  Yinanyphaena gen. nov., a new ghost spider genus with descriptions of five new species and seven new combinations from China (Araneae, Anyphaenidae) Abstract A new genus, Yinanyphaena Wang & Mi, gen. nov ., of the family Anyphaenidae Bertkau, 1878, is proposed based on molecular phylogenetic results and morphological evidence. Five new species collected from the Qomolangma National Nature Reserve, Xizang, China are described: Y. haochuni Wang & Mi, sp. nov . (♂♀), Y. jinhuai Wang & Mi, sp. nov . (♂♀), Y. qomolangma Wang & Mi, sp. nov . (♂♀), Y. shikaii Wang & Mi, sp. nov . (♀), and Y. xufeii Wang & Mi, sp. nov . (♀). In addition, seven new combinations transferred from Anyphaena Sundevall, 1833 are also proposed: Y. cibagou (Wang & Mi, 2024), comb. nov ., Y. linzhi (Wang & Mi, 2024), comb. nov ., Y. rhynchophysa (Feng, Ma & Yang, 2012), comb. nov ., Y. shufui (Wang & Mi, 2024), comb. nov ., Y. tibet (Lin & Li, 202...

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

Abstract

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 Chilobrachys Karsch, 1892 from southern Thailand that exhibits a blue-violet hue resembling the color of electrical sparks. Photographic illustrations, a morphological description, and the natural habitat of the new species are given. The diagnosis, palpal-bulb structures, spermathecae, and stridulatory organ morphology of related species are discussed.
