FE09E473F833FFA6FF11F85DFEE5FD12.taxon	diagnosis	Diagnosis. Forewings are unusually narrow, 5 times as long as wide. SC long, considerably longer than half the wing length, close to the anterior margin of the wing; c-sc very short. There are three crossveins in the costal field; in the pterostigmal region there is one oblique crossvein. RS is two-branched, divided distally to double r-rs crossveins. M two-branched, divided in the middle of the wing, CuA comb-shaped posteriorly in the distal part. Simple CuP short, A 1 simple, straight, A 2 two-branched with a convex anterior branch.	en	Sinitshenkova, Nina D., Yan, Evgeny V.

FE09E473F833FFA6FF11F85DFEE5FD12.taxon	discussion	Remarks. The new genus is assigned to the family Palaeonemouridae due to having a straight anterior margin of the forewing, the presence of a narrow costal area with transverse veins, a long SC significantly longer than half the length of the wing, the presence of an oblique transverse vein in the pterostigmal region, the junction of R and M near the wing base, two-branched RS and M, and a short CuP. Comparison. Vyazonemoura gen. nov. differs from other genera in the family by having narrow forewings. The comb-shaped CuA of the new genus is similar to the Triassic Cristonemoura Sinitshenkova, 1987, belonging to the family Perlariopseidae Sinitshenkova, 1985, from which it is clearly distinguished by the presence of two transverse r-rs crossveins, the absence of a long branch extending anteriorly from CuA, and a shorter CuP.	en	Sinitshenkova, Nina D., Yan, Evgeny V.

FE09E473F830FFA7FF11FCFAFF14FD12.taxon	description	Description. Length of forewing (holotype): 6.5 mm; its greatest width: 1.3 mm. The costal field of the forewing is very narrow, within which at least three crossveins can be distinguished. The oblique crossvein in the pterostigmal region is located in the apical quarter of the wing. SC is slightly curved at the base and flows into R in the distal third of the wing length; c-sc flows into C noticeably basal to the apex of SC. RS departs from R in the basal quarter of the wing length; there are two r-rs crossveins. The distal r-rs departs from R basal to the apex of SC, and the second flows into RS basal to rs-m. The petiole of RS is three times shorter than its branches; rs-m departs from RS basal to r-rs and flows into MA noticeably distal to the M fork; m-cu departs from MP distal to the fork of M and flows into CuA basal to its first fork; in the medial field there are four crossveins. CuA is pectinate posteriorly with four short branches. CuP is short and flows into the wing margin distal to the point of departure of RS from R.	en	Sinitshenkova, Nina D., Yan, Evgeny V.

FE09E473F830FFA7FF11FCFAFF14FD12.taxon	discussion	Remarks. The unusual proportions of the V. storozhenkoi ’ s wing — very narrow relative to its length — suggest that it was deformed after burial by sediment movement. Such phenomena are observed in some localities. The strong distortion of wing proportions is especially pronounced at the Dzhayloucho locality, Kyrgyzstan, where the Madygen Formation deposits are dated to the Middle-Upper Triassic. Stretching of the wings in different directions is noted in stoneflies (Sinitshenkova 1987), in hymenoptera Symphyta (Rasnitsyn 1969: 10), and in beetles (Ponomarenko 1969: 5 – 7). The deformation of fossil insects at Dzhayloucho is apparently due to compression and stretching of the host rock. In Vyazovka, no similar deformation was noted for any remains of stoneflies, dragonflies (Felker 2020), mecopterans (Bashkuev 2022), or caddisflies (Sukatsheva & Sinitshenkova 2025) described from here; apparently, there is no reason to assume a distortion of the natural dimensions of the wing of V. storozhenkoi gen. et sp. nov.	en	Sinitshenkova, Nina D., Yan, Evgeny V.
