In a win for biodiversity, CSIRO, Australia’s national science agency, has revealed 139 new species were named and described by its researchers and partners in the past year.
With only about 25 percent of Australia’s species known to science, scientific names are vital for researchers, governments and the community to better understand the nation’s vast ecosystems.
CSIRO scientist John Pogonoski, who helped name four new species of marine fish, said the work highlighted the importance of scientific collections including CSIRO’s ³Ô¹ÏÍøÕ¾ Research Collections Australia.
“We named three new species of small, brightly-coloured anthias by comparing specimens of related species held in fish collections,” Mr Pogonoski said.
“New species of anthias are still being recognised because they are rarely encountered due to being outside of normal diving depths, small in size, or living in habitats difficult to sample,” he said.
Mr Pogonoski said the new Silverspot Weedfish, Heteroclinus argyrospilos, was described from only two known specimens collected from south-western Australia by researchers on the former CSIRO Research Vessel Southern Surveyor in 2000 and 2005.
“The Weedfish were found 55 to 100 metres below sea level, which is interesting because they live deeper than other known members of the genus,” he said.
In addition to 117 insects named during the past year, scientists named 14 other invertebrates including 11 jumping spiders, one millipede, one earthworm and one marine trematode which was discovered inside a fish.
CSIRO Entomologist Dr David Yeates said the known but newly named ant Anonychomyrma inclinata was particularly special, with its support of the endangered Bulloak Jewel Butterfly, Hypochrysops piceatus.
“The ecological requirements for this beautiful butterfly are very narrow, which is probably why it is so rare,” Dr Yeates said.
“The ant species we’ve now named needs to be nesting in a mature bulloak, Allocasuarina luehmannii. The butterfly caterpillars live under bark and are carried to soft bulloak leaves to feed at night by ‘babysitter’ ants. The ants protect the caterpillars from predators and receive a sugary gift from the caterpillars, a win-win for both species,” he said.
The newly-named species also highlight the importance of collaboration, with most scientific papers involving authors from multiple scientific collections and universities across Australia and overseas.
“Working together with our research community to name species is incredibly important – it is the first step in Australia understanding and managing its biodiversity,” Dr Yeates said.
“As a country, we are still in the very exciting phase of species discovery,” he said.

CSIRO acknowledges the many research partners involved in collaborative projects to describe and name the new species featured here and the Traditional Owners of all lands on which they occur.
