Distribution.

Origin. Palaearctic (adventive in North America). Canada: MB, ON [new record]. USA: CT, MA, ME, NH, NY, PA, RI, SC, VT, WI.

Diagnosis.

Males of this species are easily recognized among other Canadian Philhygra by the simple, non-projecting median lobe in lateral view (Fig. 34B View Figure 34 ).

Bionomics.

Most specimens of this species were collected by passive traps in a variety of habitats. In Sweden, P. palustris is considered a eurytopic species that occurs in various types of decaying plant matter, including compost, seaweed and hay piles, and along muddy shores of water bodies ( Palm 1970). It can be collected in very large numbers using a car net (V. Assing, pers. comm.).

Comments.

Philhygra palustris is a Palaearctic species that has become adventive and widespread in eastern North America. In the Palaearctic, it is very broadly distributed and reported from Europe, North Africa (Morocco), Russia (European and Siberia), Mongolia, North and South Korea (Lee and Ahn 2012), Japan, and northern China ( Newton 2019). It is also known from the Azores and the Canaries ( Newton 2019), though it is likely introduced there as well.

This species was reported from Canada (Manitoba) for the first time in the checklist by Bousquet et al. (2013) but no specimens could be found in the CNC to support this record. It is likely that the species P. tenuicula (Casey, 1911) described from Manitoba and treated as a synonym of P. palustris ( Newton 2019), is the basis of this record. Philhygra palustris was first recorded from North America by Muona (1984) from New York, Maine and Pennsylvania but detailed specimen level data were not provided. Several specimens from various localities in southern Ontario have been sequenced, and their barcodes cluster with European specimens, with multiple haplotypes shared between Canada and Europe. This common European species is here confirmed to be adventive in Canada and is probably broadly distributed in at least eastern North America.
