Diagnosis. Metope wide, distinctly enlarged below eyes, convex (its upper part well visible from above), smooth, without carinae. Coryphe transverse, 3–4 times as wide as long at midline. Forewing radius and media stems running parallel and closely from the basal cell to wing middle. Hind tibia with a single lateral spine. Lateral margins of male anal tube without processes (in lateral view). Phallobase basement with short lobe-shaped processes. Ventral aedeagal hooks circularly curved. Style with deeply concave hind margin and with a strong comb under the capitulum; capitulum on long neck. Generally staw yellow. Total length males — 3.0–3.4 mm, females—3.8 mm.

Supplementary description. Metope convex (its upper part well visible from above), without carinae, enlarged below eyes and narrowed to clypeus, its lateral margins hang over the pedicels ( Figs 8 View FIGURES 6–8 , 30 View FIGURES 30–31 ). Metopoclypeal suture steeply wedge-shaped. Coryphe flat, transverse, 3–4 times as wide as long at midline, with weak median groove; anterior margin weakly and widely convex; posterior margin concave ( Figs 6 View FIGURES 6–8 , 31 View FIGURES 30–31 ). Pronotum slightly longer than coryphe medially, without carinae. Mesonotum 1.5 times as long as pronotum medially, without carinae. Forewings with distinct knee prominence. Forewing vein sequence ( Fig. 7 View FIGURES 6–8 ): R 2, furcating in basal third of the wing; M 4–6, firstly furcating near to wing middle, M 1 and M 2 furcating in apical third of the wing; CuA 1 (in one male examined CuA 2 furcating on its one wing). Radius and media running parallel and closely in basal third of the wing. Radius furcating before media. Hind tibiae with a single lateral spine and 8–10 apical spines. First metatarsomere with 6–7 intermediate spines.

Coloration. General coloration straw yellow. Metopoclypeal suture black. Post- and anteclypeus sometimes brown frontally and laterally. Rostrum brown to dark brown or black, with black apex. Antennal flagellum black. Legs sometimes light brown. Claws brown to dark brown. Apices of leg spines dark brown or black. Abdominal tergites brown to dark brown or black.

Male genitalia ( Figs 32–38 View FIGURES 32–38 ). Anal tube elongately oval, twice as long as wide medially, with widely rounded apex (in dorsal view) ( Fig. 37 View FIGURES 32–38 ). Lateral margins of anal tube turned downwards, without processes ( Fig. 38 View FIGURES 32–38 ). Anal column ⅓ of anal tube. Lobe-shaped processes of phallobase basement short, rounded ( Fig. 34 View FIGURES 32–38 ). Ventral phallobase lobe without apical notch ( Fig. 33 View FIGURES 32–38 ). Ventral aedeagal hooks circularly curved. Style with deeply concave hind margin, caudo-dorsal angle widely rounded ( Fig. 35 View FIGURES 32–38 ). Style margin under the capitulum with a strong comb. Capitulum of style on long neck, narrowing apically (in dorsal view) ( Fig. 36 View FIGURES 32–38 ).

Female genitalia ( Figs 67, 68 View FIGURES 64–70 , 71–75 View FIGURES 71–77 ). Hind margin of sternite VII with short labial median process (in dorsal view) ( Fig. 67 View FIGURES 64–70 , shaded). Anal tube long and convex (in lateral view), 3.5 times as long as wide medially, narrowing apically, with rounded apex (in dorsal view) ( Fig. 71 View FIGURES 71–77 ). Anal column wide and short, ¹⁄ of anal tube. Anterior connective lamina of gonapophysis VIII with four teeth in lateral group ( Fig. 74 View FIGURES 71–77 ).

Type material examined. Algeria: ♂, paralectotype, “ Tiaret [hand written] // collection / E. de Bergevin [print] // TYPE [print] // Paralecto- / typus [print] // Hysteropterum / juniperi / Bergev. [hand written]” ( MNHN) .

Other material examined. Morocco: 8♂, 4♀ , “ Maroc Or. / Aïn Kerma (30 km Sud Est Oujda) / 5.V.1984 / M. Beylac rec.” ( MNHN and ZIN) .

Notes. The species was described from Tiaret in central north Algeria and the type series was collected from Juniperus oxycedrus L. ( Cupressaceae ) at 1100 m. a.s.l. ( Bergevin 1915). Additional material listed above is from the Oriental Region of northeastern Morocco near to the border with Algeria which is first record of this species from the country.
