Chromatopelma (genus)

The Chromatopelma genus is a unique and distinctive group of tarantulas native to the Paraguaná Peninsula in South America. It is a monotypic genus, meaning it contains only one species, Chromatopelma cyaneopubescens, which is commonly known as the greenbottle blue tarantula. These tarantulas have garnered significant attention and popularity among hobbyists due to their attractive appearance and fascinating characteristics.

The greenbottle blue tarantulas are easily recognizable by their striking metallic blue legs and blue-green carapace, which earned them their common name. Their vibrant coloration, combined with their active nature and fast growth, makes them highly sought after by tarantula enthusiasts. These tarantulas are known for their agility and active behavior, adding to their allure and making them captivating to observe.

The taxonomic history of the Chromatopelma genus is interesting. Initially described by Embrik Strand in 1907 as Eurypelma cyaneopubescens, it was later moved to the genus Delopelma by Alexander Petrunkevitch in 1939. However, Delopelma and Eurypelma are now considered synonyms of the Aphonopelma and Avicularia genera, respectively.

In 1997, Gunter Schmidt recognized the distinct characteristics of Chromatopelma cyaneopubescens and created the genus Chromatopelma specifically for this species. The name “Chromatopelma” refers to the tarantula’s remarkable blue coloration. Schmidt differentiated Chromatopelma from Aphonopelma based on several features, including the scopulae (bristle-like structures) on the tarsus of the third leg, bristles that separate the metatarsus from the tarsus on the fourth leg, the presence of large posterior median eyes, and the presence of a single fused spermatheca in females.

The establishment of the Chromatopelma genus highlights the distinctiveness and unique characteristics of the greenbottle blue tarantula. Its vibrant coloration, active nature, and specific anatomical features set it apart from other related genera. As hobbyists and researchers continue to study and appreciate these remarkable creatures, the Chromatopelma genus remains a fascinating and significant part of the tarantula world.
