| Popis: | Archizelmira jarzembowskii sp. nov. (Fig. 1) Material. Holotype PIN 1255 /2218, isolated wing, housed at Borissiak Paleontological Institute, Russian Academy of Sciences, Moscow, Russia. Etymology. The species epithet honors Dr. Edmund Jarzembowski to acknowledge his contribution to the study of extinct Insecta. Diagnosis. Tiny round wing with pterostigma, Rs base almost transverse, R 5 longer than distal section of R 4+5, anal lobe reduced. Locality and horizon. Kubekovo village on the left bank of the Yenisey River (56.15°N, 93.13°E), Emeliyanovo district, Krasnoyarsk Krai, Central Siberia, Russia; Upper Itat subformation of the Itat Formation (Bathonian; Middle Jurassic). Description. Wing small, round, wing length, 2.2 mm; wing maximal width, 1.1 mm. Pterostigma elongate and narrow; Rs base almost transverse, R 4 subequal to r-m, R 5 longer than distal section of R 4+5; anal lobe and alula not developed. Remarks. The new species is the smallest in the genus, differing from the two other species also in the presence of the pterostigma and the absence of the anal lobe (unique characters of unclear polarity in the genus as well as in the family).
