Synonomys

 

None.

Type Species

 

Hispa metallica Fabricius.

Diagnosis

 

Stenispa can be distinguished by the following combination of characters:

  • the lateral margins of the pronotum and the elytra without long, stiff spines
  • body elongate, parallel-sided
  • the head without a frontal horn; mouthparts not projecting forward
  • the pronotum with a seta in each anterior angle, wider than long
  • the apex of the elytra without a tooth-like projection
  • the elytra without costae, parallel-sided, posterior margin smooth, slightly wider than base of pronotum
  • the antennae with 11-antennomeres, filiform

Description

 

Body cylindrical or flattened; parallel‑sided or narrowing posteriorly.

Head: small, rounded; frons concave; maxillary palp with palpomere 1 small, 2 and 3 obconical, subequal in length and width, 4 oval, acuminate; antenna inserted close to eye in shallow pits, divided by longitudinal keel; eye oval, finely faceted, slightly prominent.

Antenna: with 11‑antennomeres; antennomeres 1 to 2 subglobose; 3 to 10 cylindrical, 3 longer than 4; 11 subacute, slightly dilated toward apex.

Pronotum: quadrate; slightly narrower than elytra; anterior margin rounded; lateral margin straight.

Scutellum: pentagonal or subcylindrical.

Elytron: elongate; slightly convex; narrowing apically; lateral and apical margins finely dentate; with 10 rows of punctures plus scutellar row.

Venter: metepisternum very narrow at middle; prosternum narrow, longitudinally furrowed; abdominal sternites 1 and 2 with suture obsolete in middle.

Leg: short; robust; femur stout; tibia not arcuate, slightly flattened; tarsomeres dilated, densely pubescent beneath, tarsomere 4 with nearly half its length projecting beyond 3; claws stout, moderately arcuate, divaricate.
