Emended description. Head process long (longer in females than in males), of nearly same width throughout its length, sometimes slightly enlarged apically (in lateral view), compressed, with median carina ventrally (Figs 1B, 4A–C, 5D–E, 6, 7C–G). Laterofrontal sutures not extended beyond antennal base. Lora elongate oval, reaching genal margins ventrally. Ocelli present. Pronotum with median carina. Forewing with reticulate venation, clavus long, 3/4 as long as forewing, appendix reduced. Hind wings well developped, nearly as long as forewings, with well developed appendage (Fig. 6A). Hind femur distal macrosetae 2 + 0. Hind tibia laterally flattened. Ovipositor slightly protruding beyond hind margins of pygofer in lateral view.
Male terminalia (Fig. 8). Apodemes of abdominal sternites I–II small and short (Fig. 8I–J). Apodemes of abdominal tergite II large, nearly reaching tergite hind margin (Fig. 8K). Pygofer elongate, nearly triangular in lateral view, with long and narrow sclerotization below dorsal margins (dotted line on fig. 8A), deeply concaved above subgenital plates (Fig. 8A). Subgenital plates long, narrowing apically (in ventral view) (Fig. 8B). Connective large, elongate and flat (Fig. 8E–F). Style with two processes (lobes)—one with an elongate capitulum bearing small semicircular subapical lobe and another ending with a tooth (Fig. 8 G–H). Aedeagus with wide base and pair of long and narrow basal processes laterally (Fig. 8C–D), Aedeagal shaft flattened dorso-ventrally, strongly curved (in lateral view), with serrated lateral margins and basal part ventrally. Gonopore apical.
Female terminalia. Female sternite VII with deep median notch on hind margin (Fig. 9B).
Type material examined. Lectotype of Adelungia breviceps, ♁ (here designated), “Zakaspij [hand written in ink] / Uch. Adzha [hand written in ink] / 1929 [hand written in ink] / A. Shestakov [hand written in ink]” // Adelungia [hand written in ink] / breviceps m. typus [hand written in ink] / V. Kusnezov det. [print] 1931 [hand written in ink]”. Paralectotypes of Adelungia breviceps: 1♁, 1♀, “Zakaspij [hand written in ink] / Uch. Adzha [hand written in ink] / 1929 [hand written in ink] / A. Shestakov [hand written in ink]” // “c. V. Kusnezov [print]”. All specimens are marked by the golden paper circle.
Other material examined. Kazakhstan: 12♁, 12♀, Karagandinskaya Oblast’, 150 km NW Betpak-Dala, Kense meteorological station, 10. VI.1961, on Calligonum, A.F. Emeljanov leg. Uzbekistan: 7♁, 4♀, S Dzhar-Kurgan, 18.IV.1962, on Calligonum, E.L. Gurjeva leg.; 1♁, Kyzylkum, Zhamansky tract, 19.VIII.1970, M.I. Falkovich leg. Turkmenistan: 1♀, Merv, 5. VI.1905, T. Sumakov leg.; 1♀, 3 km N Tashkepri, 18. V.1954, V. I. Tobias leg.; 2♁, 2♀, Repetek, 4–5. V.1955, V. I. Tobias leg.; 2♀, Dzhebel, 18. V.1969, V. Ph. Zajtsev leg.
Note. Different populations of S. calligoni throughout its range have some differences in head length and females always have longer heads than males in the same population (Figs 6, 7), however, the male genitalia structure is rather uniform among these populations. Thus A. tridigitata Dlabola, 1984 having the same structure of the aedeagus (Dlabola 1984, fig. 38) as S. calligoni is treated as a junior synonym of S. calligoni.
