Description. Structure. Vertex triangularly elongate, with tiny median groove, nearly twice as long as wide between the eyes, with rounded apex (in dorsal view) ( Figs 1, 3 View Figs 1–4 ). Frons and vertex joint at acute angle (in lateral view) ( Figs 2, 4 View Figs 1–4 ). Rostrum short, apical segment cylindrical. Pronotum half as long as vertex at midline. Mesonotum slightly shorter than pronotum, with transverse groove. Forewings reaching hind margin of 7th tergite, with clavus 3/4 as long as whole wing. Forewings with reduced membrane, venation smooth. Hind wings not visible, apparently rudimentary. Hind femora with 2 + 1 + 1 apical spines. eral view, 14 = right lobe of pygofer, dorsal view

Colouration. General colouration light yellow whit- ish ( Figs 1–4 View Figs 1–4 ). Frons darkened, except below its upper margin, with transverse yellow stripes besides of median line. Gena with wide brown cross band below the eye. Vertex with three pairs of large brown to dark brown comma-shaped spots – apical spots fused below apex of vertex and two pairs of spots behind are separated me- dially; median line dark brown Figs 15–16. Stirellus desertus sp. n., paratype, female between the spots ( Figs 1, 3 View Figs 1–4 ). genitalia: 15 = ovipositor, lateral view, 16 = sternum VII, Rostrum dark brown apically. ventral view Pronotum with light brown an- terior margin, with 10 (3 + 2 + 2 + 3) brown to dark brown spots along the margin, and with transverse light brown stripe along posterior margin. Mesonotum with transverse dark brown stripe below the groove separating scutellum and with two brown spots below an- terior margin. Fore wings with cells margined by brown stripes inside. Thorax from below and coxae anteriorly dark brown. Tibiae with dark brown dots at the bases of macrosetae. Inner margins of hind femora dark brown in a female. Apices of tarsomeres and claws from brown to dark brown. Abdominal sternites dark brown laterally. Laterotergites III dark brown almost completely. Laterotergites IV–VII partly dark brown and yellowish. Female abdominal tergites with dark brown median stripe. Female pygofer with elongate brown stripe laterally and with dark brown spot subapically on each side ( Figs 4 View Figs 1–4 , 15).

Male genitalia ( Figs 5–14 View Figs 5–14 ). Anal tube elongately cylindrical ( Figs 12, 13 View Figs 5–14 ). Pygofer lobe with caudal margin at obtuse angle ( Fig. 7 View Figs 5–14 ), without lateral tooth, but with a subapical swelling visible only in dorsal view ( Fig. 14 View Figs 5–14 ). Subgenital plates as long as pygofer lobes in lateral view, with macrosetae on lateral margines and with a tooth on the inner lobe cover- ing style ( Figs 8–10 View Figs 5–14 ). Genital valve large, triangular-shaped ( Figs 8, 10 View Figs 5–14 ). Connective with a stem as long as the arms ( Fig. 6 View Figs 5–14 ). Style with four subapical teeth ( Fig. 11 View Figs 5–14 ). Aedeagus with long S-shaped shaft, twice as long as aedeagal basement (in lateral view) ( Fig. 5 View Figs 5–14 ).

Female genitalia (Figs 15, 16). Ovipositor protruding far beyond the pygofer apex (Fig. 15). Hind margin of sternum VII deeply concave medially (Fig. 16).

Total length. Male – 3.0 mm. Female – 5.0 mm.

Etymology. The species name refers to the type of biotope where it was collected – sand desert.
