Necydalinae is a small of longhorn beetles (Cerambycidae) historically classified as a tribe within Lepturinae but now recognized as a distinct subfamily. The group is characterized by unusually short for cerambycids, giving them a superficial resemblance to rove beetles (Staphylinidae). Most are or mimics. The subfamily contains only two : Necydalis (Europe, Asia, North America) and Ulochaetes (western North America).

Identification
Distinguished from other Cerambycidae by short exposing abdominal segments.

Within Cerambycidae, separated from Lepturinae by morphological characters supporting status.

Appearance
Beetles with markedly abbreviated that leave most of the exposed, unlike typical longhorn beetles where elytra cover the entire abdomen. Body form slender and elongated. Most exhibit coloration and patterning that mimics bees or .
Distribution
Holarctic distribution. Necydalis occurs in Europe, Asia, and North America. Genus Ulochaetes is restricted to western North America.
