| - The genus Agra, whose range extends from southernmost Texas (USA) to northernmost Argentina, contains several hundred described and many more undescribed species. These beetles are rarely collected because they live in tropical forest canopies. Understanding of their phylogeny and distribution may provide data with which to test recently proposed hypotheses of tropical species richness and endemism, particularly the forest refugium/flood-zone hypothesis. A construction of the systematic framework from which such syntheses may be obtained is initiated herein. New methods of description are used to cover the several hundred species in less time and space, to provide a consistent numerical data base, and to use more efficiently and effectively the descriptive process. A key is given for the 5 groups of section Erythropus of Agra. A key, descriptions and type localities are given for 16 new species of Agra of the group A. erythropus: A. coleps (Cayenne, French Guiana), A. pseuderythropus (Cayenne, French Guiana) A. oiapoquensis (Oiapoque, Amapa, Brazil) A. falsisagax (Humaita, Amazonas, Brazil), A. dryas (Oiapoque, Amapa, Brazil), A. cobra (type area.sbd.French Guiana), A. perinvincta (Sao Paulo d'Olivenca, Amazonas, Brazil), A. invicta (type area.sbd.Amazonas, Brazil), A. ega (Ega [Tefe], Amazonas, Brazil), A. rhomboides (type area.sbd.French Guiana), A. yoda (Pariacabo, French Guiana), A. pennyi (Parque Nacional Amazonia, 63 km southwest of Itaituba, Para, Brazil), A. mniszechi (type area.sbd.French Guiana), A. sphenarion (Tarapoto, Peru), A. saltatrix (Taraooto, Peru) and A. maxli (Ega [Tefe], Amazonas, Brazil). Five natural subgroups containing 25 spp. are described. Their cumulative range extends from Peru east to the mouth of the Amazon River and north along the coast to Guyana. Most species are locally distributed. A dot map illustrates the range of each taxon.
