Having studied some recent Danosoma has made me re-evaluate my initial ID. Thanks for catching Denis!

If so, I wonder if "mine" from a few years back is actually Lacon rather than Danosoma:

could be...
the two can be tough dorsally. The best way to separate them is the presence (Lacon marmoratus) or absence (Danosoma spp.) of tarsal grooves on the hypomeron. Note, the tarsal grooves are not present on ALL Lacon, but they are on marmoratus.

No records of L marmoratus for the Maritimes YET
Not that it is not possible, but to date, there have been no records of L marmoratus for the Canadian Maritimes or even the next-door State of Maine:

AND
2)http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3337055/
