Abstract

Two new species are described in the Neotropical genus Agaporomorphus Guignot from Suriname: A. hamatocolessp. nov. and A. tortussp. nov. The species are included in a phylogenetic parsimony analysis of 13 morphological characters and all 12 known species. Two equally parsimonious arrangements are found with the only difference a rearrangement among the A. knischi clade. Agaporomorphus tortus belongs to the A. dolichodactylus group based on presence of an elongate, club-like lobe on the dorsal, basal surface of the male median lobe and long, subsinuate male mesotarsal claws and a small lobe at the apex of male mesotarsomere V. Agaporomorphus hamatocoles does not belong to a known species group and is phylogenetically isolated lacking synapomorphies characterizing the other groups, so the species is placed in its own species group. Male genitalia are illustrated for the new species and redrawn for all the species of the A. dolichodactylus group, and male mesotarsal claws are illustrated for A. tortus and redrawn for other members of the A. dolichodactylus group. New distribution records are reported for Suriname for the species A. colberti Miller and Wheeler and A. pereirai Guignot.
