Comments. This unnamed species, similar to B. punctatum , was previously recognized as new about 100 years ago by J. Achard who labelled the specimen as the unpublished name - Heteroscapha papuanum n. sp-. The species may be readily distinguished from B. punctatum by the elytra having basal striae interrupted at level of the humeral areas, the coarse elytral punctures forming two longitudinal impressed rows, and absent from the remaining discal surface, the mesoventrite smooth, lacking a median ridge, the median part of the metaventrite convex, lacking striae, bearing two coarse punctures situated between the mesocoxal cavities and three or four coarse punctures on the lateral part of the metaventrite near its anterior margin. Nevertheless, it seems preferable to keep this species unnamed as long as male characters are unknown.
