Caxambu and Almeida 1999 : 244; Caxambu and Almeida 2003 : 330. Type species. Lamprosoma bicolor Kirby, 1818: 445. By monotypy. Figure 34. Lamprosoma azureum Germar (3)., left: habitus (dorsal view), right: habitus (lateral view). Diagnosis. body length about 4.5 mm; tarsal claws appendiculate with broad tooth; antenna short, antennomere VIII nearly as wide as VII or IX. Metallic coloration (some species multicolored), head not visible from above, clypeus excavate. According to Monros (1956b) it can be differentiated from other Neotropical genera by having appendiculate claws at 180 ° angle, while Dorisina and Lychnophaes have simple claws at a more obtuse angle. Distribution . Nearctic, Neotropical, in Argentina limited to north, and northeastern provinces. Remarks. Adults feed on plants of the families Bombacaceae , Combretaceae , Melastomataceae , Mimosaceae . Therefore, some species have been considered as potential biological control agents for these plants ( Caxambu and Almeida 2003 ). Argentinian species checklist. 1.
