Euchromia irius (Boisduval, 1832)
[Glaucopis irius Boisduval, 1832] (type (TL: "Nouvelle Guinee") in BMNH)
iria sensu Rothschild, 1916
Glaucopis boisduvalii Montrouzier, 1856 [type (TL: Trobriand Island) not located]
Hira aruica Walker, 1864 [type (TL: Aru) not located]
aemulina Butler, 1877 [holotype (TL: "New Guinea" = PNG) in BMNH)
The colour bandation seems to vary in the broadness of the bands. However, more research is needed to prove if this indeed is just variation of one species or specific characters of different sibling species. Three examples of this "variation" are depicted below.
Euchromia irius is somewhat similar to E. creusa but irius has a maximum of four red bands (at least three bands) and creusa has five red bands. The white band in irius is broad and conspicuous while in creusa it is narrow and in many cases even lacking.
STATUS: Probably the most common Euchromia species from New Guinea. It is found from sea level up to high altitudes in all kinds of habitat.
