Differential diagnosis. Calomera marmorata is immediately distinguished from all species of the Calomera decemguttata species-complex by its elytra uniquely marked with two conspicuous, elongate blackish marks on the basal area of each elytron and large, blackened discal area ( Figs 224–225 View FIGURES 224–226 , 229–230 View FIGURES 227–235 ) and aedeagus ( Figs 233–235 View FIGURES 227–235 ) with pointed apex in its lateral view ( Figs 233, 235 View FIGURES 227–235 ). Whitish elytral maculation and setal vesture may resemble that in C. durvillei .

Distribution. Endemic to the Salomon Islands. Bougainville is the largest island in the Solomon Islands archipelago; the Autonomous Region of Bougainville is currently part of Papua New Guinea. Specimens (IRSNB) from Buin come from an area near the capital of the South Bougainville District. The natural vegetation of the Solomon Archipelago consists of lowland and tropical forests. Cassola (1987b) examined 59 specimens from the Salomon Islands, all from Bougainville.
