| Abstract | |
A recent study of specimens in the Museum National d'Histoire Naturelle, Paris, allowed for the recognition of two new species of Hypselotropis: H. jekeli sp. nov. from Colombia and H. jordani sp. nov. from Brazil. Hypselotropis jekeli sp. nov. is characterized by: longitudinal carina of rostrum entirely raised from apex; sides of rostrum tricarinate; antennae short, reaching only antebasal carina of prothorax; segments II-VIII narrowed and feebly impressed; lacking longitudinal carina on pronotum; lacking lateral carina on prothorax; prosternum without either furrow or ante-coxal depression; elytra strongly impressed along interstriae 1 and 2; ante-apical tubercles on interstria 4; pygidium impressed only on each side of longitudinal furrow, subtruncate at apex; and ventrite V strongly impressed, slightly projected at apical angles. Hypselotropis jordani sp. nov. is distinguished by the lack of a pronotal impression; short male antennae, reaching only middle of prothorax; and meso-and metafemora lacking dark vitta. A key to species and illustrations are provided. A cladistic reanalysis of the genus included 41 characters and 19 ingroup and 5 outgroup taxa. The resulting two most-parsimonious cladograms corroborated previous hypotheses of the relationships among Ptychoderini genera and the monophyly of Hypselotropis, with a new topology for the species relationships.
