Itaphlebia Hong, 2007, syn. n. (partim, quoad Itaphlebia tongchuanensis ) Type species. Mesopsyche triareolata Tillyard, 1917; Upper Triassic, Australia. Diagnosis. Forewing relatively broad. SC rather long, with single or multiple fore branches. Costal space typically expanded. Both RS and MA forks not longer than their stems. MP 4-branched. CuA base from transverse to distinctly inclined backwards, usually situated much more distally than MP origin. Crossvein cua-cup of same inclination as CuA base. Intercubital space rather expanded. Crossveins not numerous, their arrangement rather stable. In hindwing, CuP convex with respect to membrane; fused with A1 very close to base. Comparison. Differs from Permopsyche by the base of CuA being inclined backwards, costal space widened, and hindwing CuP convex. Composition. In addition to the type species, from the beds near the Permian-Triassic boundary of Kuznetsk Basin, Mesopsyche javorskii (Zalessky, 1935) comb. n.; from the Middle Triassic of China, Mesopsyche tongchuanensis (Hong, 2007) comb. n.; from the Middle-Upper Triassic Madygen Formation of Kyrgyzstan, Mesopsyche shcherbakovi , Mesopsyche justa , Mesopsyche ordinata , Mesopsyche tortiva , and Mesopsyche gentica ( Novokshonov 1997c , Novokshonov and Sukatcheva 2001 ); from the Upper Triassic of South Africa, Mesopsyche optata (Riek, 1976), Mesopsyche magna (Riek, 1976); from the Upper Triassic of Ukraine, Mesopsyche dobrokhotovae ( Novokshonov 1997c ).
