This ogre-faced spider (Deinopis seriata) was collected over 120 years ago and is the type specimen described by Eugène Simon in 1906.

Exciting news! Yesterday, we published the starting point of our revision of the harvestmen family Kimulidae. The paper provides a redescription of the type species of Kimula, the family type genus, and also describes a new species from Puerto Rico! doi.org/10.11646/zootaxa.586… – at Ciudad Autónoma de Buenos Aires, Argentina
Yesterday, Vanesa successfully defended her PhD thesis. It has been a privilege to mentor her over the past 10 years, from undergraduate student to PhD graduate. Today, she embarks on her career as an independent scientist. I couldn't be prouder. Congratulations, Dra. Mamani! 🎉 – at Ciudad Autónoma de Buenos Aires, Argentina

New paper out! mapress.com/zt/article/view/…
We revise South American triaenonychids formerly placed in Ceratomontia and propose the new genus Maurymontia, honoring Emilio Maury.
Three new species described, incl. M. grismadoi.
Happy New Year! 🎉

The holotype of Maurymontia mborore, a new genus and species of Triaenonychidae recently described by my friends and colleagues Williams Porto and @abelaracno. From Misiones, Argentina. We found a single male in a rocky area within the subtropical woodlands by sifting litter.
We are pleased to share our traditional report on the new genera and species described by the staff of MACN during 2024 (more precisely, between December 2023 and November 2024). You can download it from the link at the bottom of this post.

Loxosceles galianoa, una nueva especie de araña del noroeste árido argentino. Bautizada en honor a María Elena Galiano, es pariente cercana de L. laeta, pero vive en ambientes naturales. En el artículo, también discutimos la evolución de la genitalia femenina en Loxosceles.

Now fully citable, with a volume number.
Deinopis spiders are incredibly photogenic, perhaps due to their two enormous eyes that provide them with exceptional night vision. This is a male (notice its boxing glove-shaped pedipalps, which are used during mating), photographed in Buenos Aires.
Male and female of the opilionid Sadocus polyacanthus photographed near Lake Moquehue, Neuquén, Argentine Patagonia. Species Sadocus are among the largest and most colorful opilionids. Lake Moquehue marks the northernmost limit of this species' distribution in Argentina.

New to the the UK: the harvestman Siro rubens.
I have now found an additional location in Bristol close to my previous ones. Publication to follow.
