Biology
Lophocateres pusillus lives in storage facilities (warehouses, stores, barns, larders) and feeds on grains. The biology of wild populations is unknown.
Distribution
Lophocateres pusillus is cosmopolitan, although the centre of its distribution, is in south-eastern Asia. The species Lophocateres gounellei is probably a misidentification or a synonym of Lophocateres pusillus. Some new species are known to me from Malaysia.
