Two new blind species of Sinella are described from Nanjing, China. Sinella quinseta sp. n. from Purple Mountain possesses unique 5+5 central macrochaetae on Abd. II, and can be distinguished from other species of the genus by the postlabial chaetae and the dorsal chaetotaxy. Sinella qixiaensis sp. n. from Qixia Mountain is characterized by the paddle-like S-chaetae of Ant. III organ and the sm...

Genetic variation for thermal plasticity plays an important role in the success or failure of a species with respect to the colonization of different thermal habitats and the ability to deal with climatic change. The aim of this paper is to study the relative contribution of the additive and non-additive components of genetic variation for the slope of the temperature reaction norm for juvenile...

A study of all available specimens of E. quinquelineata Börner, 1901 from different museums and private collections, revealed that more than one species was involved. We reached this conclusion by using conventional taxonomical characters and patterns of macrochaetotaxy. We redescribe here the specimens most probably identical to Börner's original material, and describe three new species, one f...
