Abstract

A sixth species of Macrosaccus (Gracillariidae), M. coursetiae sp. nov., is described. The larvae are leafminers of Coursetia glandulosa (Fabaceae). The parasitoid Chrysocharis walleyi (Eulophidae) has been reared from the leaf mines; a table summarizing the host records for this wasp is presented.

Etymology. The specific name is derived from the generic name of the host plant, Coursetia DC. The speciesgroup name of the moth is a latinized noun in genitive singular, gender feminine. It is combined with the generic name Macrosaccus of which the gender is masculine. Since the species-group name coursetiae is a noun in apposition its ending does not need to agree in gender with the generic name with which it is combined and must not be changed to agree in gender with the generic name (ICZN Art. 34.2.1).
