Camelobaetidius Demoulin 1966

The genus Camelobaetidius, originally described by Demoulin in 1966, is one of the most species rich genera in Neotropics (Domínguez et al. 2006). In Venezuela, only Camelobaetidius alcyoneus (Traver) was described (Chacón et al. 2009). Here, four species are reported from Venezuela.
