Comparing ethanol rehydration techniques: effects on spider morphology and DNA integrity Open
Ethanol curation plays a crucial role in preserving museum specimens, especially soft-bodied arthropods. Dehydration happens as a result of less than ideal storage and preservation conditions. If rehydration is desired for a specimen, then…

High and hardy: Cold‐tolerant generalists inhabit extreme elevations in Rocky Mountain <i>Pardosa</i> spiders Open
Evaluating the characteristics that allow species to inhabit high‐elevation environments is central to understanding the historical drivers of montane biogeography and forecasting where species will live as our planet gets warmer. Over the…

Advances in Understanding the Karyotype Evolution of Tetrapulmonata and Two Other Arachnid Taxa, Ricinulei and Solifugae Open
Background/Objectives: Arachnids are a megadiverse arthropod group. The present study investigated the chromosomes of pedipalpid tetrapulmonates (orders Amblypygi, Thelyphonida, Schizomida) and two arachnid orders of uncertain phylogenetic…

Living with the enemy: behavioral study of Myrmecicultor chihuahuensis Ramírez, Grismado & Ubick (Araneae: Myrmecicultoridae) Open
The spider, Myrmecicultor chihuahuensis Ramírez, Grismado & Ubick 2019 is a myrmecophage. In an earlier study, we found that the spider's cuticular hydrocarbon (CHC) profile overlapped with that of its prey. In the present study, we photog…

Camel spider trait evolution demonstrates repeated patterns of convergence (Arachnida: Solifugae: Eremobatidae) Open
Morphology has long been used to classify and identify living organisms. However, taxonomic descriptions are often limited to qualitative descriptions of size and shape, making identification difficult due to the subjective language used t…

Neglected no longer: Phylogenomic resolution of higher-level relationships in Solifugae Open
Considerable progress has been achieved in resolving higher-level relationships of Arthropoda in the past two decades, largely precipitated by advances in sequencing technology. Yet, dark branches persist in the arthropod tree of life, pri…

Trophic specialization of a newly described spider ant symbiont, Myrmecicultor chihuahuensis (Araneae: Myrmecicultoridae) Open
The spider Myrmecicultor chihuahuensis Ramírez, Grismado & Ubick (Myrmecicultoridae) was described in 2019 and hypothesized to be a myrmecophile, living inside the nests of Novomessor (Myrmicinae) and perhaps also Pogonomyrmex (Myrmicinae)…

An assessment of function, intraspecific variation, and taxonomic reliability of eremobatid ctenidia (Arachnida: Solifugae) Open
Camel spiders, members of the order Solifugae, are a diverse but poorly understood order of arachnids. The conserved morphology within many groups in the order makes species delimitation and identification challenging. In the North America…

An Updated Checklist of the Spiders (Arachnida: Araneae) of Arkansas Open
A total of 510 species of spiders representing 43 families and 215 genera are herein reported from Arkansas. The most diverse families of state spiders were Salticidae (64 species), Lycosidae (59 species), Araneidae (55 species), and Gnaph…

Solifugae of Canada Open
The Solfugae fauna of Canada includes three known species: Eremobatesdocolora Brookhart and Muma, E.scaber (Kraepelin), and Hemerotrechadenticulata Muma. It is expected that as many as four additional species may be found in Canada. Only o…

Revision of the camel spider genus Eremocosta Roewer and a description of the female Eremocosta gigas Roewer (Arachnida, Solifugae) Open
A recent phylogenetic analysis demonstrated that the solifuge genus Eremocosta (Eremobatidae), although not monophyletic, formed a strongly supported group, rendered paraphyletic by the exclusion of E. acuitlapanensis, which we herein dete…
