Introduction

The presence of this Holarctic species in Australia was first reported by Fletcher & Knight (1998). Its host is Betula species and its Australian distribution is recorded as the Southeast Highlands of New South Wales and Victoria but this is presumed to be limited by the absence of any survey of birch trees across southern Australia. It is also present in the South Island of New Zealand. It causes speckling damage to the leaves.

Ecological Descriptors

All stages: parenchyma feeder (associated flora: Betula spp. [BETULACEAE]).

Diagnosis

Length and colouring as in [Empoasca] smaragdula [(Fallén)]. Appendages of the anal tube approximately as those of smaragdula. Aedeagus: the lateral lobes are longer and obliquely directed dorsally, not parallel with the median part as in smaragdula. In the ventral view the lateral lobes lie much nearer the median part than in smaragdula. The female similar to the corresponding sex of smaragdula (Linnavuori 1951).

Coloration. Adult: Face greenish; commissural border of fore wing concolorous; corioclaval suture black or fuscous. Nymph: Light green, almost without any markings, only posterior margins of abdominal tergites brown. Sexual characters. Male: Aedeagus with parallel sided processes, in lateral view parallel to main stem; length of processes shorter than stem; basis of processes close to each other. Pygofer process in male apically slender. Process of anal collar short and stout. Length of apodemes of sternite VII twice as long as broad or as long as broad; phragma lobes of tergite III as long as broad or shorter than broad. Female: Sternite VII with prolongated lobe; base of first valvifer in ventral view broad and irregularly rounded with a median ridge, distally straight; apex of median valvula bearing 6–10 teeth; structure of teeth irregular coarse; ventral edge of valvula apically strongly curved. Body length. Male 4.2–4.4 mm; female 4.6–4.8 mm; nymph 2.9 mm (Mühlethaler 2009).
