Plusieurs specimens de Camptocercus du Rio Uracoa (nord-est du Vénézuéla) ont été identifiés à Camptocercus australis var. dadayi décrit de Colombie par Stingelin (1913). Sur la base de l'étude morphologique des individus vénézuéliens et des données de la littérature, le statut de ce taxon, d'abord rattaché à la forme australienne (australis), puis à la forme paléarctique (lilljeborgi) de Camptocercus, est discuté. L'ensemble des caractères propres aux populations sud-américaines permet de les séparer des formes australienne et paléarctique, et de leur attribuer un rang spécifique.
Abstract
Several specimens of Camptocercus from the Rio Uracoa (north-east Vénézuéla) have been identified as Camptocercus australis var. dadayi, previously described from Colombia by Stingelin (1913). On the basis of a morphological study of the Venezuelan specimens and data from the literature, the status of this taxon is discussed, especially its relationship to the Australian form (australis) and to the palaearctic form (lilljeborgi) of Camptocercus. The group of characters appropriate to the south american populations facilitates their separation from the australian and palaearctic forms and their assignment to a specific rank.
