Abstract

Four species of Chilean leaf beetles in the subfamily Chrysomelinae have been cytogenetically analyzed, Blaptea elguetai Petitpierre, 2011, Henicotherus porteri Bréthes, 1929 and Jolivetia obscura (Philippi, 1864) show 2n = 28 chromosomes and a 13 + Xyp male meioformula, and Pataya nitida (Philippi, 1864) has the highest number of 2n = 38 chromosomes. The karyotype of Henicotherus porteri is made of mostly small meta/submetacentric chromosomes, and that of Jolivetia 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.

摘要

对叶甲亚科的四种智利叶甲进行了细胞遗传学分析，2011年的埃尔盖塔叶甲（Blaptea elguetai Petitpierre）、1929年的波特氏异叶甲（Henicotherus porteri Bréthes）和1864年的暗色乔利叶甲（Jolivetia obscura (Philippi, 1864)）显示有2n = 28条染色体和13 + Xyp雄性减数分裂公式，而1864年的闪亮帕塔叶甲（Pataya nitida (Philippi, 1864)）拥有最多的2n = 38条染色体。波特氏异叶甲的核型主要由小的中着丝粒/亚中着丝粒染色体组成，而暗色乔利叶甲在粗线期常染色体二价体上使用常规染色显示出明显的着丝粒异染色质块。结合该亚科先前的细胞遗传学数据和当前分类学对这些发现进行了讨论。
