( Figs 1View FIGURE 1 A, 3 A, 4–6)

Fulgora australiaca Lallemand, 1935: 674  , Figs 16, 17.

Dictyophara australiaca (Lallemand)  : Metcalf, 1946: 149.

Redescription. Body length (from apex of cephalic process to tip of forewings): ♂ 9.9–10.5 mm; length of head: 1.4–1.6 mm; width of head (including eyes): 1.1–1.2 mm; length of forewings: 7.8–8.1 mm.

Cephalic process ( Fig. 4 AView FIGURE 4. A –C) in front of eyes distinctly short and upturned. Vertex ( Fig. 4 AView FIGURE 4. A) with the ratio of length in central line to width in base (1.65–1.72): 1; median carina distinct and sharp between eyes. Frons ( Fig. 4View FIGURE 4. A B) elongate, lateral and intermediate carinae ridged, median carina distinct, more or less weak apically and or lacking apically. Forewings ( Fig. 3View FIGURE 3 A) with stigmal area obscure viridescent, with 0–2 transverse veins.

Male genitalia with gonostyles ( Fig. 5View FIGURE 5. A D) large and broad, apex with a small obtuse process; upper process elongate, slightly curved inwards, acute apically. Aedeagus ( Fig. 6 AView FIGURE 6. A –C) large and robust, dorsal part and bases of ventral and lateral parts on phallobase sclerotized and pigmented, the remainder membranous; dorsal part elongate, V-shaped apically, with a pair of small sclerotized apical processes, directed posteriorly in dorsal view, the base of processes membranous sac-like and inflated inwards; ventrolateral parts produced in a pair of large, sac-like and inflated lobes, transversely prolonged: rounded in middle and tapered at each end, dorsal end more or less sclerotized, directed posteriorly, ventral end elongated, incurved ventrally and crossed each other in ventral view; ventral part with a small lobe in middle under the ventrolateral lobes. Segment X ( Fig. 5 AView FIGURE 5. A) relatively broad and large, lateral margin somewhat diverging towards apex, with the ratio of length to width in base about 1.3: 1 in dorsal view; ventral apical margin truncated and straight.

Material examined. AUSTRALIA: 2 ♂, North Queensland, Lockirbie, 14–17.VII. 1948, L.J. Brass (Archbold Exped., AMNH).

Remarks. This species is externally similar to A. vitiensis Emeljanov & Wilson  , but can be distinguished from the latter by the shorter cephalic process and the bigger ventrolateral lobes in aedeagus. See also the key for identification.

Distribution. Australia (North Queensland).
