Abstract
Two species of Eurycnema occurring in Australia are
described and figured. Previously, various species were linked
together in the literature and Australian specimens invariably
listed as Eurycnema goliath (Gray 1834).
Brief notes on distribution, biology, and habitat are presented,
in addition to keys to adults and eggs and the first descriptions
of the males of Eurycnema osiris (Gray, 1834) (Australia)
and Eurycnema nigrospinosa Redtenbacher 1908 (Papua New
Guinea). Eggs of all four Eurycnema species are figured for
comparison and published synonyms are corrected. Lectotypes have been
designated for E. goliath, E. viridissima Kirby 1904 (a
synonym of E. goliath) and E. cercata Redtenbacher 1902.
E. stenocerca Redtenbacher 1908 and E. cercata are listed
as new synonyms of E. osiris, and E. magnifica Kirby 1904 is
a new synonym of E. goliath. [KEY WORDS: Eurycnema,
