A comparison of series of specimens of the filaria and malaria transmitting forms of Anopheles (Ano.) barbirostris Van der Wulp, form Sulawesi and Flores, with specimens of the non-vector forms from Java, peninsular Malaysia and Thailand, shows that the 2 forms are conspecific and supports the synonymy of the subspecific name innominata Stoker and Koesoemawinangoen, 1949 (Knight and Stone 1977). This conclusion agrees with that of Lien et al. (1977).
