A genus of Brachyiulini differing from contribal genera by the following combination of characters: promeres positioned completely anteriorly in relation to opisthomeres; promere very short, on average half as long as opisthomere; opisthomere possessing a clearly discernible basoposterior process, the latter sometimes tightly contiguous with CBO, a usually well-pronounced lateral process (very small in some species), which is strongly mesolaterally flattened, and an anterior process; some species with a mesoanterior process.
