          Abstract

          Two new species are described in the Desmopachria convexa species group in the Neotropical genus Desmopachria Babington: D. manco sp. nov. (Guyana), and D. mortimer sp. nov. (Costa Rica). Two subgroups, the D. convexa-convexa and the D. convexa-signata groups are defined. Desmopachria convexa-convexa species are from North and Central America and have a subapical articulable lobe on the male lateral lobe that is large and elongate and extends well beyond the slender, oblique apex of the lateral lobe. Desmopachria convexa-signata species are from South America and have a subapical articulable lobe on the male lateral lobe that is small and discrete and does not extend beyond the truncate apex of the lateral lobe. The male genitalia of all recognized species in the D. convexa group are redrawn from the literature. New species are illustrated from specimens and described species have morphological features redrawn from published illustrations.

          Resumen

          Se describen dos especies nuevas en el grupo de especies Desmopachria convexa del género neoprópical Desmopachria Babington: D. manco sp. nov. (Guyana) y D. mortimer sp. nov. (Costa Rica). Se definen dos subgrupos, el D. convexa-convexa y D. convexa-signata . Las especies de D. conveza-convexa son de Centro y Norte América, y tienen un lóbulo subapical articulado en el lóbulo lateral del macho que es grande y alargado y se extiende mucho más allá del ápice delgado y oblicuo del lóbulo lateral. Las especies de D. convexa-signata son de América del Sur y tienen un lóbulo subapical articulado en el lóbulo lateral del macho que es pequeño y discreto y no se extiende más allá del ápice del lóbulo lateral. Los genitales masculinos de todas las especies reconocidas en el grupo D. convexa se vuelven a dibujar a partir de la literatura. Las especies nuevas se ilustran a partir de los ejemplares examinados y las especies descritas tienen características morfológicas redibujadas a partir de ilustraciones publicadas.
