The taxonomic revision of the tarantula genus Aphonopelma in 2016 marked a significant milestone in understanding this group of spiders. This comprehensive study, led by Hamilton, employed an integrative approach combining phylogenomic, morphological, ecological, and geospatial data to redefine the taxonomy and evolutionary relationships of Aphonopelma species in the United States.
Reduction in Recognized Species:
The revision reduced the number of recognized Aphonopelma species in the U.S. from 55 nominal species to 29 valid species. This was achieved through the synonymization of 33 previously described species and the description of 14 new ones.
Improved Species Delimitation:
By integrating genomic data and advanced morphological analyses, the study resolved long-standing issues in species identification. It addressed challenges such as sexual dimorphism and overlapping morphological traits, which had previously complicated species delimitation.
Phylogenetic Insights:
The revision proposed a new species tree based on Anchored Enrichment data, identifying five major lineages within Aphonopelma. These lineages were linked to specific geographic regions and ecological niches, including biodiversity hotspots like the California Floristic Province and Madrean Pine-Oak Woodlands.
Conservation Implications:
The refined taxonomy has important implications for conservation efforts by providing a clearer understanding of species distributions and their ecological requirements.
The 2016 revision of the Aphonopelma genus had a notable impact on the tarantula hobby, influencing how enthusiasts approach species identification, conservation, and breeding.
Improved Species Identification:
The revision clarified the taxonomy of Aphonopelma, reducing confusion caused by misidentifications and synonymized species. This helps hobbyists ensure they are acquiring accurately labeled specimens, which is crucial for ethical breeding and maintaining genetic purity.
Challenges in Breeding:
The reduced number of recognized species means hobbyists must be cautious to avoid accidental hybridization. This is particularly important as hybrids can dilute genetic lines and complicate taxonomy further.
Enhanced Interest in Native Species:
The revision brought attention to lesser-known Aphonopelma species within the U.S., increasing their popularity in the hobby. Enthusiasts now have access to better tools for identifying and appreciating these tarantulas.
Overall, this taxonomic update not only improved scientific understanding but also fostered a more informed and conservation-focused tarantula-keeping community.
This revision brought modern scientific rigor to Aphonopelma taxonomy, which had suffered from inconsistent historical classifications. It set a new standard for mygalomorph spider research by demonstrating the value of integrative taxonomic approaches. The study not only clarified the evolutionary history of Aphonopelma but also provided tools such as identification keys for both sexes, aiding future research and conservation efforts.

Taxonomic revision of the tarantula genus Aphonopelma Pocock, 1901 (Araneae, Mygalomorphae, Theraphosidae) within the United States
This systematic study documents the taxonomy, diversity, and distribution of the tarantula spider genus Aphonopelma Pocock, 1901 within the United States. By employing phylogenomic, morphological, and geospatial data, we evaluated all 55 nominal species in the United States to examine the...
