Synonomys

Euryspa Gemminger & Harold 1876: 3598 (misspelling).

Type Species

Eurispa vittata Baly.

Diagnosis

Eurispa 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, without tubercles at antennal bases
  • 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 and posterior angle
  • the apex of the elytra without a tooth-like projection, scutellar row present
  • the prosternumprosternum:
    contains two anterior coxal cavities
    does not expand anteriorly to partly cover the mouth
  • tarsal claws present, not equal in length

Description

Body narrowly elongate, cylindrical.

Head: short, not elongate before eyes, without tubercles at antennal bases; vertexvertex:
occupies the area behind and between the eyes
convex, rugose-punctate; labrumlabrum:
triangular, joined to the clypeus and the oral orifice
very short; maxillary palps long, palpomeres 2 to 3 obconic, 4 oval, thicker than 3; mentum small, subcordiform; labial palps short, palpomere 3 oval; eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
small, rounded.

Antenna: 1/3 body length; slightly thickening apically; with 11-antennomeres, antennomere 1 subglobose; 2 to 3 subcylindrical, longer than 1; 4 to 6 shorter, subequal in length; 7 to 10 obconic, slightly longer than 6; 11 slightly pointed at apex.

Pronotum: longer than wide; lateral margin straight, narrowly margined; anterior angle with seta; surface densely punctate, each puncture with pale seta.

Scutellum: small, rounded at apex.

Elytron: apex with elongate projection; surface punctate-striate, each puncture with pale seta, scutellar row present; finely costate.

Venter: prosternumprosternum:
contains two anterior coxal cavities
narrow between coxae, triangularly expanded behind; mesosternummesosternum:
narrow between middle coxae, separated from metasternum by a transverse suture; forming the anterior part of the middle coxal cavities
trapezoidal.

Leg: short, robust; femurfemur:
largest part of the leg; more or less cylindrical, attached at base to trochanter and at apex to tibia
without tooth; tarsal claws not equal in length.
