Chlamydocassis (s. str.) perforata ( Boheman, 1850)

Published record. São Paulo (BඈΗൾආൺඇ 1862).

Distribution. Argentina, Bolivia,? Brazil (Rio Grande do Sul, São Paulo), and Peru.

Remarks. Presence of C. perforata should be verified by more material and examination of the published specimens. In general, species of Chlamydocassis Spaeth, 1952 in HංඇർΚඌ (1952) are morphologically very variable and some populations are hard to identify correctly. Moreover, many species have quite a wide range through southern parts of tropical and subtropical South America, and local populations are distinct. The genus needs a complex revision, which should combine morphology with molecular methods to delimit the borders among species. Chlamydocassis perforata is the most common species of the genus in Bolivian savannas (Chiquitania, which is also its terra typica) and very likely reaches to the Brazilian state of Mato Grosso do Sul but based on the present material the species would not have a particularly wide range: Vංൺඇൺ (1964b) did not recognize the species in the material he studied despite having a very large sample of Argentinean Chlamydocassis , and the presence of C. perforata in Argentina is based on a single specimen from the province of Chaco (Bඈඋඈඐංൾർ 1996).
