Anasta prognatha (Distant, 1906) View in CoL
( Figs 1 View FIGURE 1 C, 3C, 10–12)
Dictyophara prognatha Distant, 1906: 352 ; Melichar, 1912: 125; Metcalf, 1946: 174. Anasta prognatha (Distant) : Emeljanov, 2008: 371.
Redescription. Body length (from apex of cephalic process to tip of forewings): ♂ 10.8–11.9 mm; length of head: 2.0– 2.1 mm; width of head (including eyes): 1.2–1.3 mm; length of forewings: 8.7–9.3 mm.
Cephalic process ( Fig. 10A View FIGURE 10. A –C) in front of eyes moderately elongate and upturned. Vertex ( Fig. 10A View FIGURE 10. A ) with the ratio of length in central line to width in base (2.27–2.66):1; median carina distinct and sharp between eyes. Frons ( Fig. 10 View FIGURE 10. A B) elongate, lateral and intermediate carinae ridged, median carina distinct, more or less weak apically and maybe invisible at apex. Forewings ( Fig. 3 View FIGURE 3 C) with stigmal area obscure viridescent, with 1–2 transverse veins.
Male genitalia with gonostyles ( Fig. 11 View FIGURE 11. A D) large and broad, apex slightly convex; upper process elongate, slightly curved inwards, acute apically. Aedeagus ( Fig. 12A View FIGURE 12. A –C) very similar to A. australiaca , but ventrolateral lobes larger and longer, dorsal end directed dorsally, 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. 11A View FIGURE 11. A ) relatively broad and large, lateral margin somewhat diverging towards apex, with the ratio of length to width in base about 1.4: 1 in dorsal view; ventral apical margin conspicuously concave.
Material examined. AUSTRALIA: 2♂, North Queensland, Tozer Range, North Foot 400’, 1–5.VII.1948, L.J. Brass (Archbold Exped., AMNH). PAPUA NEW GUINEA: 1♂, SE Weam, 9 m, light trap, 18.VI.1964, H. Clissold; 2♂, SE Moorhead [Morehead], 18 m, light trap, 4.VII.1965, H. Clissold (BPBM).
Remarks. The specimens from Papua New Guinea are distinctly smaller than those from North Queensland, Australia. The length of head is also shorter than that of Australia. They are maybe representing a subspecies of A. prognatha , but more specimens from Papua New Guinea need to be examined for confirmation.
Distribution. Australia (North Queensland), Papua New Guinea.
