Two species in Central America are known by the name Centrosema pubescens Benth. Description and differentiation of the two taxa are presented, along with a record of the nomenclatural history of confusion with other species [C. galeottii Fantz, C. macrocarpum Benth., C. molle Mart, ex Benth., C. schiedeanum (Schlecht.) Williams & Clements, and C. virginianum (L.) Benth.], and commentary on the type specimen of C. pubescens. Evidence from the type indicates the name C. pubescens should be applied to an upland Central American species currently known as C. galeottii or C. scbiedeanum. The widespread, lowland tropical species bearing the name C. pubescens must be renamed, with C. molle having priority. En Centroamérica son conocidas dos especies con el nombre de Centrosema pubescens Benth. Se presenta la descripción de los dos taxa, junto con la historia nomenclatural de confusión con otras especies [C. galeottii Fantz, C. macrocarpum Benth., C. molle Mart, ex Benth., C. schiedeanum (Schlecht.) Williams & Clements, y C. virginianum (L.) Benth.], y un comentario sobre el tipo de C. pubescens. Una vez examinado el tipo aparecen evidencias que indican que el nombre de C. pubescens debe ser aplicado a una especie de las tierras altas de Centroamérica conocida normalmente como C. galeottii o C. schiedeanum. La especie tropical de las tierras bajas conocida como C. pubescens debe ser renombrada, teniendo prioridad C. molle.
