Olethrius cariosicollis ( Fairmaire, 1877)

( Fig. 15 )

Opheltes cariosicolli s Fairmaire, 1877: 167; 1879: 111; 1881: 470; Lameere, 1883: 6. Stenodontes (Nothopleurus) cariosicollis ; Lameere, 1902: 96; 1903 a: 130; 1913: 13 (cat.); 1919: 33. Olethrius cariosicollis ; Lameere, 1920: 137 (comb. nov.).

Nothopleurus cariosicollis ; Dillon & Dillon, 1952: 4; Fragoso & Monné, 1995: 219.

Along with Olethrius macrothorax , O. cariosicollis ( Fairmaire, 1877) appears incorrectly assigned to Nothopleurus ( e.g. Dillon & Dillon 1952; Fragoso & Monné 1995). Likewise, this species does not belong to Olethrius or Opheltes

The main characters that prevent the assignment of O. cariosicollis ( Fig. 15 ) to Olethrius are: scape short, reaching at most the posterior edge of eyes; length of antennomere III subequal to IV; prothorax strongly retracted laterally between the posterior and lateral angles, mainly in females; pronotum strongly punctate throughout in both sexes, without impunctate facets. In Olethrius the scape is long, distinctly surpassing the posterior edge of eyes in both sexes, antennomere III is longer than IV (clearer in males), the prothorax is not retracted laterally between the posterior and lateral angles (mainly in males), and the pronotum has impunctate facets in both sexes.

The inclusion in Opheltes as established in the original description, or in Nothopleurus or Hovorodon gen. nov. is also precluded, primarily by the shape of the prothorax, the sculpture of the pronotum, and by the presence of short setae on the pronotum and scutellum. In Opheltes , the form and sculpture of the prothorax is very similar to that of Olethrius in both sexes, and of the species assigned to Hovorodon gen. nov. In Nothopleurus the pronotum has a large, smooth, shining area on the disc. In addition, Opheltes and Nothopleurus have the pronotum and scutellum glabrous.

As an additional note, the page citation for this species has been cited incorrectly by almost all authors that referenced this species (including Fairmaire, 1879, 1881): instead of page 180, the correct page is 167.
