Los mordélidos son pequeños a moderados en tamaño, de 2 a 15 mm de longitud, con un cuerpo de forma peculiar que los distingue de prácticamente todos los otros coleópteros. En corte transversal el cuerpo es en forma de cuña. La cabeza y el protórax están encorvados hacia abajo y hacia atrás de forma tal que las mandíbulas apuntan hacia atrás. La parte trasera el cuerpo termina en punta, formada por el último segmento abdominal, el cual sobresale más que los élitros.
General appearance. 2–9 mm long. Body length/maximum body width 2.3–4.7. Elytral length/pronotal length 2.2–3.75. Base of prothorax not or scarcely narrower than the combined elytral bases. Greatest prothoracic width not narrower or only slightly narrower than the greatest elytral width. Beetles elongate; dorsally strongly convex (characteristically humped forward, and smoothly tapered to the uncovered tip of the abdomen); conspicuously necked; not waisted to somewhat waisted. Upper surfaces of body non-glabrous; not bristly; exhibiting scales or scale-like setae, or with neither scales nor scale-like setae.
Detailed morphology. Beetles not prognathous. Eyes not strongly protuberant; without bristles; finely facetted. Antennae short; 11 segmented. Antennal scape not swollen. Antennae filiform to gradually expanding acropetally, or clubbed. Antennal clubs 7 segmented (elongate, serrate). Antennal insertions hidden from above.
