Australian Stick Insect Revision Reveals Five Species, Not Two

A University of Sydney team reclassified Australian stick insects in the genus Anchiale, identifying five distinct species where only two were previously recognized. The study describes two new species, including one with unique 'lidded' eggs, and corrects a decades-long misidentification. These findings highlight hidden biodiversity in well-studied regions and offer practical benefits for managing insect outbreaks in forestry and agriculture.

Genetic analysis confirms Leopardus tilcayo as first new wild cat species in over a century

Scientists have officially described Leopardus tilcayo, a small wild cat from Bolivia’s Yungas cloud forests, as a distinct species. This marks the first new living cat species identified in over 100 years. Genetic analysis reveals the species diverged from other tiger cats approximately 1.4 million years ago. While locals had long known the animal, its distinct genetic lineage was only confirmed recently. The discovery highlights urgent conservation needs, as the species’ habitat faces threats from logging and agriculture, and its population size remains unknown.

Australian researchers reveal five distinct stick insect species hidden within two known names

A University of Sydney team has identified two new stick insect species and restored a third to full status in Queensland, revealing that what were thought to be two species are actually five distinct lineages. The discovery, published in Austral Entomology, highlights significant gaps in insect diversity knowledge despite extensive citizen science data.

Leopardus tilcayo: Bolivia's cloud forest yields first new wild cat species in a century

Scientists have identified Leopardus tilcayo, a small spotted wild cat from Bolivia's Yungas region, as a distinct species. This marks the first new cat species described in over 100 years. The discovery, based on genetic analysis of two individuals, highlights significant gaps in global biodiversity knowledge and raises urgent conservation concerns for this vulnerable animal.

Leopardus tilcayo: The first new wild cat species in a century

Scientists have officially described a new wild cat species, Leopardus tilcayo, found in Bolivia’s cloud forests. This marks the first new feline species identified in over 100 years. The animal, smaller than a house cat, was confirmed through genetic testing after being mistaken for a domestic kitten. Its discovery highlights the urgent need for conservation in the region’s rapidly disappearing habitats.

Bolivian Cloud Forest Yields First New Wild Cat Species in a Century

Researchers have identified a new wild cat species, the tilcayo (Leopardus tilcayo), in Bolivia’s Yungas cloud forest, marking the first new large mammal cat discovery in 100 years. The species, smaller than a house cat, was confirmed through genomic analysis of 38 samples, revealing it diverged from other lineages 1.4 million years ago. While local communities knew of the animal, its scientific description is novel, prompting urgent conservation efforts as its habitat faces agricultural expansion.

Taylor Swift Becomes Namesake for 12 Newly Discovered Plant-Feeding Insects

UC Riverside researchers describe 12 new Australian plant-feeding true bugs and name the genus Swiftiephylus in honor of Taylor Swift, including species Swiftiephylus taylorae, amator, intrepidus and poetorum; the naming aims to raise awareness of insect biodiversity and conservation, and the insects live on she-oaks and are not pests.

Milpe Rain Frog Emerges as a Truly New Species After Taxonomic Mix-Ups

A team re-examined 1902 frog specimens from Ecuador and found that what was long labeled Pristimantis subsigillatus actually encompassed a distinct, living population now named Pristimantis milpe (Milpe Rain Frog). Through holotype re-evaluation and DNA testing, researchers showed the subsigillatus holotype is conspecific with a different species (P. latidiscus), while P. milpe is widespread in the Pacific basin and easily identifiable by its call and female color pattern. The finding highlights how common species can be misclassified for decades and suggests auditing other Pristimantis classifications.

Milpe Rain Frog Emerges as Its Own Species After Decades Of Taxonomic Mix-Ups

A re-examination of a 1902 frog holotype revealed that populations once labeled Pristimantis subsigillatus are actually a distinct species, Pristimantis milpe (Milpe Rain Frog), widely distributed in Ecuador and southern Colombia, highlighting a decades-long taxonomic mix-up and prompting calls to audit similar classifications.

Time to Redraw the Human Family Tree

New fossil data and genetic analysis cast doubt on the traditional three-genus view of human relatives (Homo, Australopithecus, Paranthropus), showing these groups often aren’t true clades and traits evolve in mosaic ways. Some researchers suggest folding Australopithecus and Paranthropus into a broader Homo genus to reflect actual relationships and to accommodate interbreeding over millions of years. The proposed reclassification would improve alignment with evolutionary history but would blur familiar distinctions and change everyday language about humans’ place on the primate family tree. We’re in a transition toward taxonomy that mirrors real relationships.

Taxonomy rethink: expand Homo to include early cousins in human evolution

Monash University researchers argue that recent fossil discoveries blur boundaries between Homo, Australopithecus, and Paranthropus, proposing to expand the genus Homo to better reflect complex, non-linear human evolution and reduce future reclassifications as new fossils emerge.

Hominin Taxonomy Reimagined: Australopithecus and Paranthropus Could Join Homo

Dr. Ian Towle proposes folding Australopithecus and Paranthropus into Homo to better reflect shared ancestry and gene flow, arguing that brain size, tool use, and other traits no longer reliably separate genera; citing non-monophyly in Australopithecus and interbreeding among close relatives, he suggests expanding Homo back to about 4–5 million years ago (anchored at A. anamensis) and redefining Hominini and Hominina; the paper is published in the American Journal of Biological Anthropology.

Should Homo expand to include Australopithecus and Paranthropus?

New fossil data and genetic analyses suggest the traditional three-genus classification of human relatives (Homo, Australopithecus, Paranthropus) doesn’t reflect true evolutionary branches, with evidence that Australopithecus and Paranthropus may not form real clades; some researchers propose folding them into an expanded Homo genus to better map our family tree, though this would erase familiar distinctions and require changes in language and interpretation of human evolution.

Antarctic Whaling Find Unmasks a New Oceanic Squid Family: Mobydickia poseidonii

A squid recovered from a sperm whale’s stomach during the 1955–56 Antarctic whaling season was long misidentified as Ancistrocheirus lesueurii but has been reclassified as the sole representative of a new oceanic-squid family, Mobydickidae, with the new genus Mobydickia and species poseidonii. Described in 2025, the finding rests on distinctive anatomy (including unique hooks and absence of photophores) and, lacking DNA data, uses morphology from the holotype—the specimen traveled from a private collection to the Natural History Museum in London and then to the ICM-CSIC in Barcelona for study. This marks the first new oceanic-squid family since 1998 and highlights how old collections can reveal hidden biodiversity, though it does not imply a living population or ecological significance beyond taxonomic refinement.

A tiny Amazon patch could house 40,000 insect species, many undiscovered

A Brazilian megaproject is surveying insects across a 10,000‑hectare central Amazon site from ground to canopy, deploying multi‑level traps and a blitz of methods. After 14 months they’ve collected about 5.5 million specimens, with around 600,000 slated for DNA sequencing, and preliminary data suggest as many as 40,000 species may inhabit this patch—roughly 0.7% of the world’s estimated six million insect species—work being carried out by ~400 taxonomists who will describe and name new species, often drawing on Indigenous languages, rivers and regional history.
