Total: 86 species

Legend:

A: Australia, B: Borneo, C: Celebes, Ce: Ceylon, I: Indo - China, In: India, J: Java, M: Malaya, Ma: Madagascar, Mo: Moluccas, N: New Guinea, NC: New Caledonia, P: Philippines, S: Sumatra, SC: Southern China, Se: Seychelles

Notes:

- There is extreme variation within some species e. g. grouping within the maxima-complex (Borneo? - Celebes `N. eymaeę - New Guinea) is still unresolved. Another difficult species is N. singalana from Sumatra. Jebb and Cheek have created a new name for the G. Bandahara form (`N. diatasę) but didnęt consider other variants such as the very small form from G. Tudjuh etc..

- N. philippinensis is still in the list though Jebb and Cheek mention it under N. alata without having seen the type. For clarification observations in the field are necessary as well as collecting new specimen from the locus classicus.
