Alocentron attenuatum
(J.B. Smith, 1884)
Alocentron attenuatum is a of in the Brentidae ( Apioninae). The species is known from scattered records across southern Canada. Like other members of its , it is likely associated with herbaceous vegetation, though specific relationships remain undocumented. The species name 'attenuatum' refers to the slender, attenuated body form characteristic of this .

Identification
Distinguished from other Alocentron by its more attenuated, slender body proportions. The straight rostrum separates it from true weevils (Curculionidae) which have geniculate (elbowed) and usually a more curved rostrum. Accurate identification to species level likely requires examination of genitalia or other fine morphological details by a .
Appearance
Elongate, slender body with a straight, cylindrical rostrum (snout) typical of brentid weevils. The epithet 'attenuatum' denotes the noticeably narrowed or tapering form of the body. arise near the middle of the rostrum. Body size and coloration details are poorly documented in available literature.
Habitat
Specific requirements are undocumented. Based on distribution records, occurs in temperate regions of southern Canada, likely in association with herbaceous vegetation in open or semi-open environments.
Distribution
Recorded from five Canadian provinces: Alberta, British Columbia, Manitoba, Ontario, and Quebec. No records from the United States or other countries have been documented in available databases.
