Description of two Stenohya species from China (Pseudoscorpiones, Neobisiidae), with comments on the exaggerated sexual dimorphic pedipalp in this genus.

Two Stenohya species belonging to the family Neobisiidae are diagnosed, described, and illustrated from China: Stenohyaspinatasp. nov. from Chongqing Municipality, and Stenohyahuangi Hu & Zhang, 2012 from Fujian Province. The male of S.huangi is reported for the first time. Diagnostic characters of this species are restricted based on the holotype and the new specimens.
