biological information remains limited.
