Scientists say the rare Australian bee species is struggling to survive against habitat loss.
But scientists have warned the Pharohylaeus Lactiferus is facing increasing pressure to survive because of climate change, the loss of habitat, and the fragmentation of Australia's rainforest.
The last record of the endemic species was recorded in Queensland in 1923. At that time only six individual bees had ever been found.
But it was rediscovered following extensive sampling of almost 250 sites.
"Three populations were found by sampling bees visiting their favoured plant species along much of the Australian east coast, suggesting population isolation," Flinders University biological sciences Ph.D. candidate James Dorey said.
Mr. Dorey said a highly fragmented habitat and a susceptibility to bushfires might explain the rarity of Pharohylaeus Lactiferous.
His study also warned the species was even more vulnerable as they appeared to favour specific floral specimens and were only found near the tropical or sub-tropical rainforests.
He said future research should aim to increase the understanding of the bees' biology, ecology, and population genetics.
"If we are to understand and protect these wonderful Australian species, we really need to increase biomonitoring and conservation efforts, along with funding for the museum curation and digitisation of their collections and other initiatives," Mr. Dorey said.
His paper has been published in The Journal of Hymenoptera Research.
