Natural history.

Adults were collected from Lindgren funnel traps in a jack pine forest (most), a red pine forest, and an old-growth white spruce and balsam fir forest. Specimens were captured during May and June.


Known only from NB, Canada.


We have checked the world literature on the genus and compared all available genital illustrations and found none matching our species, which led to the conclusion that it was undescribed ( Williams 1970a, 1970b, 1972, 1973a, 1973b, 1975, 1976, 1979, Frank 1972, Lohse in Lohse 1974, Frank et al. 1992, Assing 1995, 2003). In addition, we consulted J.H. Frank, who studied American and Caribbean types and species of Oligota  , and he confirmed that our species was not among the species he studied.
