A new subgenus Leasphaericus (of Sphaericus) with two new species, S. (L.) flavipennis and S. (L.) diversevillosus, are described from North West Cape and Barrow Island, in Western Australia. With the exception of one anthropophilous and paracosmopolitan species, the genus Sphaericus had been recorded only from the southern Palaearctic area. The discovery of Australian autochthonous Sphaericus suggests that this genus may be more diversified in other areas, namely in Africa.
