description: Genus Beraba Martins, 1997
Beraba Martins, 1997: 67.
Beraba – Martins 1999: 178. — Galileo & Martins 2000: 159. — Monné 2005: 137; 2012: 17.
Type species
Beraba moema Martins, 1997 (original designation).
Remarks
The genus Beraba was described by Martins (1997) to accomodate species previously assigned to Eburia. The genus was differentiated from Eburia by the apices of the meso- and metafemora with only an inner spine; integument shiny, antennomere III longer than IV, and the small size, generally smaller than Eburia species. Currently, the genus comprises 17 species.
The key to species of Beraba proposed by Martins (1999) is modified to include four species described subsequently after the publication of the key (B. inermis Martins & Galileo, 2002; B. odettae Martins & Galileo, 2008; B. pallida Galileo & Martins, 2008 and B. tate Galileo & Martins, 2010) and the new species, Beraba hovorei sp. nov.
