Abstract

Bucerocaputis Souza-Gonçalves & Lopes-Andrade, gen. nov., a new genus with two species, Bucerocaputis kapinawa Souza-Gonçalves & Lopes-Andrade, gen. et sp. nov. from the Caatinga biome and Bucerocaputis timbira Souza-Gonçalves & Lopes-Andrade, gen. et sp. nov. from the Cerrado biome, is described based on individuals collected in the states of Bahia, Maranhão, Pernambuco and Rio Grande do Norte, Northeast Region of Brazil. The genus shares some morphological affinities with members of Acanthocis Miyatake, 1954, Falsocis Pic, 1916, Plesiocis Casey, 1898, Porculus Lawrence, 1987 and Pseudeuxestocis Lawrence 2016; however, it can be distinguished mainly by the combination of the following features: the robust body; single pronotal and elytral punctation; antennae with 10 antennomeres; apical maxillary palpomere inflated with a large circular sensory area at the apex; prosternum biconcave with a relatively broad, strongly curved prosternal process, projecting below the plane of the prosternum disc; and male anterocephalic and anterior pronotal edge quadridentate. We also provide information on its host fungi and briefly discuss its geographical distribution.

巴西塞拉多和卡廷加的蠓属（鞘翅目：蠓科），附二新种记述

根据巴西东北部巴伊亚州、马拉南州、伯南布哥州和大北里约热内卢州收集的个体，描述了一个新属Bucerocaputis souza - gonalves &； Lopes-Andrade, gen. nov.和来自Caatinga生物群的Bucerocaputis kapinawa souza - gonalves &； Lopes-Andrade, gen. et sp. nov.和来自Cerrado生物群的Bucerocaputis timbira souza - gonalves &； Lopes-Andrade, gen. et sp. nov.。该属与Acanthocis Miyatake（1954）、Falsocis Pic（1916）、plesocis Casey（1898）、Porculus Lawrence（1987）和pseudouxestocis Lawrence（2016）的成员在形态上有一定的相似性；然而，它主要可以通过以下特征的组合来区分：坚固的身体；单个前额和鞘翅标点；天线，有10个天线；顶部上颌掌膨大具一大圆形感觉区在先端；双凹的前胸骨具一相对宽，强烈弯曲的前胸骨突，突出于前胸骨盘平面以下；而雄性前脑和前额角为四齿动物。我们还提供了有关其宿主真菌的信息，并简要讨论了其地理分布。

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.
