Abstract

Sucinolivolia torpida gen. nov. et sp. nov. (Coleoptera: Chrysomelidae: Galerucinae: Alticini) is described and illustrated from Eocene Baltic amber. The new monotypic genus is compared with fossil and extant flea-beetle genera. Sucinolivolia gen. nov. is similar to the extant Livolia Jacoby and Orthaltica Crotch, but difference include the absence of an antebasal pronotal sulcus, not crenulate lateral pronotal margins, possessing very short genae, more robust legs, and the shape of tibiae. Including this new record, six described species of Alticini are known from Baltic amber.

摘要

琥珀光叶跳甲属（Sucinolivolia）新属及新种（鞘翅目：叶甲科：叶甲亚科：跳甲族）由始新世波罗的海琥珀描述并绘图。该新单型属与化石及现存的跳甲属进行了比较。琥珀光叶跳甲属与现存的光叶跳甲属（Livolia Jacoby）及直缘跳甲属（Orthaltica Crotch）相似，但区别在于前胸背板无前基部沟，前胸背板侧缘不具细圆齿，颊极短，腿更粗壮，以及胫节形状。包括这一新记录，已知有六个已描述的跳甲族物种来自波罗的海琥珀。
