Taxonomic Notes



Distribution in Canada: Venables 1914 [BC, as Synhalonia nevadensis (Cresson)].

This species was recorded from British Columbia as Synhalonia nevadensis (Cresson) by Venables (1914: 62). Timberlake (1969) indicated that some of the specimens recorded in the past under this name (and E. intrudens (Cresson)) are likely misidentified, and also reported its distribution ranging as far north as Oregon and Montana. At this time, this species is left as a tentatively valid species in Canada until the material identified by Venebles (1914) can be examined and verified.
