%X Se presenta una revisi¨®n de la morfolog¨ªa de la c¨¢psula genital del macho de las 15 especies de Eulaema y una caracterizaci¨®n del aparato copulador de cada una de ellas. Usando 11 caracteres genitales y corporales se presenta un an¨¢lisis preliminar de las especies que confirma la divisi¨®n subgen¨¦rica actual y plantea la existencia de tres grupos de especies en el subg¨¦nero Eulaema s.str. Se presenta tambi¨¦n una clave actualizada para los machos de Eulaema. Although the morphological characters of the male genital capsule and the associated sternites of the five genera of euglossine bees is generally well known, the male genital morphology of many species of the genus Euglossa and Eulaema has not been described before. The genital characters can be useful for the determination of species and for the examination of phylogenetic relationships. The morphology of male genital capsules of all 15 Eulaema species is presented. 30 dry conserved and needled specimens were observed. Eleven genital and non-genital chracteres are proposed to explore the relationships between the species of Eulaema, including the subgeneric status. The results confirm the present division of the genus into two subgerera (Eulaema s.str. and Apeulaema) and three groups are proposed in Eulaema s.str. An updated key for the males of Eulaema is presented.
