The was originally described from South America and has been documented undergoing northward range expansion into the southern United States. As a member of Anthicidae, it is likely associated with vegetation and decaying plant material, though specific ecological details remain poorly documented.

Identification

Identification to level requires examination of subtle morphological characters, as Acanthinus species are generally small, slender, and -like in appearance. Members of the Acanthinus can be distinguished from other Anthicidae by the presence of a distinct spine or on the pronotum. Distinguishing A. argentinus from requires detailed examination of antennal structure, pronotal shape, and male genitalia; specific diagnostic characters for this species have not been summarized in widely accessible literature.

Taxonomic note

The specific epithet 'argentinus' refers to Argentina, the type locality. The was described by Maurice Pic, a prolific French entomologist who described numerous species in the early 20th century.

Range expansion significance

The documented northward expansion into the United States may represent natural , human-mediated transport, or previously undocumented native presence. The mechanism of this expansion has not been investigated in published literature.
