2 to 5 mm long
Elongate, more or less cylindrical.
Head and base of antennae entirely covered by the pronotum (prothorax) and therefore not visible from above.
The pronotum has a fine grain-like aspect, it is not quite as wide as the elytra at their base (identification criterion), it has a sharp triangular median protuberance on top.
The slightly grainy elytra are striated and punctuated by big, deep dots in regular lines. They are covered by a fine yellowish pubescence that is curved backward.
Clubbed antennae, clubs formed of three rather elongate articles.
Reddish brown to chocolate brown
