A Reconsideration of the Classification of the Spider Infraorder Mygalomorphae (Arachnida: Araneae) Based on Three Nuclear Genes and Morphology
TLDR
A reevaluation of mygalomorph phylogeny using the rRNA genes 18S and 28S, the nuclear protein-coding gene EF-1γ, and a morphological character matrix proposes a “road map” for future sampling across the infraorder with the aim of solving many remaining questions that hinder mygalomorphic systematics.
An evaluation of sampling effects on multiple DNA barcoding methods leads to an integrative approach for delimiting species: a case study of the North American tarantula genus Aphonopelma (Araneae,
TLDR
This investigation allowed us to integrate methodologies into an efficient, consistent, and more effective general methodological workflow for estimating species boundaries within the mygalomorph spider genus Aphonopelma.
A NEW SPECIES OF VAEJOVIS (SCORPIONES, VAEJOVIDAE) FROM SONORA, MEXICO
TLDR
Vaejovis pequeno, a new species of scorpion previously confused with V. waueri, is described and illustrated from Sonora, Mexico and is compared to that species.
Testing species boundaries in the Antrodiaetus unicolor complex (Araneae: Mygalomorphae: Antrodiaetidae): "paraphyly" and cryptic diversity.
TLDR
A molecular phylogenetic approach using nuclear 28S rRNA and mitochondrial cytochrome c oxidase subunit I genes to test the general efficacy of species boundaries in the Antrodiaetus unicolor spider species complex provides evidence that An.
Taxonomic revision of the tarantula genus Aphonopelma Pocock, 1901 (Araneae, Mygalomorphae, Theraphosidae) within the United States
TLDR
This systematic study documents the taxonomy, diversity, and distribution of the tarantula spider genus Aphonopelma Pocock, 1901 within the United States and proposes 33 new synonymies and a proposed species tree based on Anchored Enrichment data.
An exploration of species boundaries in turret-building tarantulas of the Mojave Desert (Araneae, Mygalomorphae, Theraphosidae, Aphonopelma).
TLDR
This work employed five different approaches for delimiting species in a group of closely related tarantulas from the Mojave Desert in the southwestern United States, demonstrating that the taxonomy of these spiders as presently defined underestimates actual species-level diversity and the group is in need of revision.
Molecular phylogeny and biogeography of an ancient Holarctic lineage of mygalomorph spiders (Araneae: Antrodiaetidae: Antrodiaetus).
TLDR
The first phylogenetic analysis of species-level relationships based on molecular data obtained from the mitochondrial (cytochrome c oxidase subunit I) and nuclear (18S and 28S rRNA) genomes is presented and supports the relatively early divergence of Antrodiaetus roretzi.
Evaluating the efficacy of continuous quantitative characters for reconstructing the phylogeny of a morphologically homogeneous spider taxon (Araneae, Mygalomorphae, Antrodiaetidae, Antrodiaetus).
TLDR
The results show that the use of continuous quantitative characters for phylogenetic reconstruction may be inappropriate for reconstructing Antrodiaetus phylogeny and indicate that due caution should be exercised before employing this character type in the absence of other independently derived sources of characters.
Integrative species delimitation and conservation of tarantulas (Araneae, Mygalomorphae, Theraphosidae) from a North American biodiversity hotspot
The Madrean Sky Islands of northern Mexico and the south‐western United States are located in the Madrean pine–oak woodlands ‘biodiversity hotspot’. This area is renowned for its exceptional flora
Integrative species delimitation reveals cryptic diversity in the southern Appalachian Antrodiaetus unicolor (Araneae: Antrodiaetidae) species complex
TLDR
This study demonstrates the efficacy of genomic‐scale data for recognizing cryptic species, suggesting that species delimitation with one data type, whether one mitochondrial gene or morphology, may underestimate true species diversity in morphologically homogenous taxa with low vagility.
