Pseudopomyzidae

The family Pseudopomyzidae comprises minute to small (1.7–5.5 mm), dark-coloured acalyptrate flies; formerly they have been treated as a subfamily of Cypselosomatidae

==Biology== The biology of pseudopomyzines is very poorly known. Most species are from the New World and Asia. There is only one European species, Pseudopomyza atrimana (Meigen, 1830), which occurs in woodland, and adults have been found to gathering over rotting logs or attracted to the freshly cut and sappy stumps or logs of deciduous trees.
