Data from: A stable phylogenomic classification of Travunioidea (Arachnida, Opiliones, Laniatores) based on sequence capture of ultraconserved elements
Molecular phylogenetics has transitioned into the phylogenomic era, with data derived from next-generation sequencing technologies allowing unprecedented phylogenetic resolution in all animal groups, including understudied invertebrate taxa. Within the most diverse harvestmen suborder, Laniatores, most relationships at all taxonomic levels have yet to be explored from a phylogenomics perspective. Travunioidea is an early-diverging lineage of laniatorean harvestmen with a Laurasian distribution, with species distributed in eastern Asia, eastern and western North America, and south-central Europe. This clade has had a challenging taxonomic history, but the current classification consists of ~77 species in three families, the Travuniidae, Paranonychidae, and Nippononychidae. Travunioidea classification has traditionally been based on structure of the tarsal claws of the hind legs. However, it is now clear that tarsal claw structure is a poor taxonomic character due to homoplasy at all taxonomic levels. Here, we utilize DNA sequences derived from capture of ultraconserved elements (UCEs) to reconstruct travunioid relationships. Data matrices consisting of 317–677 loci were used in maximum likelihood, Bayesian, and species tree analyses. Resulting phylogenies recover four consistent and highly supported clades; the phylogenetic position and taxonomic status of the enigmatic genus Yuria is less certain. Based on the resulting phylogenies, a revision of Travunioidea is proposed, now consisting of the Travuniidae, Cladonychiidae, Paranonychidae (Nippononychidae is synonymized), and the new family Cryptomastridae Derkarabetian & Hedin, fam. n., diagnosed here. The phylogenetic utility and diagnostic features of the intestinal complex and male genitalia are discussed in light of phylogenomic results, and the inappropriateness of the tarsal claw in diagnosing higher-level taxa is further corroborated.

A checklist of the spiders (Arachnida, Araneae) of the Kirstenbosch National Botanical Garden, South Africa
<p>An annotated species list of spiders presently known from the Kirstenbosch National Botanical Garden is provided. The checklist was compiled from data collected from the South African National Survey of Arachnida (SANSA) database. A total of 170 spe-cies from 46 families and 128 genera are presently protected in the garden. The two most species-rich families are the Salticidae (20 spp.) and Thomisidae (20 spp.), followed by the Theridiidae (13 spp.) and Araneidae (12 spp.), while 18 families are represented by sin-gletons. The global distribution, endemicity, and conservation status for each species are provided and species of special concern are identified, as well as possible new species. Most of the species (82%) have a wide distribution range and are of Least Concern, 8.3% are Data Deficient and 17 species are of special concern. Only one species is endemic to Kirstenbosch, and 37 are Western Cape endemics.</p>

Final report on the diversity of the Mountain Zebra National Park, South Africa (Arachnida: Araneae)
<p>Two checklists have previously been published from the Mountain Zebra National Park. In 1988, only 32 species were recognised and in 2006, 43 species. In this final report, we list 150 species from 38 families, increasing the number of species recog-nised with 107 species. For the first time, we provide information on the endemicity and conservation status of the 150 species. The family Gnaphosidae was the most diverse with 17 species sampled, followed by the Salticidae with 15 species, and Thomisidae with 14. Ten of the families are known only from a single species. This is an inventory project of the South African National Survey of Arachnida (SANSA).</p>
qPCR results from design and partial validation of three novel eDNA qPCR assays for several common North American tick (Arachnida: Ixodida) species
<p>The range expansion of ticks to higher latitudes poses a severe threat to human health exposing human populations who had no prior contact with ticks to several harmful tick-borne diseases. Early detection of ticks in new areas is critical to help inform the public and medical professionals of the dangers associated with tick encounters. Environmental DNA represents a novel survey method that could provide reliable records of tick occurrences and timely warnings of their range expansions. In this study, we designed three novel eDNA qPCR assays for three common North American tick species (<em>Dermacentor variabilis</em>, <em>Amblyomma americanum</em>, and <em>Ixodes scapularis</em>) and tested them on samples of grasses collected from grasslands and forests in Illinois. We provide <em>in silico</em> and <em>in vitro </em>validation of all three assays, however we were unable to generate any positive detections from field samples. Our lack of eDNA detections likely stems from low eDNA deposition rates coupled with rapid degradation in grasslands and forests, a problem exacerbated by terrestrial eDNA sampling methods that are limited by volume of substrate. We provide recommendations for improving sample collection methods to increase detection probability in future efforts. Continued research should focus on the viability of eDNA to detect small terrestrial invertebrates, like ticks, and it potential as early warning indicator of the spread of vector-borne diseases.</p>
