Con gente del MACN, CEPAVE y Uruguay, recién describimos la araña Pikelinia schiapelliae (Filistatidae), hallada en arenales de Argentina y Uruguay. Muy simpática! (foto 1 por Damián Hagopián)

Happy to see this publication out! I am delighted to have collaborated with Vanesa Mamani and Daniel Proud on this article. This project features some of my earliest scientific drawings, created 30 years ago!

Sci-comm at its finest! Shahan Derkarabetian and I just published a systematic study of arachnids in the Magic: The Gathering card game (Magic: The Gathering). We discuss the evolution of spiders and other arachnids across the multiverse! Check it out: virginianaturalhistorysociety.com/wp-content/upl…

Very proud to see this study, led by our PhD student (at Aracnologia MACN) Vanesa Mamani, published. It addresses an intriguing taxonomic conundrum involving synonymy, a spurious locality, and intrasexual dimorphic males in Opiliones.

Sadness day to arachnology 😢

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.

La increíble textura de Sicarius sp. The incredible texture of Sicarius sp.

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.

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.

Uncovering the worldwide footprint of an ancient relictual lineage of harvestmen: new genus and species of Buemarinoidae from Australia (Opiliones: Laniatores: Triaenonychoidea) academic.oup.com/zoolinnean/art… Now fully citable, with a volume number.

Ready to see the love of my life in the dark! Deinopis sp., male, Argentina. 🫣😆

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.

🎉Excited to share our new paper in Zoosystema! Buemarinoidae, an enigmatic Opiliones family once known from six monotypic genera, is expanded with a redescription of Malagasy Flavonuncia pupilla + 4 new species. Read more: zoosystema.com/47/14 #Opiliones #Taxonomy #MACN

Arachnid of the week: Lola insularis Kratochvíl, 1937

Paper out🕷️📢! We explore the implications of different cheliceral morphotypes related to different trophic adaptations on the species' ability to undergo ecological release in the red devil spiders from the Canary Islands. Full text at Insect Conservation and Diversity: doi.org/10.1111/icad.1…

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. macnconicet.gob.ar/wp-content/upl…

Arachnid of the week is Troglochthonius doratodactylus Helversen, 1968
