Sometimes, a collection of new species turns out to be… no new species!

Takahiro Sugiyama, Ryutaro Goto, and Chloé Fourreau began studying the unique ectoparasitic scale worm Gastrolepidia clavigera in part because of its fascinating diversity of color, likely contributing to its ability to camouflage on sea cucumbers. After some genetic work, they found that this entire rainbow of scale worms all actually seem to belong to the same species!

Takahiro Sugiyama, Ryutaro Goto, and Chloé Fourreau’s paper “Host specific camouflage in a holothurian-ectoparasitic scale worm: testing the host-race hypothesis using COI and genome-wide SNP data” is in volume 173 of Marine Biology

Donard Geci fell into studying spiders by accident, but now he can’t imagine his life without them. He’s one of the only entomologists in the Balkans, a hotspot for spiders as well as plenty of other flora and fauna. It’s difficult, he says, “but you have many things to do here because many groups are unexplored.”

Trapdoor spiders are masterful architects, and there is so much work to do in order to better understand their relationships to one another. Fortunately, Donard isn’t deterred at all and wants to encourage even more scientists to study the amazing quantity of life found in the Balkans.

Donard Geci’s paper “Trapdoor spiders of the family Nemesiidae Simon, 1889 (Araneae: Mygalomorphae) from Kosovo” is in volume 20, issue 2 of Arachnology.

There are plenty of taxonomists who use museum collections as a resource, but not everyone makes collections the basis of their work. Rodrigo Dios studies Tachinid flies, a group that displays some of the most diverse parasitism behavior of all animals. By reorganizing and rediscribing museum specimens, he finds that we have a lot to learn from both flies and museum collections. “It's crazy,” says Rodrigo, about working in collections. “You can actually assess all this knowledge, all this variation between time and between space as well. It's like infinite knowledge.”

Rodrigo Dios’ paper “Taxonomic update on Cordyligasterini, new generic synonyms and new species of Neosophia Guimarães” is in volume 29 of Entomological Science.

“The queen especially was not like, like totally not like mad mad, but like mad at him…”

That analysis is from Charleigh (age 8), who I talked to along with her dad Jesse (older than 8) about the 1998 classic A Bug’s Life! We discussed serious matters such as the number of legs ants have, if insects have blood, and if the movie missed an opportunity by not including a dung beetle (I think they did).

Charleigh and Jesse co-host the amazing podcast arthropod adventures, which teaches listeners about arthropods they might see in their backyard. Stay inquisitive and never stop learning with me as I talk to them in this very silly bonus episode!

Hi everyone, incredibly it's time for the third biennial New Species Census! Every two years I ask listeners to answer a few questions about who they are, how they listen, and what they would like from the podcast in the future.

Take the survey: https://forms.gle/V8G9VSKxfvaxhxdx5

The survey will be open until February 13th 2026, after which time I'll post a summary of the feedback on instagram.* Please take a few minutes to share your thoughts! I'm so grateful to everyone who listens to this little hobby podcast, and your feedback really helps it to grow.

If you have general feedback or have missed the window, you can always email me at newspeciespodcast@gmail.com. Thank you as always for listening!

*Please note there are a few people confused - the New Species Podcast instagram is @newspeciespodcast! There is another account called New Species which is not me.

Do you ever wonder if your pet could be a new species? Paleontologist Benedikt Kästle took a closer look at his, and it led to a brand new genus and species! Also known as woodlice, these popular pets are easy to keep and easier to enjoy for the way they skitter and roll up. Benedikt explains that his scientific background can help members of the isopod community connect the valuable experience they have from rearing isopods to the broader research community, where much about isopods is still unknown.

Benedikt does this both through his instagram account and in his conversations with hobbyists from around the world, and it makes an impact. This new species is one of many that went undescribed for many years. Now its name is known from Martinique to Germany and beyond. Listen to this episode for a story that celebrates the humble roly poly in all its diversity and mystery.

Benedikt Kästle’s paper “Description of a new genus and species of terrestrial isopod (Oniscidea, Armadillidae) endemic to Martinique” is in volume 47 issue 29 of Zoosystema.

Stoneflies, or Plecoptera, are an order of insects with around 4,000 species. But that’s about to change. In her paper “Stonefly systematics: past, present, and future,” Anna Eichert and her colleagues from around the world map out the way stoneflies have changed as a group over time, some of the factors that shape our current understanding of the stoneflies, and what can change in the future to make sure our knowledge of stonefly diversity continues to grow. Learn from Anna’s account of her experiences and her passion for stoneflies in this episode, and next time you encounter a stream, flip over a rock or two.

Anna Eichert’s paper “Stonefly systematics: past, present, and future” is in volume 9, issue 4 of Insect Systematics and Diversity.

The genus Adelopsis is one of the many groups of LBB’s, ‘little brown beetles’ that often get left behind or unidentified by researchers. Eduardo Gomyde is a scientist giving them a closer look. “We're not just identifying species,” he explains, “but we are also analyzing and understanding the finer scale of the [features] that help us to differentiate them.”

Using Scanning Electron Microscopy, Eduardo and his coauthor carefully examined the tiniest of details. To find these specimens they had to sort through countless vials of “bycatch”, material leftover from other research that gets deposited in museum collections. Listen in as Eduardo describes his work, and learn about the great joy he takes in giving the LBB’s the attention and care they deserve.

Eduardo Gomyde’s paper “Revisiting the concept of ‘ultra evolved’ aedeagi of Adelopsis Portevin, 1907 (Coleoptera: Leiodidae: Cholevinae: Ptomaphagini) using scanning electron

microscopy, with description and redescription of species” is in volume 17 issue 1 of Megataxa.
