Lock, Koen, 2011, Fifty leafhoppers new to Belgium (Hemiptera: Cicadellidae), Belgian Journal of Entomology 88, pp. 1-28 : 1-28

Edwardsiana lamellaris (Ribaut, 1931)

The outer pair of appendages of the aedeagus is thin and short, the inner appendages are broadened and forked at their base, while the shaft is strongly broadened in lateral view ( Fig. 18 ). In dry, warm habitats on Rosa spp. V-X (RIBAUT, 1936).

MATERIAL EXAMINED: Rochefort, Maupas (50.110, 5.209), 16.IX.2018.

Edwardsiana platanicola (Vidano, 1961)

The outer pair of appendages of the aedeagus is short and directed slightly upwards, the inner appendages are forked halfway and the lower branch forms a right angle with the shaft as well as the outer appendages, while the upper branch is directed upwards at an angle of about 45° with the lower branch ( Fig. 19) ( DELLA GIUSTINA, 1989). This species was recently also found in the Grand Duchy of Luxembourg ( LOCK & VAN BUTSEL, unpublished data). On Platanus x hispanica Miller ex Münchh. ( DELLA GIUSTINA, 1989). IV-X (MÜHLETHALER et al., 2018).

MATERIAL EXAMINED: Brugge, centre (51.212, 3.210), 19.X.2018.

Edwardsiana tersa (Edwards, 1914)

The outer pair of appendages of the aedeagus is short and directed slightly forwards and upwards, the inner appendages are forked close to the base, while the first half of the shaft is broadened in lateral view ( Fig. 20 ). On Salix viminalis L., mostly along running water. V-IX.

MATERIAL EXAMINED: Dilsen-Stokkem, Kerkeweerd (51.025, 5.751), 2.IX.2017.

Eupterycyba jucunda (Herrich-Schäffer, 1837)

In this very distinctive species, the pronotum has two lateral round spots, a rhomboidal central spot and often two lateral spots on the front edge ( Fig. 21). The prominent markings on the scutellum and dark streaks on the forewings are to some extent variable and may sometimes be almost completely absent. The yellow and black-banded nymph is equally striking and easily recognisable (STÖCKMANN et al., 2013). Near water or in moist areas on Alnus glutinosa (L.) Gaertn. VII-X. The species was marked as expected by COUBEAUX (1892a).

MATERIAL EXAMINED: Berg , Torfbroek (50.927, 4.542), 15.VII.2018 ; Stekene , Steengelaag (51.204, 4.050), 21.VII.2018 ; Brugge , Blauwe Toren (51.260, 3.195), 1.VIII.2018 ; Neerpelt , Hageven (51.252, 5.415), 4.VIII.2018 ; Gentbrugge , Arbedpark (51.046, 3.751), 16.VIII.2018 ; Frasnes-les-Anvaing , Bois de Leuze (50.699, 3.640), 8.IX.2018 .
