Hispines of the World


Pseudocalaspidea Jacobson 1899: 245





Type Species


Alurnus cassidea Westwood.



Pseudocalaspidea can be distinguished by following combination of characters:

  • the lateral margin of the pronotum and the elytra lacking long, stiff spines
  • the head lacking a frontal horn
  • the pronotum having a tuft of setae in each angle and much narrower than the base of the elytra
  • the filiform antennae having 11-antennomeres, with antennomere 3 as long as 4 to 6 combined
  • the elytral punctures not being in regular rows
  • the subcordiform (nearly heart-shaped) elytra lacking costae



Body large (20-25 mm).

Head: pubescent; medial sulcus present; frons punctate.

Antenna: with 11-antennomeres; 3 as long as 4 to 6 combined.

Pronotum: much narrower than elytra, convex; widest at base, narrowing anteriorly; pubescent, more dense on anterior and lateral margins; finely punctate; anterior angle rounded; with tuft of setae in each angle; basal margin bisinuate.

Scutellum: elongate, triangular.

Elytron: subcordiform (nearly heart-shaped), highly convex; with irregular punctures; no costae; humeral angle produced; laminate laterally.
