Genus Hybomitra
Explanation of Names
Hybomitra Enderlein 1922
60 spp. in our area(1), ~twice as many in the Old World
10-20 mm(2)
key to 40 spp. found in e. Canada(2)
holarctic & Afrotropical(3)
Genus 5 (of 6) in the Tribe: Tabanini (which is Tribe 3 of the Subfamily: Tabaninae).
Members of the genus range from small to large (10-20 mm)and are similar to, and not immediately easy to separate from, members of the genus Tabanus. Head characters are the main method to distinguish between these two genera.
The 55 species are mostly northern, Canada and Alaska; being replaced in the remaining USA by Tabanus.
I had the honour with my colleauge Dr. Herb Teskey of naming a new species after Dr. L.L. Pechuman one of the 'greats' of Nearctic Tabanidae: Hybomitra pechumani Teskey & Thomas, 1979. (Comment by Tony Thomas)
