Aglycyderini are a tribe of belids, primitive weevils of the family Belidae. Like in other belids, their antennae are straight, not elbowed as in the true weevils (Curculionidae). They occur only on the Pacific Islands and in the Macaronesian region.
The Aglycyderini have several highly distinctive characters as adults: The rostrum of adult Aglycyderini is very short compared to the average belid and attaches exactly symmetrically at the tip of the head; at first glance, do not look "snouted" but merely somewhat long-headed. Viewed in profile, the head is flat-sided and almost triangular in males, and somewhat swollen and rounded in females. The prementum is large and prevents the maxillae from being seen from below. The sternite of the mesothorax is slightly and extends to between the midlegs in a smooth inward curve. That tarsus, lacking the first segment, is pseudotrimerous. The outer edges of the second tarsal segment are rounded. In females, the ninth tergite is changed into a thin membrane. Intestinally, they show well-developed proventricular blades with sharp external ridges, and a hindgut with rectal loop.
