Enischnispa Gressitt 1957b: 274





Type Species


Enischnispa calamivora Gressitt.



Enischnispa can be distinguished by the following combination of characters:

  • lateral margin of pronotum and elytra without long, stiff spines
  • head without frontal horn between antennae
  • pronotum with seta in each angle, flattened, slightly constricted basally and apically, lateral margin narrowly margined
  • anterior margin of prosternum not projecting forward, not partly covering mouth
  • less than 14 mm in length
  • elytra without transverse carinae forming an irregular net-like sculpture; interspaces 2, 4, and 8 costate, 6 prominent, concealing lateral margin in dorsal view, with 10 rows of punctures at base, 8 medially, 9 apically
  • antennae with 8-antennomeres



Narrow; subparallel; slightly convex; yellow with black markings or totally black; length 2.7 to 3.4 mm.

Head: large; vertex slightly depressed, medial carina present; with blunt projection between antennal bases; frons moderately developed; clypeus slightly emarginate; eye large, convex.

Antenna: ⅔ body length; with 8-antennomeres, slightly thickened apically; antennomeres 1 and 2 subequal in length; 1 subglobose; 2 slightly swollen apically; 3 longer than 2; 4 to 7 shorter; 8 as long as 4 to 7 combined, broadly rounded apically.

Pronotum: longer than wide; slightly constricted basally and apically; lateral margin curved, narrowly margined; anterior angle acute; anterior margin straight; posterior angle acute; posterior margin bisinuate; surface deeply punctate.

Scutellum: longer than wide; narrowed; subtruncate at apex.

Elytron: lateral margin straight, smooth; exterior apical angle rounded; apex rounded; sutural angle with small tooth; humerus rounded, not produced, slightly constricted behind humerus; with 10 rows of punctures at base, 8 rows medially, 9 apically, scutellar row absent; interspaces 2, 4, and 8 strongly costate, 6 prominent concealing lateral margin in dorsal view.

Venter: sparsely punctate.

Leg: short; robust; tibia truncate at apex.
