Material examined. Holotype ♂, North-east Queensland, 5 mls ( 8 km) N Bloomfield River, 7–9.v.1970, S.R. Curtis( ANIC[WTH-0326; PT 1016; TRI-39435]).
Diagnosis.With parameres at the base of the phallic apparatus, this species groups with Arc. crescentina, Arc. hugginsi, and Arc. calderabut the parameres are more strongly developed, forming long acute spines, and the apicolateral angles of abdominal sternite IX are produced as simple, elongate, distally convergent processes, whereas in these three other species they can be seen in lateral view to be elaborately bilobed and, at least in part, sinuous.
Description.Male. Length of each forewing, 9 mm(n = 1). Head with anterolateral warts divided clearly; maxillary palps each with segment 5 longer than length of 1-2-3-4 together. In abdomen, membranous sacs somewhat compressed, elongate oval, with total length about as long as 1.5 segments; lateral filaments on segment V short. Genitalia ( Figs 123–125, 170): Tergite IX in dorsal view divided, comprising 2 large areas of short setae, membranous medially, fused with tergite X; sternite IX sclerotised, apical angles extended, forming acute, convergent process on each side, overlapping medially; gonopods in ventral view each with coxopodite length approximately 3xwidth, harpago somewhat flattened, twisted, apex bluntly pointed mesally; phallic apparatus broad at base, tapered and downturned apically, flexible, basally membranous and apically chitinised paramere arising on each side of base. Female. Unknown.
Distribution.Known only from the typelocality in the Wet Tropics of NE Queensland, between CapeTribulation and Cooktown.
