Author: John F. Lawrence.

Classification

Suborder Polyphaga, Series Cucujiformia, Superfamily Curculionoidea.

Description

Antenae with 7 to 11 segments and a 1 to 4 segments club. Antennal insertions exposed or concealed. Visible portion of procoxa projecting bellow prosternum with the trochantin concealed. Procoxal cavity externally closed and internally closed. Mesocoxae contigous to separated by more than 1 coxal width, with mesocoxal cavity laterally closed. Tarsal formula rarely 5-5-5 or 5-5-5 but tarsomere 4 reduced and concealed at base of lobe on 3 (pseudotetramerous). Number of ventrites 5 or rarely 6 with apparently 0 or with 2 connate. Body length 0.8-40 mm. Body highly variable in form, glabrous to pubescent or squamose. Antennae geniculate. Rostrum usually well-developed, but reduced or absent in several groups; labrum not visible and palps reduced and immovable. Sides of prothorax not margined. Tarsomere 3 usually lobed. Pygidium exposed or concealed.

Quick identification

Curculionidae is a very large family, which are rarely confused with other families, except perhaps members of the Scolytinae and Platypodinae (last three figures) which may resemble some Bostrichidae or Ciidae but differ in having elongate eyes and a geniculate antenna with a solid club.
