Differs from Neocuris cf. viridimicans by its almost granular colouration underlain by darker tones, more pronounced puncturation, less rounded shape, and distinctive broader aedeagus.

While it is possible that this species may prove to be Neocuris viridimicans Fairmaire, 1877, another species, treated here as Neocuris cf. viridimicans, has generally been regarded as the more likely contender. Examination of the type specimens housed in Paris is needed for confirmation.
In SA Museum collections, N. sp. Dark green has sometimes been confused and included amongst N. cf. viridimicans but can be readily distinguished by its aedeagus, general morphology, sculpturing and colouration. Its emergence and active period appears to be a little earlier than in that species and it has been collected from a more diverse range of hosts. Its distribution in SA is largely associated with the Mt Lofty-Flinders Ranges block, while N. cf. viridimicans occurs in mallee districts.
