NOTE: A. brevicorne was listed by Macfarlaneet al. (2010: 427) without any indication of doubt regarding its establishment in New Zealand. The genus Adelium was indicated as 'D = doubtfully established in New Zealand' by Leschenet al. (2003: 23), so in the absence of any evidence to indicate that this doubt can now be safely removed, I maintain the question mark for both genus and species
