Abstract

Gibboryctes Endrödi, 1974 (Coleoptera: Scarabaeidae: Dynastinae: Oryctini) is an uncommon Neotropical genus comprising five valid species (Gasca-Álvarez Ratcliffe 2011; Dupuis 2019). Endrödi (1974) established the genus based on Gibboryctes szelenyii Endrödi, 1974 and defined it by the absence of sexual dimorphism; short, triangular, and pointed clypeus; bidentate mandibles projected beyond the anterior clypeal margin; and protibiae quadridentate. After that, Gibboryctes waldenfelsi (Endrödi, 1977) and Gibboryctes gracilicornis (Prell, 1912) were assigned to Gibboryctes, from Strategus Kirby, 1828 and Heterogomphus Burmeister, 1847, respectively (Ratcliffe Dechambre 1983; Dupuis Dechambre 2008). Gibboryctes bollei Dechambre, 2006 and Gibboryctes impunctatus Dupuis, 2019 were subsequently described.

摘要

Gibboryctes Endrödi, 1974（鞘翅目：金龟科：臂金龟亚科：象鼻虫族）是一个不常见的新热带属，由五个有效物种组成（Gasca-Álvarez Ratcliffe 2011；Dupuis 2019）。Endrödi（1974）基于 Gibboryctes szelenyii Endrödi, 1974 建立了该属，并通过缺乏性二态性、短而三角形、尖锐的额、二齿的下颚突出于额缘前缘以及前胫骨四齿来定义它。此后，Gibboryctes waldenfelsi（Endrödi，1977）和 Gibboryctes gracilicornis（Prell，1912）分别从 Strategus Kirby，1828 和 Heterogomphus Burmeister，1847 被归入 Gibboryctes（Ratcliffe Dechambre 1983；Dupuis Dechambre 2008）。随后描述了 Gibboryctes bollei Dechambre，2006 和 Gibboryctes impunctatus Dupuis，2019。
