Ictinus was an architect active in the mid 5th century BC. Ancient sources identify Ictinus and Callicrates as co-architects of the Parthenon. He co-wrote a book on the project – which is now lost – in collaboration with Carpion.
Iridomyrmex is a genus of ants called rainbow ants first described by Austrian entomologist Gustav Mayr in 1862. He placed the genus in the subfamily Dolichoderinae of the family Formicidae. It has 79 described species and five fossil species. Most of these ants are native to Australia; others are found in Asia and Oceania, and they have been introduced to Brazil, New Zealand, and the United Arab Emirates. Fossil species are known from China, France, and the United States.
The meat ant, also known as the gravel ant or southern meat ant, is a species of ant endemic to Australia. A member of the genus Iridomyrmex in the subfamily Dolichoderinae, it was described by British entomologist Frederick Smith in 1858. The meat ant is associated with many common names due to its appearance, nest-building behaviour and abundance, of which its specific name, purpureus, refers to its coloured appearance. It is among the best-known species of ant found throughout Australia; it occurs in almost all states and territories except for Tasmania. Its enormous distribution, aggression and ecological importance have made this ant a dominant species.
Jalmenus eichhorni, the northern hairstreak or northern imperial blue, is a butterfly of the family Lycaenidae. It is endemic to Queensland, Australia, including Cape York.
Jalmenus inous, the Inous blue or varied hairstreak, is a butterfly of the family Lycaenidae. It is endemic to coastal Western Australia.

Iridomyrmex anceps is an ant species of the genus Iridomyrmex. It has a very large distribution in multiple continents, but it is mainly distributed in northern Australia. Some specimens were found in multiple islands, and some were even found and collected in the United Arab Emirates.
Iridomyrmex anteroinclinus is a species of ant belonging to the genus Iridomyrmex. Described in 1993 by Shattuck, the Iridomyrmex anteroinclinus is native to Australia and has only been observed in Western Australia.
Iridomyrmex bicknelli is a species of ant belonging to the genus Iridomyrmex. The species is distributed in every single state and territory in Australia. Iridomyrmex bicknelli was described by Emery in 1898.
Iridomyrmex cephaloinclinus is a species of ant belonging to the genus Iridomyrmex. It was described by Shattuck in 1993, the species is abundant to several states in Australia.
Iridomyrmex alpinus is a species of ant of the genus Iridomyrmex. It was described by Heterick and Shattuck in 2011.
Yantaromyrmex is an extinct genus of ants first described in 2013. Members of this genus are in the subfamily Dolichoderinae of the family Formicidae, known from Middle Eocene to Early Oligocene fossils found in Europe. The genus currently contains five described species, Y. constrictus, Y. geinitzi, Y. intermedius, Y. mayrianum and Y. samlandicus. The first specimens were collected in 1868 and studied by Austrian entomologist Gustav Mayr, who originally placed the fossils in other ant genera until the fossils were reviewed and subsequently placed into their own genus. These ants are small, measuring from 4 to 6 mm in length and can be characterized by their trapezoidal shaped head-capsules and oval compound eyes that are located slightly to the rear of the capsules midpoint, with no known ocelli present.
Iridomyrmex conifer is a species of ant in the genus Iridomyrmex. Endemic to Australia, it was described by Forel in 1902.
Iridomyrmex galbanus is a species of ant in the genus Iridomyrmex. Described by Shattuck in 1993, the ant is mainly confined to the Eyre peninsula in South Australia, but other populations of the species have been identified in several other states in Australia.
Iridomyrmex innocens is a species of ant in the genus Iridomyrmex. Described by Forel in 1907, the species is endemic to Australia, mainly confined in Western Australia, but the species is more common in areas with higher rainfalls within the Darling Ranges.
Iridomyrmex rufoniger is a species of ant in the genus Iridomyrmex. It was described by Lowne in 1865. The species is endemic to Australia and introduced to several other countries.
