Abstract

The leaf chafer tribe Alvarengiini Frey, a long-neglected taxon that has been overlooked in the biodiversity literature from its inception, is revised for the first time. As a result of this research, the tribe is composed of two species in two genera distributed from Bahia, Brazil (in the north), to Paraná, Brazil (in the south), and Paraguay. Two synonyms are proposed: Alvarengius silphoides Frey, syn. nov. for Ottokelleria dispar (Burmeister) and Alvarengius Frey, syn. nov. for Ottokelleria D'Andretta & Martínez. A new genus is described, Carinochilus, gen. nov., and includes one species: Carinochilus marginatus (Burmeister), comb. nov. The lectotype for O. dispar and a neotype for C. marginatus are designated. We provide an identification key to the tribes of Rutelinae (in English and Portuguese) and incorporate classification changes in the subfamily. A key for the identification of Alvarengiini genera and species is also provided. All taxa are circumscribed and illustrated, and distributional data are synthesised in maps.

Revision of the Neotropical tribe Alvarengiini Frey, 1975 (Coleoptera: Scarabaeidae) 新热带Alvarengiini族的修订（鞘翅目：猩红蛾科

叶茶藨子科（Alvarengiini Frey）是一个长期被忽视的类群，从一开始就被生物多样性文献所忽视，本研究首次对其进行了修订。研究结果表明，该族由两个属中的两个种组成，分布于巴西巴伊亚（北部）、巴西巴拉那（南部）和巴拉圭。提出了两个异名：Alvarengius silphoides Frey，syn. nov. for Ottokelleria dispar (Burmeister) 和 Alvarengius Frey，syn. nov. for Ottokelleria D'Andretta & Martínez。描述了一个新属，Carinochilus，gen. nov.，包括一个种：Carinochilus marginatus (Burmeister), comb.我们指定了 O. dispar 的标准模式和 C. marginatus 的新模式。我们提供了 Rutelinae 各族的鉴定检索表（英语和葡萄牙语），并纳入了该亚科的分类变化。我们还提供了 Alvarengiini 属和种的鉴定检索表。所有分类群均有圈定和插图，分布数据在地图中进行了综合。

期刊介绍： Austral Entomology is a scientific journal of entomology for the Southern Hemisphere. It publishes Original Articles that are peer-reviewed research papers from the study of the behaviour, biology, biosystematics, conservation biology, ecology, evolution, forensic and medical entomology, molecular biology, public health, urban entomology, physiology and the use and control of insects, arachnids and myriapods. The journal also publishes Reviews on research and theory or commentaries on current areas of research, innovation or rapid development likely to be of broad interest – these may be submitted or invited. Book Reviews will also be considered provided the works are of global significance. Manuscripts from authors in the Northern Hemisphere are encouraged provided that the research has relevance to or broad readership within the Southern Hemisphere. All submissions are peer-reviewed by at least two referees expert in the field of the submitted paper. Special issues are encouraged; please contact the Chief Editor for further information.
