All paratypes are labelled as “ PARATYPE ♂ - ♀ / Acizzia aliceae / Percy & Martoni 2025 ” (Printed on blue card). Diagnosis. Although a number of undescribed species of Acizzia associated with Dodonaea have been reported recently, and are in the process of being described (McClelland et al. 2025), the only currently described species of Acizzia associated with Dodonaea is Acizzia dodonaeae (Tuthill, 1952). Geographically, distributions of A. aliceae and A. dodonaeae do not overlap, and the two species are easily distinguished morphologically due to the absence of any wing pattern in A. aliceae. Furthermore, the male parameres of A. aliceae are broader and less sinuous than those of A. dodonaeae, while the female proctiger is less arched posteriorly (Tuthill 1952). Description. Colouration. Adult. Body generally pale to dark green (dried or ethanol-preserved material yellow); dorsum of thorax varying from a dark green to a dark brown (Fig. 12 A – D), pronotum, mesopraescutum and mesoscutum all with longitudinal parallel darker bands. Abdomen lighter coloured. Antennal segments 1 and 2 lighter, segments 3–7 darkening apically, segments 8–10 uniformly dark (Fig. 12 B – D). Wings hyaline, often yellowish, with darker veins and radular areas (Fig. 12 E, F). Male terminalia pale, with paramere tips darker (Fig. 12 A, C). Female terminalia pale, with tip of proctiger darker (Fig. 12 B, D). Immature (5 th instar): Body pale green to yellow-green (Fig. 12 G). First four segments of antenna uniformly yellow-green, segments 5, 6, and 7 tending to a darker colour in the apical portion, last three segments of antennae uniformly dark brown-black. Structure. Adult. Body relatively large, 2–3 mm from anterior margin of vertex to tip of folded wings (males smaller than females) (Fig. 12 A – D). Head (Fig. 13 C – G) in lateral view slightly deflexed downward, wider than thorax, width <0.5 × antennal length, vertex width almost 2 × length, with well-defined cranial suture. Genal processes well developed, conical, diverging and distinctly downturned at apices, length ~ 3 / 4 vertex length, apices rounded, curiously naked patches on the dorsal surface at base lacking setae or microsculpture, similarly naked areas surround the discal foveae on vertex (Fig. 13 D). Clypeus subglobular, terminal proboscis segment short (Fig. 13 F). Antennae 10 - segmented, with segment 3 longest, length of segments 4–8 subequal, and the shorter terminal segments 9 and 10 subequal; a single subapical rhinarium on segments 4, 6, 8, 9, simple, circular, length of two long terminal setae subequal, with both shorter than segment 10 (Fig. 13 G). Thorax (Fig. 13 H, I) moderately arched in lateral profile. Hind legs (Fig. 13 J – L) with meracanthus well developed, thorn-like and slightly curved; metafemur shorter than metatibia and with a cluster of 4–6 stout setae subapically on outer lateral surface (Fig. 13 L); metatibia with a single genual spine basally and 1 + 4 (typically with two close together) or occasionally 1 + 3 sclerotised apical spurs surrounded by a crown of 8–10 stout setae; length of metatarsal segments subequal; metabasitarsus with a single outer sclerotised spur. Fore wing (Figs 12 E, F, 13 A) length> 2.5 × width, more or less parallel sided, widest in apical half, rounded at apex; pterostigma long and slender; cells m 1 and cu 1 both elongate, but m 1 narrower and more elongate than cu 1, vein Rs long and moderately sinuous, vein M much shorter than Rs and strongly arched; membrane with spinules densely distributed in all cells and with spinule-free bands along veins, marginal radular spinule clusters positioned centrally in cells m 1 and m 2, and in posterior half of cell cu 1 (Fig. 13 B). Male terminalia (Fig. 14 A – D) with subgenital plate somewhat elongate, length greater than height, dorsal margin sinuate and ventral margin not evenly rounded (Fig. 14 A, C). Proctiger shorter than paramere, expanded basally into distinct basal posterior lobes that extend outwards from below and around a weakly sclerotised hook-like appendage, upper portion narrow, cylindrical, but tubular only in apical 1 / 3 (Fig. 14 E). Paramere in lateral profile, sinuous, widest in middle, anterior margin medially arched forward and bearing many long setae, posterior margin moderately concave, bearing fewer long setae, apex blunt and directed rearward, moderately sclerotised and bearing two distinctly stout setae subapically on inner surface, otherwise inner surface with scattered short setae, outer surface with few short setae concentrated towards the posterior margin (Fig. 14 A, C, D). Distal segment of aedeagus moderately long, base expanded laterally, apical portion somewhat saccate below a bluntly acute tip and deeply incised dorsum, apical portion ~ 1 / 3 as long as the distal segment length (Fig. 14 B, D). Female terminalia (Fig. 14 F – J) short, with proctiger arched dorsally and steeply downturned post anus, covered in numerous long setae in the distal half and terminating in an acute, sclerotised tip (Fig. 14 F), in dorsal view broadly rounded apically; anal ring outline in dorsal view pyriform, narrower anteriorly and broader posteriorly, length ~ 1 / 2 proctiger length, composed of a double row of regular pores (Fig. 14 G, I); subgenital plate shorter than proctiger, length ~ 3 / 4 proctiger length, apex blunt except for a small beak and whole covered in medium to short setae (Fig. 14 F, H); ovipositor dorsal valvulae triangular but with a long narrow extension dorsally, ventral valvulae bearing a single small tooth ventrally (Fig. 14 J). Egg elongate with “ puzzle-piece ” striations over most of the surface, and a short, stout, lateral pedicel 1 / 4 length from base, apical filament apparently lacking (Fig. 14 N). Immature (5 th instar): body ~ 1.55 × as long as wide, shape ovoid, wing pads protruding (Fig. 12 G). Setae predominantly a mix of medium to long simple and weakly capitate, with a single long capitate seta at the apex of each wing pad, a few shorter capitate setae on antennae and legs, and abdomen with 4 + 4 long capitate setae (Fig. 12 G). Antenna length ~ 1.3 × head width, 9 - segmented with a single subapical rhinarium on segments 3, 5, 7, and 8, segment 3 longest and approx. equal to length of segments 8 and 9 combined (Fig. 12 G, I). Fore wing pads lacking humeral lobes. Tarsal arolium longer than claws, triangular with unguitractor and long pedicel (Fig. 12 H), claws well developed. Anus in ventral position (Fig. 12 G), circumanal ring shallowly heart-shaped, consisting of a single row of pores (Fig. 12 J). Measurements (in mm). Adults (5 ♂♂, 5 ♀♀).
