Diagnosis. The only known Pyrophanes species with hind femora not swollen and hind tibiae not curved; very similar in dorsal colouration to Pyro. appendiculata colouration differing in having only the lateral elytral margins pale ( appendiculata has both lateral and sutural margins pale, often widely so).

Remarks. Olivier (1883) described L. semilimbata from a female with elytral punctation in lines. Immediately below he described a male, from 'Java ouest' as L. venusta , with the last 3 abdominal ventrites white, and V7 trilobed. Olivier subsequently (1902) synonymised the two species. Both sexes conformed in the narrowly pale colour of the sutural ridge and lateral elytral margins. Olivier did not describe the elytral punctures in lines in the male. Gorham (1903) was unsure of the identification of specimens he described as venusta . Olivier (1913b) probably incorrectly recorded semilimbata (but not the sex of his specimens) from New Guinea, at Erima and Stephansort. Thancharoen et al. (2007 Fig. 5 View FIGURES 3–5 ) distinguished 11 species, including semilimbata , where the original description indicated elytral punctures in lines.

Neither male nor female in MNHN has elytral punctation in lines. Males are very similar in dorsal colouration to Pyrophanes appendiculata and it is possible that Olivier misidentified some of his New Guinean material.

Trisinuata gen. nov.

[ Figs 228–265 View FIGURES 228–238 View FIGURES 239–250 View FIGURES 251–258 View FIGURES 259–265 ]

Type species: Trisinuata caudabifurca View in CoL sp. nov.

Diagnosis. Trisinuata gen. nov. is a New Guinean genus that belongs in a group of 7 genera characterized by: an elongate slender aedeagus with LL concealed behind the ML when viewed from beneath, pronotal width less than width across the elytral humeri, parallel-sided elytra, aedeagal sheath elongate slender, widest across the middle, with posterior half of sternite tapering evenly towards a narrow entire apex; bulbous paraprocts absent. Males have bipartite LOs in V7, expanded horizontal PLP, trisinuate posterior margin of V7, and several species have deflexed elytral apices. Males are distinguished from Colophotia in lacking a median carina on V7, and oblique PLP; from Pteroptyx in lacking bulbous paraprocts and an MFC; from Pyrophanes and Poluninius gen. nov. in lacking incurving lobes along the posterior margin of V7; from Australoluciola gen. nov. which has entire LOs in V7 by the bipartite LOs; from Medeopteryx gen. nov. in having bipartite LOs in V7 with expanded PLP. It differs from Luciola indica in lacking the bulbous median lobe and paraprocts on the aedeagal sheath. Three species are dorsally brown; the remaining species have orange yellow pronota with dark brown elytra. Females associated by label data are macropterous. Larvae are not associated.

Etymology. Trisinuata (feminine) is a noun latinised from the English trisinuate, describing the shape of the posterior margin of V7 where the expanded and lengthened PLP enhance the appearance of the trilobed posterior margin.
