Stegomerus Wood, 1967: 129

(Fig. 35)

Type of genus

Stegomerus vulgaris Wood, 1967 .

Diagnosis

Stegomerus can be diagnosed by the short, almost spherical antennal scape, the antennal club, which is mostly symmetrical and with one or two visible procurved sutures, by the rounded lateral margin of the pronotum with bifurcating setae on the hypomeron, and the broadly divided apical plate of the proventriculus.

Female

Eye long and broadly emarginated. Frons simple and convex. Antennal scape short, almost spherical. Antennae with five funicle segments. Antennal club with procurved sutures. Lateral margins of pronotum rounded. Hypomeron with bifurcating setae. Proventriculus with open median suture in the apical plate. Crop spines stout. A cluster of spines is present on the posterior side of the proventriculus.

Male

No obvious external differences from the female. Aedeagus not examined.

Distribution

Central America, South America.

Remarks

Nine species known. We transfer Cryphalomorphus parvatis Wood, 1974 from Eidophelus based on the diagnostic characters above. The species may be conspecific with Stegomerus pygmaeus Wood, 1967 .
