description
Description (modified after Mosely, in Mosely & Kimmins 1 953). Male. Small, length of each forewing: 6 – 7 mm (n = 2). In abdomen, glandular sacs large, distal pair rounded, proximal pair elongate. Genitalia (Figs 112, 156 – 157): Tergite X in dorsal view subquadrate, cleft midapically; abdominal segment IX with apicolateral processes swollen, globose distally, narrowed abruptly to sharply pointed apices; gonopods with coxopodites stout and slightly sinuous in basal twothirds, harpagones elongate, length about 6 times width; phallic apparatus stoutest in middle region, narrowed towards apex, in lateral view strongly curved downwards, without spines or parameres. Female. Unknown.
diagnosis
Diagnosis. This species shares with other species in the genus Arcyphysa the presence of elongate apicolateral processes on abdominal segment IX, their distally globular and apically sharply pointed shape most closely resembling processes seen in lateral view in Arcyphysa hugginsi. Unlike Arc. hugginsi, this species lacks parameres on the phallus and the gonopods in ventral view are stout and slightly sinuous basally, the harpagones are narrowly digitate, acute apically. The form of tergite X in dorsal view is truncate and cleft medially at the apex, more closely resembling Arc. sybillae. Only two specimens are available at present, the type from ‘ Queensland’ and a specimen from Crystal Cascades near Cairns in north-eastern Queensland.
distribution
Distribution. Known only from Queensland, including the unspecified type locality ' Queensland' that is probably in far north-eastern Queensland as for the more recently collected specimen.
