Seven new species of Lonchocarpus (Millettieae, Papilionoideae) are described and illustrated: L. bracteolatus, endemic to Honduras; L hydrophilus, endemic to Guatemala, L. nebularis, endemic to Panama, and L. sericocarpus, endemic to Nicaragua. Two are found in the Gulf of Mexico's basin: L. barbatus and L. multifoliolatus, and L. congestiflorus is found in the mountains from Chiapas to Honduras. These species belong to sect. Densiflori Benth., sect. Obtusifolii (Benth.) M. Sousa and sect. Standleyi M. Sousa. A lectotype is designated for L. wendtii M. Sousa, since 2 collections were cited as the type.
