Hispines of the World


Stenopodius Horn 1883: 301





Type Species


Stenopodius flavidus Horn.



Stenopodius can be distinguished by the following combination of characters:

  • the lateral margins of the pronotum and the elytra without long, stiff spines
  • the head without a frontal horn
  • the pronotum with a seta in each anterior angle
  • the apex of the elytra without a tooth-like projection
  • the elytra with 8 or 10 rows of punctures, some species with 3 regular costae,
  • the antennae short, clavate, with 8-antennomeres, antennomere 7 narrower than 8
  • the prosternum does not expand anteriorly to partly cover the mouth
  • tarsomere 3 not bilobed



Head: small; vertex not prominent; frons vertical; eye large, oval, facets numerous.

Antenna: clavate, short, extends a short way beyond apical margin of pronotum, 8-antennomeres; antennomere 8 oval, pointed at apex.

Pronotum: wider than long; in most species apex more or less prolonged (lobed) at middle and sinuate at each side; base wider than apex, broadly lobed, sinuate laterally, overlapping base of elytron, except in middle.

Scutellum: subquadrate; apex truncate, feebly arcuate or slightly emarginate.

Elytron: oblong‑oval; about ½ longer than wide; parallel-sided and broadly rounded in apical ¼; lateral and apical margins more or less serrulate; 8 or 10 rows of large, circular punctures.

Leg: glabrous; metafemur slightly longer than tibia; tarsomeres not dilated, with pale setae beneath, first 3 tarsomeres subequal, 3 emarginate above, 4 as long as 1 to 3 combined; claws feebly arcuate.
