Odontota can be distinguished by the following combination of characters:

• Body wedge-shaped or oblong
• the lateral margins of the pronotumpronotum:
  occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
  and the elytra without long, stiff spines
• the head without a frontal horn
• the pronotumpronotum:
  occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
  with a seta in each anterior angle, finely margined, without lateral teeth
• the apex of the elytra without a tooth-like projection
• the elytra with 10 rows of punctures for entire length plus short scutellar row, with 4 regular costae, costa 3 complete, humerus angulate without spine or tooth, apex regularly rounded
• the antennae thickened at apex, with 11-antennomeres
• leg with apical tarsomere bearing 2 claws
• abdominal sterna 1 and 3 without medial sulcus
• anterior margin of prosternumprosternum:
  contains two anterior coxal cavities
  not expanding toward mouth

strongly transverse, prominently raised, base subangulate.

Antenna: with 11-antennomeres; basal antennomere incrassate.

Pronotum: transverse, generally widest medially; lateral margin angulate in middle, bisinuate; dorsum transversely convex, basal depression present or absent.
