Diagnosis. Triangulara belongs to that group of S. E. Asian Luciolinae having pale yellowish dorsal surface (including a pale pronotum), with black tipped elytral apices. In the male the aedeagal LL are visible beside the ML when viewed from beneath in common with 17 other genera. Males are most obviously distinguished by the triangular outline of the LO in V7 and the separation of the LO from the sides and posterior margin of V7; it is most similar to Sclerotia Ballantyne from which it is distinguished by the triangular outline of the LO in V7, no anteromedian emargination of the V7 LO, and no sclerites surrounding the aedeagal sheath. (In Sclerotia the LO may occupy all of V7, or may appear heart shaped, with an anterior median emargination often so deep that the LO appears U shaped; a set of 3 sclerites surround the posterior area of the aedeagal sheath). It is distinguished from the similarly coloured Abscondita Ballantyne most obviously by the triangular shape of both the LO and V7, the separation of the aedeagal LL along most of their dorsal length and the absence of bulbous projections from the lateral margins of the LL. (In Abscondita the LO in V7 occupies most if not all the area of V7 which is broadly rounded behind and often very flat; the LL are fused along almost all of their dorsal length, and bulbous projections arise from the lateral margins of the LL). Confused in collections with Scl. aquatilis and Scl. substriata . Female macropterous and coloured as for male except for pale terminal Vs 6 and 7. Larva unknown but preliminary observations by Pimpasalee indicate it may be aquatic.
