SUPPLEMENTARY DESCRIPTION. Metope wide and flat, enlarged above clypeus (below the eyes) ( Fig. 20 ); lateral margins roof-shapedly cover pedicel.

Metope with distinct median carina running from its straight upper margin to metopoclypeal suture; sublateral carinae very weak, not joint with median carina on upper margin of metope. Metopoclypeal suture convex. Clypeus without carinae;

lateral margins nearly straight. Coryphe transverse, nearly 10 times as wide as long medially, without carinae; anterior margin weakly convex; posterior margin deeply concave ( Fig. 21 ). Coryphe and metope joint at right angle (in lateral view) ( Fig. 22 ).

Ocelli absent. Pedicel shortly cylindrical. Pronotum with median carina and a row of sensory pits along its anterior margin. Paradiscal fields relatively wide. Paranotal lobes large and long, with trough-curved lower margin reaching metopoclypeal suture.

pronotum (dorsal view); 22 – head and pronotum (lateral view); 23 – fore wing.

Mesonotum 2–2.5 times as long as pronotum, with median and lateral carinae. Fore wings wide, enlarged apically ( Fig. 23 ), with wide hypocostal plate. Clavus as long as whole wing, open. Basal cell large. R 4 (furcating near to basal cell) M 5 (firstly and secondary furcating before wing middle; other branches furcating apically)

CuA 2 (furcating at wing middle). Many transverse veins. Pcu and A 1 fused at middle of clavus. Hind wings rudimentary. Hind tibia with 2 lateral spines in its apical third and with 8 spines apically. First metatarsomere slightly longer than second one, with 2 latero-apical and around 12 intermediate spines arranged in a row without interruption (intermediate spines large near to lateral ones and small in the middle of row). Ventral surface of first metatarsomere with hair-shaped setae.

Second metatarsomere with only 2 latero-apical spines.

COLORATION. General coloration ochre yellow greenish ( Figs 35, 36 ). Pedicel yellow brownish. Fore wings with white costal margin and brownish inner margin of clavus. Thorax, abdominal sternites, and legs sometimes brown. Spine apices black. Gonoplacs with black margins.

MALE GENITALIA ( Figs 16–19 ). Pygofer with slightly convex hind margin

( Fig. 16 ). Anal tube wide, rounded apically (in dorsal view), with lateral margins turned down in shape of triangularly rounded processes ( Fig. 17 ).

Anal column (paraproct) long, almost half as long as anal tube ( Fig. 17 ). Connective with large and wide cup. Phallobase strongly curved – horse-shoe shaped

(in lateral view), wide in proximal half ( Fig. 16 ). Each dorso-lateral lobe with large triangularly rounded process ( Fig. 16, 19 , trp) on its ventral margin (which is weakly sclerotized ( Fig. 16, 19 , vm )) above ventral hooks (in lateral view). Dorsolateral lobes rounded apically, each with oblique transverse carina. Aedeagus with pair of long (more than half as long as phallobase) narrow ventral hooks directed basally, pointed apically. Apical aedeagal processes bilobed apically ( Figs 16, 19 ,

aep). Style with convex hind margin and long and narrow capitulum without teeth

( Fig. 18 ).

FEMALE GENITALIA ( Figs 10–15 ). Sternum VII with deeply concave hind margin bearing small triangular process on weakly sclerotised area ( Fig. 15 ). Anal tube wide, nearly oval, truncate apically (in dorsal view) ( Fig. 11 ). Anal column

(paraproct) long, more than half as long as anal tube. Gonoplacs massive, hemisphaerical, without denticles or teeth ( Figs 10 , 48 ), completely covering posterior connective laminae of gonapophyses IX and anterior connective laminae of gonapophyses VIII. Gonocoxa VIII with convex hind margin. Anterior connective lamina of gonapophyse VIII wide, with a single tooth in apical group and 4 dentate keels in lateral group ( Fig. 13 ). Endogonocoxal process with simple apex. Gonospiculum bridge massive, wide (in ventral view). Posterior connective laminae of gonapophyses

IX with distal parts converging apically under acute angle ( Fig. 14 ). Median field of the laminae in shape of single narrowing apically lobe. Lateral fields of the laminae flat. Bursa copulatrix with a single pouch ( Fig. 12 ).

TOTAL LENGTH. Males – 3.5 mm. Females – 4.0 mm.

DISTRIBUTION. Australia (New South Wales).
