Abstract
The Tullbergiidae of Tibet is studied for the first time and the genus Metaphorura Bagnall, 1936 is firstly recorded in China. Metaphorura motuoensis sp. n. from southeastern Tibet is described and illustrated. It is characterized by the presence of 1+1 pseudocelli on thoracic segment I, few vesicles (14 -16) on PAO, pseudocellar formula as 11/111/11111, all pseudocelli of type II, setae p4 on abdominal segment V as microsetae, weakly differentiated sensory seta p3 on abdominal segment V, absence of median process on Abd VI. In addition, Mesaphorura yosii (Rusek, 1967), Mesaphorura hylophila Rusek, 1982, and Prabhergia imadatei Tamura & Zhao, 1996 are recorded in Tibet for the first time. The type specimens of P. imadatei are re-examined and errors in the original description of chaetotaxy are corrected.
Highlights
The knowledge of the taxonomy of Tullbergiidae from China is quite insufficient and only five species have been recorded to date (Rusek 1967; Tamura and Zhao 1996; Gao 2007; Bu et al 2013; Bu and Gao 2015).There are no records of Tullbergiidae from Tibet
Nearly 200 specimens belonging to the family Tullbergiidae were obtained. They were identified as four species including one new species of the genus Metaphorura Bagnall, 1936
The type specimens are deposited in Shanghai Natural History Museum (SNHM), Shanghai, China

N. is characterized by the presence of pseudocelli on thoracic segment I, few simple vesicles (14–16) on PAO, pseudocellar formula as 11/111/11111, all pseudocelli of type II, p4 on abdominal segment V as microsetae, less differentiated sensory setae p3 on abdominal segment V, absence of median process on Abd VI.
