Taxonomy
The species name was originally published as Ptinus globulum by Solier in 1849, under the "section" (equivalent to a subgenus) he named therein as Trigonogenius. Numerous subsequent authors have historically misspelled the name as globulus, though some sources still use the correct spelling (e.g., ). Solier, in the same work, named a variety of this species as "var. α globosus", which has only added to confusion surrounding the correct spelling (e.g., ), and other sources treat globosus as a subspecies of globulum (e.g., ).
