Abstract:

Four species of Chilean leaf beetles in the subfamily Chrysomelinae have been cytogenetically analyzed, Blaptea elguetai Petitpierre, 2011, Henicotherus porteri Bréthes, 1929 and Jolivetiaobscura (Philippi, 1864) show 2n = 28 chromosomes and a 13 + Xyp male meioformula, andPataya nitida (Philippi, 1864) has the highest number of 2n = 38 chromosomes. The karyotype ofHenicotherus porteri is made of mostly small meta/submetacentric chromosomes, and that ofJolivetia obscura displays striking procentric blocks of heterochromatin at pachytene autosomic bivalents using conventional staining. These findings are discussed in relation to previous cytogenetic data and current taxonomy of the subfamily.
