Abstract: Necterosoma timorense sp. nov. is described from a forest reserve at Mt. Mutis,
West Timor. It is the third species of Necterosoma W. J. Macleay, 1871 found
outside of Australia. Necterosoma timorense sp. nov. can be distinguished from
all hitherto known species by the more robust and broader body, the distinct
subhumeral expansion of female elytra, and the form of male genitalia. The new
species is lotic, being collected from small pools of an intermittent stream,
partly shaded by eucalypt forest. Altogether 12 species of Necterosoma are now
described.
