#Pseudoscorpions are #interesting and #biologically diverse #arachnids that are often overlooked due to their #smallsize. Many species are #grounddwellers or live in deadwood. The largest #taxon is the #Chernetidae, with approximately 726 extant #species. L. Laibe et al. (2025) described a new species of its genus #Attaleachernes from the eastern #Amazon region and also characterized the #habitat.

How many spiders and pseudoscorpions does it take to make one of the world’s greatest taxonomists?

Former Perth curator Mark Harvey is one of the few people on Earth to have described 1,000 new species, many of them arachnids. Colleagues say his legacy is ‘unquantifiable’

#Arachtober 5: the last order of arachnids I have found, pseudoscorpions! They look kind of like scorpions without tails; they are found basically everywhere on earth but Antarctica, but they are absolutely tiny and live in places like under tree bark, under rocks and logs, in leaf litter, etc., so you will rarely see them unless you're looking for them. Sometimes they can be found clinging to the legs of larger flying insects with their little claws, or indoors eating booklice and other tiny household insects.

The ones in my garden are so small you might take them for mesostigmatid mites at first glance. This one has captured a soil-dwelling mite of some kind.

The rain this morning brought out plenty of arthropods in the garden, including these two arachnids. A podocinid mite (https://bugguide.net/node/view/247922), a tiny mesostig with extremely long, thin front legs terminating in forked hairs; and a chthoniid pseudoscorpion, with its clawed pedipalps. Strangely akin.

Four newly-discovered species of #cave-dwelling #pseudoscorpions have jaws like dragons and are completely blind

not sure if it's a great idea to use imaginary animals as reference point to describe a new species?

I was just poking around the garden today in a spare moment and had two unexpected arachnid discoveries!!

1. A hackled orbweaver (_Uloborus glomosus_), one of the very few venomless spiders, that also makes orb webs with a fuzzy, glueless silk not often used for aerial webs—I rarely come across them and never, I think, in my own garden.

2. A new kind of pseudoscorpion—not the tiny yellowish cthoniids I'm used to, but a HUGE beast with sturdy claws, like 3mm long! I think it's family Chernetidae.
