Scopesis areolaris ( PFANKUCH, 1921) (figs 19, 91)

Holotype: (♁) Crefeld 14.6.10 Puhlmann; Type ♁; Scopesis areolaris PFANK. ♁ (Berlin), type examined. D e s c r i p t i o n: ♁. Body length 9 mm. Flagellum with 40 flagellomeres; 1st

flagellar segment 6.0× as long as wide and 1.8× as long as 2 nd segment; 2 nd segment 3.3× and 3 rd segment 2.8× as long as wide, preapical segment c 2× as long as wide. Temple moderately and roundly narrowed behind eye. OED 1.4× ocellar diameter. Face granulated and with superficial punctures, dull. Clypeus distinctly convex, slightly bulging medially, with coarse dense punctures and some long setae; apical margin slightly rounded, with very small flat extensions laterally. Mandibular teeth of equal size.

Mesoscutum finely granulate, ± shining. Notaulus impressed in frontal 0.3 of mesoscutum. Mesopleuron granulate and superficially punctate, with rather strong striae dorsally, dull. Speculum with microsculpture, ± shining. Area superomedia with incomplete divergent lateral carinae. Area petiolaris with complete carina. Lateral longitudinal carina of propodeum weak and partly obsolete; pleural carina distinct and complete. Hind femur 4.7× as long as wide. Inner apical spur of hind tibia 0.65× as long as hind metatarsus. Vein 2rs-m 0.9× as long as vein M between 2rs-m and 2m-cu. Vein 1cu-a postfurcal by 2× its width. Nervellus of hind wing inclivous, intercepted in its apical 0.7. 1 st tergite 2.0× as long as wide, without latero-median carina. 2 nd tergite 1.2× as wide as long.

Color: black. Scape ventrally and flagellum reddish, basal flagellomeres blackish dorsally. Palps partly, mandible except teeth, clypeus, facial orbit and two paramedian dorsal spots on face yellowish. Tegula reddish-brown, subtegular ridge reddish. Apical 0.2 of 1 st tergite, 2 nd to 4 th tergites entirely and 5 th tergite dorsally red, laterally black. Coxae and trochanters blackish. Trochantelli reddish; legs otherwise red; hind femur red, black in apical 0.1; hind tibia yellowish, black in apical 0.4; hind tarsus black. Pterostigma chestnut-brown.

♀ and hosts unknown.

D i s t r i b u t i o n: Only known from the German holotype.

T a x o n o m i c a l r e m a r k: This species belongs to Scopesis (e. g. typical length of 1 st and 2 nd flagellar segments, form of areolet and structure of 1 st tergite) but is characterized by its unique facial color pattern and unusual structure of the clypeus which resembles Cuboscopesis fraternus (HOLMGREN). We did not find any ♀♀ with this form of clypeus in the studied Scopesis material, the ♀ of Sc. areolaris remains unknown.
