Sculptotheca puberula

The small size (1.5–2 mm) and eastern North American distribution help distinguish this species from larger anobiids and from western North American Sculptotheca species. Definitive identification requires examination of genitalic characters and detailed sculpturing patterns on the pronotum and elytra, which are diagnostic at the species level within this genus.

Adults measure 1.5–2 mm in length. As a member of Ptinidae, the species likely exhibits the compact, somewhat cylindrical body form typical of small wood-boring beetles in this family, with a pronotum that may have sculptured or tuberculate surfaces reflecting the genus name 'Sculptotheca'.

Eastern North America, including Canada (Nova Scotia, Ontario, Québec) and the United States. GBIF records confirm presence in these Canadian provinces with broader distribution across the eastern United States.

• Sculptotheca hirsutaAnother small North American Sculptotheca species; requires detailed examination of pronotal sculpturing and setation patterns for separation
• Other Ptinidae genera (e.g., Lasioderma, Nicobium)Similar small size and wood-associated habits; Sculptotheca is distinguished by characteristic pronotal sculpturing and antennal structure
