2.5−2.8 mm long (mean = 2.64 mm; n = 5); 2.4−2.8 times as long as wide. This species can be distinguished by declivital interstriae 2 bearing a row of 3−5 denticles that are larger than those on other interstriae; and declivital interstriae 1 distinctly impressed.
This species has a very similar appearance and size to several Ambrosiophilus species which also have 3−4 denticles on declivital interstriae 2. The two genera are easily separated by the pronotal sculpturing: disc punctate in Ambrosiophilus and asperate in Ambrosiodmus.
