Comments.

Dirrhagofarsus ernae was recently described from OH, in the USA and occurs from NH, west to WI, south to MO, AL and VA ( Otto et al. (2014). According to Otto et al. (2014), the sudden appearance of this species in the USA suggests that it may be an introduction to North America, possibly a previously unknown species from Asia. In NB, no specimens were encountered prior to 2013 despite intensive sampling with Lindgren funnel traps at many sites, including Odell Park, where it was first encountered during 2013. It is possible that Dirrhagofarsus ernae is a recent arrival to NB.
