Bionomic Notes. Adults were collected from the nests of a black Formica species of mound building ant. Some adults were collected by sifting soil from the top layer of the nest, including the holotype and paratypes ( Assing 2007). However, the most efficient method for collecting adults of this species was to place small boards on the ant nests and examine the underside of the boards on subsequent days. Adults would be found resting on the underside of the boards. Adults were collected during April, May and September. Th is species probably overwinters in the adult stage. Collection method: sifting top layer of a nest, examining underside of boards placed on a nest.

Distribution in Canada and Alaska. NB ( Assing 2007). Additional specimens were collected from ants at other sites near the type locality and near Tracy, New Brunswick. Th is species may be more widespread than the records indicate.

Comments. The female of A. formicina was unknown at the time of the description ( Assing 2007) and the female spermatheca, tergite and sternite 8 are illustrated for the first time in Figures 58–60. Externally the female is identical to the male. The spermatheca of A. formicina is similar in shape to that of A. inquilina , but is significantly larger.
