Arcyphysa lovedayi sp. nov. (Figs 130–131, 164–165) Material examined. Holotype ♂, Queensland, Killarney District, 3.iv.1955, Loveday (NMV). Other material examined. 1♂, Papua New Guinea, Port Moresby, Feb 1963, coll. A. Flynn, reared K. Koorboot [TRI-54708]. Diagnosis. This species superficially resembles Arc. flinti in having a simple curved process lateromesally on the distal margin of segment IX. However, it is more closely similar to Arc. naumanni, in that both species have in lateral view a ventrally directed spine apicomedially on the lateral margin of abdominal segment IX. Arcyphysa lovedayi is distinguished from Arc. naumanni by the rounded apices on the apicolateral processes and by the absence of a dorsal ‘horn’ subapically on each harpago. Description. Male. Length of each forewing: 8.2 mm (n = 1). Reticulate-walled internal sacs elongate ovoid, almost length of 2 segments. Genitalia (Figs 130–131, 164–165): Tergites IX and X fused; apicolateral processes of even width throughout length, in ventral view curved outwards and in lateral view curved upward subapically, sternite IX with paired acute spines below phallus on apicolateral margins; gonopods in ventral view each with coxopodite arched widely, slightly tapered distally, harpago about 1/4 length of coxopodite, beak-like apically; phallic apparatus without parameres, broad-based, strongly arched ventrad at about midlength. Distribution. Known from only 2 specimens: The type specimen collected in the Killarney District on the border of SE Queensland and New South Wales, to the west of the Border Ranges and the other from southern Papua New Guinea.
