Redescription of the larvae of Bruchidius atrolineatus (Pic) (Coleoptera: Bruchidae: Bruchinae)

The morphology of final and first instars of the larvae of Bruchidius atrolineatus (Pic) is illustrated and described. Structures described for final instar include enface view, antenna, clypeolabrum, epipharynx, mandible, maxilla, labium, spiracle, and leg. First instar structures described include head capsule, frons, gena, clypeolabrum, mandible, antenna, prothoracic plate, prothoracic chaetotaxy, spiracles, legs, and abdominal chaetotaxy. The clypeolabrum, antenna, and leg of the final instar, as well as the leg and prothoracic plate of the first instar are redescribed. Significant characters are indicated for final and first instar larvae. Relationships between this species and others within the subfamily Bruchinae based on larval characteristics are discussed.
