Lithobius ( Ezembius ) polyommatus sp. n. and Lithobius ( Ezembius ) dulanensis sp. n. (Lithobiomorpha: Lithobiidae), two new species from Qinghai-Tibet Plateau, China

Lithobius ( Ezembius ) polyommatus sp. n. and Lithobius ( Ezembius ) dulanensis sp. n. discovered from Qinghai-Tibet Plateau, China, are described. The two new species are morphologically similar, but could be distinguished by having mostly 12 ocelli other than 14 ocelli, anterior accessory spur absent versus present on legs 14, dorsal sulci on male 14th legs absent versus present and dorsal lateral setae short, only the largest as stout as the general setae instead of only long setae on the second article of the female gonopod. A key to the Chinese species of Ezembius is presented.
