Introduction
Bacaniini, along with the possibly related Abraeinae, have been informally lumped together as ‘microhisteridae’. All of the genera exhibit very small (most < 2mm) body size. Together the genera listed contain slightly over 100 described species. Bacanius, by far the largest genus, is cosmopolitan. The others are more restricted. The species are poorly known taxonomically and biologically. Many hundreds remain to be described from both New and Old World tropics.
Characteristics
Bacaniini are readily recognized among histerids by the reduction and concealment of the propygidium under the elytra. All known species are strongly convex and ovoid, many nearly spherical.
Discussion of Phylogenetic Relationships
Relationships among the genera of Bacaniini have not been examined. It is highly likely that Bacanius itself is paraphyletic, possibly with respect to all the remaining bacaniine genera.
