Abstract

Fauna of the genus Pandeleteius Schoenherr of Colombia, Venezuela, Trinidad, and the Lesser Antilles are revised in part. Six new species of Pandeleteius are described: P. trinidadensissp. nov. (P. angustirostris species group); P. sabanaensissp. nov. and P. bolivarisp. nov. (P. campestris species group, new concept); P. guriensissp. nov. and P. ductilissp. nov. (P. candidus species group, new concept); and P. clarkisp. nov. (P. modestus species group). The P. kirschi species group (new concept) is redefined based on male and female genitalia, and P. testaceipes Hustache is added to the species group. The other sex is described for three species formerly known from only one sex: the male of P. candidus Howden, male of P. arcanus Howden, and female of P. liberalis Howden. New findings on the post-pupal growth and morphology of the male and female genitalia are applied to the group- and species-level taxonomy. The key to the Pandeleteius species of Venezuela and Colombia is revised to include all the original species groups and subsequent changes, as well as all new taxa.

Résumé

On révise, en partie, les espèces appartenant au genre Pandeleteius Schoenherr habitant la Colombie, le Venezuela, Trinidad et les Petites Antilles. On décrit les six espèces suivantes: P. trinidadensissp. nov. (du groupe d'espèces P. angustirostris); P. sabanaensissp. nov. et P. bolivarisp. nov. (du groupe d'espèces P. campestris, nouveau concept); P. guriensissp. nov. et P. ductilissp. nov. (du groupe d'espèces P. candidus, nouveau concept); et P. clarkisp. nov. (du groupe d'espèces P. modestus). On redéfini le groupe d'espèces P. kirschi en s'appuyant sur des caractères génital mâles et femelles, ainsi P. testaceipes Hustache est ajouté au groupe. On décrit les individus du sexe opposés pour trois espèces connues que d'un des sexes, soit: le mâle de P. candidus Howden, le mâle de P. arcanus Howden et la femelle de P. liberalis Howden. On applique de nouvelles observations sur la croissance post-pupal et la morphologie des organes génitaux mâles et femelles à la systématique des niveaux groupes et espèces. On révise le tableau des espèces pour le Venezuela et la Colombie de façons a y inclure tout les groupes d'espèces et les changements subséquents, ainsi que toute les nouvelles espèces.
