Van Deusen, vi–21– 26–1964, male; vi–8–1964, 2 males ( AMNH) .

Diagnosis. One of four species from New Guinea with brown dorsal colouration; distinguished from Aus. fuscamagna sp. nov. and Aus. fuscaparva sp. nov. by the bipartite LO in V7, and Tri. papuae by the absence of a deflexed elytral apex.

Male. 6.7–7.2 mm long. Colour ( Fig. 251 ): entirely dark brown except for white V6, 7 and pale T6–8 ( Figs 253, 254 ). Pronotum: 1.5–1.7 mm wide; 1.0– 1.1 mm long; W/L 1.5–1.7; punctures shallow, separated by width of puncture or contiguous; pronotal disc smooth and shiny between punctures; lateral margins diverge along length (C>A, B). Head: GHW 1.3–1.4 mm; ASD <ASW. Abdomen ( Figs 253, 254, 255 ): muscles attaching in median area between LO halves are visible through cuticle, LO extending to sides of V7 and into PLP; MPP wider than long, curving dorsally at its apex which is bifurcate into 2 fine points, shorter and narrower than wide PLP ( Fig. 254 ). T8 ( Fig. 255 ): well defined, wide lateral ridges and short wide apically rounded flanges. Aedeagus ( Figs 257, 258 ): anterior prolongation of ML not long and slender; apices of LL concealed behind ML and not laterally expanded; lateral margins of LL very slightly curved.

Remarks. Olivier (1913b) based this species on a female. The similarity of pronotal colour to the type female is most obvious in these males. Table 9 lists Luciolinae with dark dorsal colouration.
