Twenty-nine specimens of Diplura collected from eight caves in China and Myanmar contain two new genera, Hubeicampa Sendra & Lips gen. nov. and Mueggejapyx Sendra & Komerički gen. nov., as well as four new species, Anisuracampa ywangana Sendra & Komerički sp. nov., Hubeicampa melissa Sendra & Lips gen. et sp. nov., Pacificampa wudonghuii Sendra sp. nov. and Mueggejapyx brehieri Sendra & Komerički gen. et sp. nov. These cave-adapted taxa showcase an impressive diversity in morphological adaptation (troglomorphy) to cave ecosystems. Their sensorial equipment, setae and receptors in the cupuliform organ have unique forms (H. melissa gen. et sp. nov.), as well as the pretarsus sticky surface (A. ywangana sp. nov. and H. melissa gen. et sp. nov.). Recent contributions on Asian diplurans, together with the taxonomic novelties shown in the present study, highlight the biogeographical importance of the Asian biodiversity. Asia is revealed as a continent with vast karst regions still waiting to be explored and new dipluran species waiting to be discovered.
Few species of Japygidae (Diplura) have been discovered in cave ecosystems despite their importance as large predators. A small collection of rare specimens of this hexapod group has allowed to explore the taxonomy of japygids from caves in New Zealand, Morocco and South Africa, and to describe one new genus: Imazighenjapyx Sendra & Sánchez-García gen. nov., as well as four new species: Austrjapyx wynbergensis Sendra & Sánchez-García sp. nov., Imazighenjapyx marocanus Sendra & Sánchez-García gen. et sp. nov., Opisthjapyx naledi Sendra & Sánchez-García sp. nov. and Teljapyx aotearoa Sendra & Sánchez-García sp. nov. For each of the new taxa we give a comprehensive description of their habitats. These new findings resulted in a revision of the distribution and allowed to re-evaluate the morphological traits of the fifteen cave-adapted japygids species already known worldwide. The functional morphology of the remarkable abdominal pincers of Japygidae and their adaptation to predation are discussed, as well as their potential role in mating behaviour.
