A New Species of Carpotroche (Achariaceae) from Honduras and Nicaragua

Abstract. Carpotroche caceresiae, a newly delimited species from the Caribbean drainage of Honduras and Nicaragua, is described and illustrated and its extinction threat assessed as Near Threatened (NT) according to IUCN criteria. Carpotroche caceresiae has previously been confused with C. platyptera, a species characterized by a densely pubescent lower leaf surface and red fruits lacking crests between the wings; in contrast, C. caceresiae has sparsely pubescent lower leaf surface and green fruits with crests between the wings. Carpotroche crassiramea and C. glaucescens, typified with Costa Rican material, and hitherto included in the synonymy of C. platyptera, are treated here as distinct morphological identities; a list of the specimens examined and referred to these names are provided.
