039887B5FFAB1940FF4BFE32C3BBFB45.taxon	discussion	Remarks. Recently the diagnosis of the tribe Asynaptini was revised following analysis of the monotypic genus Guyasutomyia Plakidas, 2023 (Plakidas 2023). We update this by including the following characters of the female of Vladimiretskia nathani Fedotova et Perkovsky, gen. et sp. nov. described below. These include: eyes holoptic, almost completely covering the head without an eye bridge (figs 2 a, 3 i); antennae with 16 flagellomeres that possess a short neck and circumfilar sensoria (figs 1 a, 3 b, c); very short mouth parts and palpi; a wide head, unsclerotized costal cell, short straight vein R 5 not reaching wing apex; simple CuA and M 4; and the absence of r-m (figs 1 a, 3 a). The female abdomen is telescopic from segments 6 – 8, with an immobile 9 th segment. The cerci are separate with 3 - segmented dorsal lamellae (figs 1 a, e). Previously, the collective tribe Asynaptini (167 species, 18 genera), was not divided into subtribes (Panelius 1965; Parnell 1971; Fedotova & Sidorenko 2007; Jaschhof & Jaschhof 2013, 2023; Gagné & Jaschhof 2021; Plakidas 2023). Asynaptini genera are extremely diverse in eye shape, width of the ocular bridge, the structure of palpi, wing venation, and male and female genitalia. However, all genera of Asynaptini have an increased number of flagellomeres (more than 14), a characteristic bend of rs, have the crossvein r-m, the curved R 5 fuses with C before or behind the wing apex, and CuA and M 4 are present, simple, well-developed, and reach the edge of the wing. Female Asynaptini are little known. Most species were collected in various traps, and as females of closely related species and genera are very similar, species have been described primarily by males if the adults were not reared from larvae.	en	Fedotova, Zoya A., Vasilenko, Dmitry V., Perkovsky, Evgeny E.

039887B5FFAB1941FF4BFACAC3D9FE99.taxon	diagnosis	Diagnosis. Female head: broad; eyes very large, located dorso-laterally. Eyes completely fused at occiput. Рalpi 3 - segmented with round dark palpiger (figs. 1 b, c; 2 a; 3 d), much shorter than half height and length of head. Antennae more than 2 + 14 segmented, flagellomeres with distal neck. Basal node of flagellomeres with well-developed circumfilar sensoria. Vein R 5 almost straight, joining C before wing apex, margin of wing interrupted at this point; cell between C, R 1 not sclerotized. R 1 completely fused proximally with R 5; rs absent; r-m strongly curved distally near joining R 1 (figs 1 a, 3 a); CuA and M 4 simple, well developed from base to end. All legs densely covered by setae. Abdomen without swollen tergites and sternites or long setae. Ovipositor lamellae short, with 3 - segmented lamellae. Tenth abdominal sternite does not protrude on ventral ovipositor. Abdomen apically curved upward (figs. 1 a, e; 2 d). Comparison. The new subtribe strongly differs from Asynaptina sensu lato and others of subfamily Porricondylinae s. str. and Winnertziinae s. str. by its straight R 5 joining C before the wing apex and absence rs, and differs from Winnertziinae by its unsclerotized costal cell and flagellomere sensorial filae not multiporous or uniporous. It is similar to the latter by: simple CuA and M 4; cerci with 3 - segmented lamellae as in Diallactiini and Winnerziinae s. l.; upward curved ovipositor apex as in other Asynaptina s. str. and in Winnertziinae; more than 14 flagellomeres as only in subtribe Asynaptina s. str.; and palpi shorter than half height and length of head like some rare Asynaptina s. str. genera and in different tribes of Porricondylinae s. l. and Winnertziinae s. l. Very short palpi among Asynaptini s. l. are known only in the monotypical genera Asycola Spungis, 1991 and Guyasutomyia Plakidas, 2023 (Spungis, 1991; Plakidas, 2023). The new subtribe additionally differs from Asynaptina by large completely fused eyes; distally well-developed CuA and M 4; smallest palpi length; and cerci with 3 - segmented lamellae (not 2 - segmented).	en	Fedotova, Zoya A., Vasilenko, Dmitry V., Perkovsky, Evgeny E.
