Trisinuata dimidiata sp. nov.

[ Figs 242–250 ]

Holotype. Male. NEW GUINEA: Western Highlands Pr. , Chimbu District , Kondiu, Catherine Mission, October 25, 1969, J.E. Lloyd, (G414) ( ANIC).

Paratype (1). NEW GUINEA: Western Highlands Pr. , Chimbu District, Kondiu recorded male November 9 1969, J.E.Lloyd (G541) ( ANIC) .

Code name. Luciola 13 ( Lloyd 1973a)

Male. 7.5–7.8 mm long. Colour ( Fig. 242 ): pronotum shiny yellow, semitransparent; MN pale brown with median brown area; MS and elytra uniformly dark brown; ventral surface of pronotum yellow; remainder of ventral surface of body, including posterior margin of V7, dark brown, except for narrow white posterior margin of V5, white LO in V6, and white LO halves in V7 ( Fig. 243 ); basal abdominal tergites dark brown; T6, 7 and 8 pale cream with brown mottling in holotype, T8 white and T7 white with brown markings along posterior half in paratype ( Fig. 247 ). Pronotum ( Fig. 242 ): 1.2–1.3 mm long; 1.6–1.8 mm wide; W/L 1.3–1.4; punctures small, shallow, contiguous or separated by up to their width; midanterior margin rounded, projecting considerably beyond rounded obtuse anterolateral corners; lateral margins diverging in anterior half, and converging posteriorly in posterior half with slight sinuousity on right side in holotype; posterolateral corners narrowly rounded. Elytra shiny, punctures dense, some contiguous. Abdomen ( Figs 243–250 ): posterolateral corners of V6 narrowed, appearing prolonged if viewed from above in ethanol preserved G541 ( Figs 243, 244, 247 ). LO ( Figs 243, 245 ) not extending into PLP which are slightly truncate along their inner posterior margins; lateral margins of V7 strongly divergent in ethanol preserved G541; MPP moderately broad, apex truncate or very slightly emarginated ( Figs 248, 249 ). T8: flanges narrowly elongate, apex rounded ( Fig. 250 ).

Female, larva unknown.

Etymology. dimidiata (dimidius, Latin = half) emphasizes the pattern of light production of the single paratype male. Lloyd’s field records for the holotype (G414) are “single at ½ sec”.
