Identification
Members of Brachyceridae can be distinguished from other weevil by genitalic and other morphological characters that have historically supported its separation from Curculionidae. Some within the family, such as Absoloniella, are characterized by extreme morphological reduction including blindness and winglessness. Specific identification criteria require examination of male genitalia and other fine structural features.

Taxonomic History
Brachyceridae has undergone significant taxonomic revision. It was historically treated as the Brachycerinae within Curculionidae, and has also been placed within Erirhinidae in some classifications. Current treatments recognize it as a distinct within Curculionoidea, though relationships among weevil families remain under study.
Notable Genera
Absoloniella is a well-studied within Brachyceridae, containing five blind, wingless Mediterranean : A. reitteri, A. italica, A. pacei, A. servadeii, and A. nitidipennis. A century-long taxonomic ambiguity involving this genus was resolved in 2014 through neotype designation.
