Rhyssomatus aequalis Horn, 1873, first records for Quebec with detailed locality information

Species identification confirmed by RSA, 2015

Note.

This native species was known in Canada only from Ontario (McNamara 1991) until Bousquet et al. (2013) recorded it from Quebec without providing any specific details about its distribution within the province. Before the recent addition of a few specimens from the series reported herein, the CNCI contained 33 specimens from Canada, all collected by W.J. Brown in extreme southern Ontario between 1931 and 1940, 17 of them on " Convolvulus sepium pubescens " (hedge false bindweed, now known as Calystegia sepium (L.) R. Br. ( Convolvulaceae)). Based on these label data and on those of most specimens reported henceforth, R. aequalis appears to be associated with C. sepium .
