Introduction

This dark species with pale tegmina and carinae is known from a number of widely separated localities in New South Wales. Three specimens at two localitites have been collected from species of Senecio L. (Asteraceae) but whether this is an indication of host association is unknown.

Diagnosis

Colour. Vertex light brown apart from mid to dark brown disc of apical compartment of vertex and dark apical carina. Face mid to dark brown with pale carinae. Pronotum light brown; mesonotum mid to dark brown. Forewing hyaline colourless with a few light brown marks; pterostigma and area apical of pterostigma whitish followed by a mid to dark brown area around R and MA; veins and tubercles concolorous with cells. Legs light to mid brown. Abdominal sternites mid to dark brown. Morphology. Body length: ♂ 4.4–4.8 mm, ♀ 5.0–5.4 mm. Head: Vertex 1.7–1.8× wider than long; at level of basal emargination 1.3–1.4× wider than at subapical carina; apical and subapical carina v-shaped; median carina of vertex absent; basal compartment of vertex 3.2–3.8× longer than apical compartment. Frons about 1.2× longer than wide; frons just not visible in dorsal view. Position of maximum width of frons more or less around centre of frontoclypeal suture. Frontoclypeal suture semicircular, bent upwards. Rostrum surpassing hind coxae; apical segment of rostrum almost as long as subapical segment. Thorax: Pronotum slightly to moderately wider than head (including eyes). Hind margin of pronotum acutely angled or rectangular. Forewing 3.7–4.1× longer than wide; forewing with well-developed basal emargination; costa with about 31–37 tubercles, tubercles concolorous with veins; Sc+R+M near basal cell fused, forming a moderate-to-long (at least half of length of basal cell) common stem Sc+R+M; fork of ScRA+RP moderately to distinctly basad of fork CuA1+CuA2; position of r-m distad of fork MA+MP; transverse veinlet M3+4 to Cu1a inserting at M3+4 at same level or distad of r-m; position of icu at CuA at same level as apex of clavus; position of icu at CuP more or less at same level as apex of clavus; RP apically trifid; MA apically trifid; additional subapical cell between branches ofMAabsent; nodus of y-vein slightly basad of centre of clavus; vein delimiting subapical cell C4 distinctly distad of vein delimiting C5; 10 apical cells. Hind leg: 1st and 2nd tarsomere with 7 apical teeth. Male genitalia: Anal tube more or less symmetrical in dorsal and caudal view; lateral lobe triangular in lateral view. Ventromedian process of pygofer triangular, margin slightly darker. Aedeagus: Phallotheca right lateral with very long, thick spine (a), bearing two little spines (b,c). Little spines very slender, facing opposite directions. Phallotheca ventrally with a sclerotised ridge bearing a pair of minute spines (d). Flagellum sclerotised, unarmed (Löcker 2014).
