Polyphagous. Recorded on six hosts from three families including Myrtaceae. Edible hosts include guava and edible Syzygium (water apple, Malay apple).
Bismarck Archipelago of Papua New Guinea; Bougainville Island.
B. obliqua is similar to B. psidii (Froggatt) in possessing a broad black triangular marking on dorsal surface of scutellum, infuscation on crossveins and mesonotum black with medial postsutural vitta absent but differs in having a black face, r-m crossvein longer than dm-cu crossvein, lateral postsutural vittae very short and narrow ending just behind sa. setae, legs with all tibiae and apices of femora and apical 4 segments of tarsi fuscous.
