Donghui Wu, Wenying Yin


Two new species of Xenylla from Jilin Province, Northeast China are described and illustrated. Xenylla changlingensis, new species clearly differs from the closely related species X. piceeta Stebaeva & Potapov, 1994 in the presence of dorsal la2 of thoracic segments II and III, the absence of ventral seta p2 on abdominal segment II, 1 median ventral seta above the retinaculum on abdominal segment III, and lack of teeth on the mucro. Xenylla changchunensis, new species is similar to the species X. osetica Stebaeva & Potapov, 1994. However, it is separable from the latter by the presence of a furca, a tenaculum, and the ventral chaetotaxy on abdominal segment III.
