1. (a) Terga mainly green, usually on both sides with (sometimes fused) two black spots (rarely without these spots); anterior margins of the terga narrowly black, these margins usually visible through the translucent hind margin of the previous tergite
(Figs 3a, b) (in Fennoscandian specimens this is more distinct than in more southern specimens; in Fennoscandian specimens frequently also sternites
with distinct black marked anterior margins).
(b) Postocellar area green, only the surrounding furrows mainly black (Fig. 4a) (in eastern European specimens sometimes lateral furrows completely green).
(c) Black color of the upper head forming a ‘ω’: frontal ridges green, frontal field and frons between antennal furrow and inner eye margin largely black, the black parts not fused above the antennal sockets (Fig. 4a).
(d) Upper head usually with distinct, rather mat microsculpture
(e) Plantar lobes (“pulvilli
”) small, distance between 1st and 2nd in ♂ 2.6–3.2 ×, in ♀ 1.6–2.0 × as long as its own length (Fig. 3g).
(f) Penis valve as in Figs 6e, l.
(g) Saw similar to scalaris, but serrulae somewhat smaller (Fig. 5h).
(h) Median mesoscutal lobes mainly green, only median groove and notaulus
more or less black (Figs 3a, b).
Morphology : Body size in Fennoscandia ♂ 6.5–8 mm, ♀ 7–9 mm, specimens from other parts of Europe up to 12 mm. Meso- and metascutellum with very weak microsculpture, shiny, mesocutellar appendage smooth and shiny. Mesoscutellum flat or slightly convex. Temples with microsculpture, usually rather mat. Postocellar area variable in size, about 2.2–2.8 times as broad as long, convex, laterally with deep, converging furrows; anteriorly blunt triangular, with sharp, but less deep furrow. Color pattern of head and thorax
varies little. Postocellar area always green with black furrows. Occiput
mainly black, only green close to the occipital carina. Distribution : Europe (not recorded from Portugal), also eastern Palaearctic.
