Sogjuta Martynova, 1958

( Fig. 17 )

Type species. Sogjuta speciosa Martynova, 1958: 77 (by original designation).

Diagnosis. Forewing ovoid, relatively small and rounded apically; costal area relatively narrow along entire length, subcostal veinlets mostly simple, widely spaced along entire wing; RP with 8–9 branches; RP1 originated relatively far from origin of RP; M forked basal to origin of RP1; MA and MP distally dichotomously branched; crossveins in radial to mediocubital spaces arranged in three regular gradate series; CuA with few pectinate branches (2–4); CuP pectinately branched (4–5); HW unknown.

Comments. Martynova (1958) originally placed Sogjuta in Nymphitidae and was later moved to Osmylidae by Lambkin (1988). Khramov (2011) described a second species and characterised the genus further. The small size and rounded shape of the forewing, along with the branching pattern of the medial and cubital veins supports placement in Mesosmylininae ( Khramov, 2011; Makarkin et al., 2014). Three gradate series in the forewing separates Sogjuta from Mesosmylina , which has 5–6 gradates.
