Scopesus Sziladyi KISS , 1924 Holotype : ( ♀ ) Zengg 909.VII.13 (Budapest), examined and synonymized by HORSTMANN (2007: 319) . D e s c r i p t i o n: ♀ . Body length 8.5–9.0 mm.

Temple distinctly and roundly narrowed behind eye. Ocelli large, OED 1.0× ocellar diameter. Face granulated, dull. Clypeus moderately convex, not bulging medially, with sparse punctures; apical margin with short lateral extensions, almost straight. Mandibular teeth equally sized, sometimes ventral tooth slightly larger than dorsal tooth. MI 0.5. Mesoscutum finely granulate, dull. Notaulus ± distinct in frontal 0.5 of mesoscutum.

Nervellus of hind wing slightly inclivous, intercepted in its apical 0.7. 1 st tergite slender, 2.2× as long as wide, without latero-median carina. 2 nd tergite 1.1× as wide as long. Color: black. Antenna yellowish. Palps, mandible except teeth, clypeus, face (except small dorso-median brown spot), large hook-shaped anterolateral spot on mesoscutum, hind edge of pronotum, tegula, subtegular ridge, mesepisternum, scutellum and postscutellum yellow. 1 st tergite apically, 2 nd tergite except two paramedian brown spots and 3 rd to 4 th tergites entirely red. Fore and mid coxae, all trochanters and trochantelli reddish-yellow; hind coxa red; legs otherwise red; hind tibia yellowish, reddish-brown in apical 0.1; hind tarsus ochreous. Pterostigma yellow. ♁. Body length 8.0– 8.5 mm . Flagellum with 39–42 segments, slender; 1 st flagellar segment 5.0–5.3× as long as wide and 1.5–1.6× as long as 2 nd segment; 2 nd segment 3.0– 3.3×, 3 rd segment 2.5–2.8× and preapical segment c 2.0× as long as wide. Temple moderately and roundly narrowed behind eye. Ocelli large, OED 1.1–1.2× ocellar diameter. Clypeus moderately convex, not bulging medially, with sparse punctures; apical margin with short lateral extensions. Mandibular teeth equally sized. MI 0.3. Mesopleuron granulate, without punctures, dull; sometimes with few fine irregular striae dorsally. Speculum with microsculpture, shining. Legs slender; hind femur 4.9–5.3× as long as wide. Propodeum granulated. Area superomedia with fine almost parallel lateral carinae. Area petiolaris with complete carina. Areolet in fore wing closed, e. g. vein 3rsm present but unpigmented. Vein 2m-cu reaching areolet close to vein 3rs-m. Vein 1cu-a postfurcal by 2× its width. 1 st tergite 1.8–2.2× as long as wide, without latero-median carina. 2 nd tergite 1.0–1.1× as wide as long. Color: black. Antenna yellowish. Palps, mandible except teeth, clypeus, face, malar space, collar, large hook-shaped anterolateral spot on mesoscutum, ventral and hind edge of pronotum, tegula, subtegular ridge, mesepisternum, scutellum and postscutellum yellow. 1 st tergite apically, 2 nd tergite except large basal brown spot, 3 rd tergite entirely and 4 th to 5 th tergites ± red. Fore and mid coxae, all trochanters and trochantelli yellowish; hind coxa red; legs otherwise red; hind tibia yellowish, infuscate in apical 0.2; hind tarsus brownish or ochreous. Pterostigma yellowish. Host: Aglaostigma aucupariae ( KLUG , 1817) (Hym., Tenthredinidae ) ( ZSM ). D i s t r i b u t i o n: West Palaearctic, studied material from Germany . Taxonomical remarks: This species was transferred to the genus Scopesis by HORSTMANN (2007) with question mark. He noted that the equally sized teeth speak against an inclusion into the genus Alcochera FÖRSTER , but the relation of the basal two flagellomeres, presence of vein 3rs-m in fore wing and color pattern argue against the genus Scopesis and fit better with Alcochera . We transfer this species to Alcochera here.
