Caridae

Definition

A small Gondwanan family of primitive weevils (Coleoptera) characterized by straight (non-geniculate) antennae, antennae inserted on the rostrum in a position not visible from above, absence of spiracles on abdominal tergites 6 and 7, and a prothorax lacking lateral carinae. The family is distinguished from more derived weevil families by these plesiomorphic traits.

Etymology

Example

Caridae species retain straight antennae rather than the elbowed (geniculate) antennae typical of most weevils, a trait shared with other primitive weevil groups such as Nemonychidae and Anthribidae.

Usage Notes

A family of limited geographic distribution, primarily found in Gondwanan regions. The family's placement among primitive weevils is based on multiple morphological symplesiomorphies. A proposal to synonymize the fossil genus Eccoptarthrus with this family—and consequently change the family name—has been rejected by most coleopterists.
