Diagnosis

Hybosispa can be distinguished by the following combination of characters:

• 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
  without a seta in any angle; quadrate
• femora not toothed
• elytra not costate, punctures in regular rows
• antennae with 11-antennomeres
• body subcylindrical

Head: moderately large; eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
large, wider above than below, finely faceted; fronsfrons:
upper anterior portion of head capsule above the clypeus
with triangular excavation divided by a longitudinal keel from antennal base to clypeal margin; clypeusclypeus:

triangular; maxillary palps with palpomeres 2 and 3 short, 4 oval, as long as 2 and 3 combined; antennaantenna:
3 to 11 segments, inserted in antennal pit in front of eyes
inserted into pit at side of eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped

Pronotum: transverse; parallel-sided; finely margined on anterior margin; depression present on either side of middle near side margin; seta absent in all angles.

Scutellum: as long as wide; pentagonal; cuspidate behind.

Elytron: wider than 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
at humeri, gradually narrowing apically, truncate posteriorly, part of pygidium exposed; with 10 rows of punctures plus scutellar row.

Venter: Mesosternummesosternum:
narrow between middle coxae, separated from metasternum by a transverse suture; forming the anterior part of the middle coxal cavities
more elevated than prosternumprosternum:
