Australian stick-insect count rises from two Anchiale species to five

A published reassessment now separates five Anchiale stick-insect species where two had been recognized, including two newly distinguished in far north Queensland. The University of Sydney and The Guardian both tie the result to a paper in Austral Entomology. The change is a taxonomic revision, not a measured effect on farms or conservation status.

The new count

A reassessment separates five Anchiale stick-insect species where two had been recognized. The University of Sydney said the group previously treated as two species contains five. That is a change in how specimens are named, not a claim that three species appeared this year. The count itself is the published result. Naming changed; the insects did not suddenly appear this season.[1]

Queensland

The Guardian reported two stick-insect species, newly distinguished in far north Queensland, in a paper in Austral Entomology that corrects a mistaken identification. Those two sit inside the university's five-species count. The newspaper and the university are describing the same revision, not two competing discoveries.[2], [1]

What the revision does not measure

The University of Sydney described the result as a taxonomic revision and said agricultural harm and conservation effect were not measured. Readers can take the species count as the finding. A change in names leaves crop damage, a new pest, and any protection listing unmeasured.[1]
