Arcyphysa naumanni  sp. nov.

( Figs 128–129View FIGURES 117–131)

Material examined. Holotype ♂, Queensland, 13°44’S 143°20’E, 11 km W by N Bald Hill, McIlwraith Range, 500 m, 26.vi.1989, I.D. Naumann ( NMV [PT-2042]).GoogleMaps 

Paratype 1 ♂, Queensland, Mt Tozer, Iron Range , 300 m, 30.iv.1973, S.R. Monteith ( NMV [TRI-39432]). 

Diagnosis. The ventral view of the male genitalia superficially resembles that of Arc. flinti  , but Arc. naumanni  differs from that species in having in lateral view a ventrally directed spine apicomedially on each lateral margin of abdominal segment IX and a dorsally directed subapical process on the harpago of each gonopod. Arcyphysa lovedayi  also exhibits this feature but differs from Arc. naumanni  in having the apicolateral processes on abdominal segment IX rod-shaped and rounded apically, not lanceolate with acute apices, and in lacking any modification of the harpagones.

Description. Male. Length of each forewing: 5.1 mm (n = 1). In abdomen, reticulate-walled glands ovoid, about one segment long; lateral filaments on segment V almost length of segment. Genitalia ( Figs 128–129View FIGURES 117–131): Tergite IX partially fused with tergite X; down-turned sclerotised spine apicomedially on each lateral margin of sternite IX; single pair of lanceolate apicolateral processes extending posterad well past apex of tergite X and tip of gonopods; gonopods stout, widely separated, each with harpago having 'beak-like' dorsal expansion; phallic apparatus stout, without parameres.

Distribution. Known only from northern Cape York in far north Queensland.
