scientific name    Thanatophilus trituberculatus    

identification
This small species is distinct from other Alberta silphines by its shortened outer elytral costa, which does not extend beyond the posterior callus. Also, the lobe of the prothoracic hypomeron is rounded rather than pointed, and without an apical membrane.

range
In North America this Holarctic species occurs from northern Alaska to northern Ontario. In Alberta trituberculatus occurs over the northern half of the province. A record from the southeast needs to be confirmed.

notes
Meaning of name: "marked with 3 tubercles." It refers to the three tubercles near the apex of each elytron, these tubercles marking where the elytra fit over the folded flight wings, with the outer one -- the posterior callus -- at the end of the third costa being the most marked.
