El genero Diastolinus (Coleoptera: Tenebrionidae: Pedinini) en las Islas Caiman con descripcion de una nueva especie.

Orlando H. Garrido, Esteban Gutierrez

Abstract


A new species of Diastolinus D burtoni is described for the Islands of Grand Cayman and Cayman Brac (Cayman Islands). Local forms are characterized by displaying a conspicuous enlargement of the front tibia, character not found in any Cuban species. However, Diastolinus dentipes (endemic to Grand Cayman) was also collected in Cayo Largo del Sur, Archipelago de Los Canarreos, Cuba. Therefore this species, could no longer be considered endemic to the Cayman Islands. Whether the original dispersion occurred from Cayman Island to Cayo Largo or vice versa, is hard to prove, nevertheless, the distinctive character of the dilatation of the front tibias of Caymanian's animals strongly suggest the former variant.
