Tabanidae of Canada, east of the Rocky Mountains 1: a ...

Chrysops luteopennis Philip
Length 8mm. A very rare species known from only 5 localities, including 3 Canadian
localities (both in Ontario). Teskey (1990) described wing cell br as fully pigmented and
keyed this species on this basis. However, Teskey’s (1990) wing photo shows cell br with
only about the basal one-third infuscated as does the wing image in Pechuman et al.
(1983). A combination of the pale wing pattern, discal cell only half infuscated and body
pattern does allow for recognition of this species.
