Type Species

Cyperispa hypolytri Gressitt.

Diagnosis

Cyperispa 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, not projecting over head, with 2 deep pits near posterior margin and pit in each posterior angle
  • 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 1½x length of 1 and 2 combined
  • elytra with strong costa between each row of punctures
