Abstract: In 1996, H C Zhang′s an article "Mesozoic insects of Orthophlebiidae (Insecta, Mecoptera) from Junggar basin, Xinjiang, China" was published in Act. Palaeont. Sin., 35(4): 442-445. This article included 5 old species and 5 new species. Among them an old species—Mesopanorpa obscura (Martynov, 1927) includes 3 specimens: ① NIGP126376 (92-T-22/K3), ② NIGP126377 (58SK15/K3), ③NIGP126378 (92-T-22/K1), and ④ another specimen: NIGP126379 (91-T-30/K). Through study on the taxonomy, three specimens are homonym, and are revised respectively for two new named species and one affinis species as NIGP126378 (92-T-22/K1) for Protorthophlebia (Protorthophebia) aff. obscura (Martynov, 1925) Martynov, 1927; NIGP126377 (58SK15/K3) for Protorthophlebia (Protorthophlebia) badouwanica nom. nov.; NIGP126379 (93-HE-2K1，2) for Protorthophlebia (Protorthophlebia) karamayiensis nom. nov.; another specimen NIGP126376 (92-T-22/K3) is considered that it is not Protorthophlebia latipennis Tillyard,1933, and should be assigned to a new genus and new species for Junggarochorista tuzigouensis, Hong, 2009, and can be transferred to family Parachoristidae Tillyard, 1937. The main features of above revised genera and species are redescribed in this paper. According to the record of H C Zhang's original paper above 4 specimens are deposited in Nanjing Inst. Geol. Palaeont., Acad. Sin., Nanjing City, 210008, China.
