A new electric-blue tarantula species of the genus Karsh, 1892 from Thailand (Araneae, Mygalomorphae, Theraphosidae).

The enchanting phenomenon of blue coloration in animals arises from the fact that blue is one of the rarest colors found in nature, and it is a structural color that is produced by the arrangement of biological photonic nanostructures, rather than pigments. This unique coloration has evolved independently in many different species, adding to the fascination and diversity of coloration patterns in the animal kingdom. This study describes a new species of Karsch, 1892 from southern Thailand that exhibits a blue-violet hue resembling the color of electrical sparks.

A new genus of bamboo culm tarantula from Thailand (Araneae, Mygalomorphae, Theraphosidae).

Bamboo plays an important role in the animal world, including providing a nutritious food source, shelter, and habitat. Inside of bamboo culm, we discovered a new genus of tarantula, which we describe here as (♂♀). Specimens of this new tarantula were collected from Mae Tho, Mueang Tak district, Tak province, in Thailand, making it geographically distant from any other arboreal genera.
