( Figs 113–115 , 160, 161 , 187) Material examined. Holotype ♂ , New South Wales , Brown Mountain , 18.i.1961 , E.F. Riek ( NMV [PT-1017]). Diagnosis. Alone among Australian species of Diplectroninae , Arcyphysa candela has a pair of small digitiform lobes dorsolaterally on the apical margin of abdominal segment IX, here suggested to be homologous with the elongate apicolateral processes of other species in the genus. This feature distinguishes Arcyphysa candela from Arc. angusta and Arc. diamontona , with which it shares the characteristic of strongly bowed coxopodites. Description. Male. Length of each forewing: 9.8 mm (n = 1). Lateral filaments short, internal sacs small, ovoid, less than 0.5x length of segment. On head, anterolateral warts distinctly divided. Male. Genitalia ( Figs 113–115 , 160–161 ): Abdominal segment IX laterally partially fused with tergite X, sharp triangular projection middorsally, lateral extensions of apicolateral margins absent, dorsally with pair of digitiform or candle-like processes tipped with seta apicolaterally; gonopods sinuous in ventral view and broadly curved, each with coxopodite rod-like in lateral view, harpago almost 1/4 length of coxopodite, length about 2x width, tapered, directed mesad; phallic apparatus stout basally, narrower in distal half, without chitinised spines, with slender upturned lip apically. Female. Unknown. Distribution. Known only from the type locality in SE New South Wales . Remarks. Unfortunately, the body of the holotype is badly bleached, making it very difficult to be sure of some features.
