Goyachalepus can be distinguished by the following combination of characters:

• Body elongate
• the lateral margins of the pronotumpronotum:

  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 8 rows of punctures for entire length and 3 regular costae, humerus angulate without spine or tooth
• the antennae thickened at apex, with 11-antennomeres, antennomere 3 2.5x length of 2 or 4
• leg with apical tarsomere bearing 2 claws
• anterior margin of prosternumprosternum:
  contains two anterior coxal cavities
  not expanding toward mouth
