Distribution: Distributed through all the Holarctic region, with several species in Oceania and a few species in China and South America.

Statistics: 14 species in Palearctic, more than 40 species worldwide.

Host Plants: Populus, Salix (Medvedev & Roginskaya 1988).

Comments: As Hincks (1952) and later Gressitt & Kimoto (1963) mentioned, the generic name Chalcoides has been used for this genus, but the type species of Crepidodera is congeneric with the type of Chalcoides.

Diagnosis: Body small to medium sized. Color metallic blue, green or bronze, usually very shiny; sometimes pronotum and elytron differently colored.
Head pro-hypognathous, oval, more or less convex from lateral view. Frontal ridge long and narrow, forming T-shaped ridge with anterior margin of head capsule. Antennal calli raised, contiguous, well delineated from vertex and frontal ridge. Interantennal space not wider than diameter of antennal socket. Orbital line present. Eye sometimes small. Antenna 11-segmented, filiform.
Pronotum subquadrate, with transverse and longitudinal impressions basally. Procoxal cavity closed behind.
Elytra oval, more or less convex from lateral view. Humeral callus well developed. Elytral punctures arranged in striae; interspaces sometimes very narrow, flat. Epipleuron wide, subvertical.
Metatibia thin, cylindrical, slightly expanded and flattened apically. First metatarsal segment usually not longer than following two segments combined.
