Paradonus pectoralis
(Say, 1834)
Large-chested Click Beetle
Paradonus pectoralis is a click beetle in the Elateridae, originally described by Say in 1834. The species was previously classified under the Tetraonyx as Tetraonyx pectoralis. It is known from multiple Canadian provinces including Alberta, British Columbia, Manitoba, New Brunswick, and Nova Scotia. The "Large-chested Click Beetle" reflects a distinctive morphological feature of this species. Like other click beetles, it possesses the characteristic prosternal process that enables the "clicking" mechanism for righting itself when overturned.

Taxonomic History
This was previously placed in the Tetraonyx, as evidenced by museum holdings still listed under Tetraonyx pectoralis Haag-R. It has since been transferred to the genus Paradonus, reflecting ongoing taxonomic revisions within the Elateridae.
Data Limitations
Detailed biological information for this appears sparse in the available literature. The 14 iNaturalist observations and limited museum records suggest it may be infrequently encountered or underreported, or that it occupies with limited human activity.
