Abstract

Atlantochodaeus, a new genus of Ochodaeidae from the Brazilian Atlantic Forest is described, discussed, and illustrated. Additionally, four new species belonging to Atlantochodaeus are described: Atlantochodaeus everardoi n. sp. and Atlantochodaeus paulseni n. sp., both recorded from Rio de Janeiro State; Atlantochodaeus hucheti n. sp. from Espírito Santo, Minas Gerais, Rio de Janeiro, and São Paulo States, and Atlantochodaeus oliviae n. sp. from Minas Gerais State. Detailed descriptions of these species are accompanied by a differential diagnosis and a distribution map. A dichotomous key for all South American genera of Ochodaeidae and the species of Atlantochodaeus is provided to aid in identification. A comprehensive comparative morphology study regarding Parochodaeus pectoralis (LeConte, 1868) (type species of Parochodaeus) and the Atlantochodaeus species are discussed and illustrated. A discussion about gland, mycangium and stridulatory apparatus of Ochodaeinae are also provided. These findings emphasize the richness of the Atlantic Forest and underscore the importance of detailed taxonomic studies in revealing its biodiversity.

巴西大西洋森林金翅甲科金翅甲一新属（鞘翅目，金翅甲总科）。

描述、讨论和说明了来自巴西大西洋森林的一种新属——Atlantochodaeus。此外，还报道了4个属于Atlantochodaeus的新种：Atlantochodaeus everardoi n. sp.和Atlantochodaeus paulseni n. sp.，均记录于巴西里约热内卢州；来自Espírito Santo， Minas Gerais，里约热内卢de Janeiro和s o Paulo州的Atlantochodaeus hucheti n. sp，以及来自Minas Gerais州的Atlantochodaeus oliviae n. sp。这些物种的详细描述附有鉴别诊断和分布图。为帮助鉴定，本文提供了一份对所有南美蛇齿科属和寰齿科种的二分分类表。本文对胸廓鸟（Parochodaeus pectoralis, LeConte, 1868）和大西洋鸟（Atlantochodaeus）进行了全面的形态学比较研究。文中还讨论了蛇齿科的腺体、菌丝和鸣声器。这些发现强调了大西洋森林的丰富性，并强调了详细的分类研究在揭示其生物多样性方面的重要性。
