What is "galerucinae"

The Galerucinae are a large subfamily of the leaf beetles ( Chrysomelidae), containing about 5800 species. It includes the flea beetles in tribe Alticini.

The division into five tribes is more a matter of tradition than based on modern research. Some genera, for example Yingaresca, are better considered incertae sedis due to a general lack of knowledge. And while a good case can be made for some tribes – namely the Alticini and Galerucini – being all but monophyletic even in their traditional delimitation, others – like Luperini or Sermylini – appear to be just paraphyletic assemblages of primitive and more basal genera.
