Abstract

Otostigmus (Otostigmus) xizangensis n. sp., a new species of subgenus Otostigmus Porat, 1876 from Xizang, China, is described and illustrated. The new species is diagnosed as follows: antennae 17–19 articles (mainly 19), basal antennal articles cylindrical; forcipular tooth-plate with 4 teeth; tergites (5) 6–20 with complete paramedian sutures; well-developed lateral margination on tergites (6) 9–21; ultimate leg prefemora with four rows of spines, leg 20 with one tarsal spur. The coxopleural process of O. (O.) xizangensis n. sp. exhibits remarkable sexual dimorphism, being long and curved in females, short and straight in males.
