Synonomys

Ekagonia Maulik 1916: 571.

Type Species

Javeta pallida Baly.

Diagnosis

Javeta can be distinguished by the following combination of characters:

• lateral margin of 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 elytra without long, stiff spines
• head without frontal horn between antennae
• pronotum pronotum:
  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 seta in each angle, flattened, never constricted basally, lateral margin narrowly margined
• anterior margin of prosternumprosternum:
  contains two anterior coxal cavities
  not projecting forward, not partly covering mouth
• less than 14 mm in length
• antennae with 11-antennomeres, antennomere 3 shorter than 1 and 2 combined
• pronotum pronotum:
  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
  slightly prolonged over head, with 10 deep pits, pubescent on anterior ½
• elytra with interspace 4 costate
