Prophalangopsis obscura Gorochov, 1986. Trudy Zool. Inst. Akad. Nauk SSSR, 143: 96. Prophalangopsis obscura Otte, 1997. Orth. Spec. File., 7: 315. Prophalangopsis obscura Gorochov, 2001. Journ. Orth. Rese., 10 (2): 364. Prophalangopsis obscura Desutter-Grandcolas, 2003. Zool. Scripta, 32 (6): 538. Walker (1869) described P. obscura based on a single male specimen collected from northeastern India. Since then, no additional material has been discovered. In this study, we report two female specimens collected from Motuo, Tibet. In general appearance, they resemble the male of P. obscura. We believe they are females of the elusive of P. o b s c u r a. They are described below.
