Two words
Hi Stephen,

I didn´t want to propose this BEING Cis boleti - I just suggested it may belong in the same species group.

In most Cis spp., the outer corner (I wronly said: edge) of anteriour tibiae is sharply angulate to dent-like produced. A few Cis spp. (but not those from C.boleti-group) have the tibia apically bluntly rounded.

Hi Stephen,

this is a Ciid - though a "big" one for its family. It resembles much the palearctic species Cis boleti (large size, unequal puncturation on elytra, short, a little scaly pubescence, expanded lateral sides of pronotum) -
so I guess it´s safe to name it: Cis sp.
(to make sure, check, if anterior external edge of protibia is tooth-like produced, and protibia with no other remarcable features)

cheers, Boris

Cis species
I actually have second thoughts about the identity of this beetle. Other than the tibial spurs, the protibia appears to be unremarkable, but its anterior external edge appears to be smooth and without tooth-like projections. Does this match up with a Cis??
Anyway, Cis boleti is not listed among Canadian Cis. According to J.McNamara in this article, the Cis species listed for Ontario include:

C. americanus Mannerheim
C. casteli (Dury)
C. creberrimus Mellié
C. fuscipes Mellié
C. horridulus Casey
C. levettei (Casey)
C. pistorius Casey
C. striolatus Casey

Yes, if this is a Cis, it does seem safer to leave it at genus level.
