Phasmomantella gen.?nov., a spectacular new genus of praying mantis from southern Central Vietnam (Mantodea, Mantidae, Deroplatyinae, Euchomenellini)

摘要

The new genus Phasmomantella gen.?nov. is created to accommodate the new species P.?nuichuana gen.?et sp.?nov. described from five adult females from Núi Chúa National Park in southern Central Vietnam. A second species, Phasmomantella pallida (Roy, 2001) gen.?et comb.?nov., is transferred from Euchomenella where it was originally described based on a single male specimen from the Nha Trang region in the Khánh Hòa Province. Phasmomantella gen.?nov. is placed in the tribe Euchomenellini of the subfamily Deroplatyinae. A comprehensive diagnosis and detailed descriptions are presented along with high-resolution photographs, measurements and a distribution map. The standardised measurements are illustrated and a new key is proposed for the tribe Euchomenellini. The unique biogeography and habitats of the collection site within Núi Chúa National Park are discussed in the light of possible endemism and importance for nature conservation.
