Belonuchus is a diverse genus in the subtribe Philonthina (subfamily Staphylininae, tribe Staphylinini), with some of its species being frequently collected. For the majority of the Mexican species of Belonuchus, little or no taxonomic information has been reported after their original description. For this reason, the Mexican species of Belonuchus were taxonomically revised based on the study of specimens deposited in several Mexican and international collections. We propose eight species groups to accommodate the Mexican species, five of them supported by one unique diagnostic character. Keys to species groups and species in each group, together with photos and drawings of diagnostic structures, are included. Redescriptions of the 29 known species, descriptions of 16 new species, with information about intraspecific variation in terms of secondary sexual dimorphism and size, two new country records (Mexico and Guatemala) and 26 new state records are also included. We propose B. xanthopus Solsky, 1868 and B. celatus (Sharp, 1885) as new synonyms of B. connexus (Say, 1830); B. iteratus (Sharp, 1887) as a new synonym of B. xanthomelas Solsky, 1868; B. latecinctus (Sharp, 1885) as a new synonym of B. iridescens Solsky, 1868; and B. mexicanus Solsky, 1864 as a new synonym of B. viridipennis Baudi di Selve, 1848. Lectotypes were designated for: Belonuchus cariniventris Bernhauer, 1918; Philonthus trochanterinus Sharp, 1885; Philonthus zunilensis Sharp, 1885; Belonuchus jalappensis Bernhauer, 1917; Philonthus iteratus Sharp, 1887; Belonuchus nigerrimus Bernhauer, 1918; and Belonuchus pectinipes Bernhauer, 1910. The Mexican species of Belonuchus are mostly recorded from cloud forest (60%), oak forest (51.1%) and oak-pine forest (46.6%).
贝隆努斯是细胸隐翅虫亚科（隐翅虫科，隐翅虫族）中的一个多样性属，其中一些物种经常被采集。对于大多数墨西哥贝隆努斯物种，在最初描述后，几乎没有或没有报道过分类学信息。出于这个原因，基于对保存在几个墨西哥和国际收藏中的标本的研究，对墨西哥贝隆努斯物种进行了分类修订。我们提出了八个物种群来容纳墨西哥物种，其中五个物种群由一个独特的诊断特征支持。包括了每个物种群的物种的检索表和照片以及诊断结构的绘图。还包括了对 29 个已知物种的重新描述，16 个新物种的描述，以及关于种内二型性和大小变化的信息，两个新的国家记录（墨西哥和危地马拉）和 26 个新的州记录。我们提出了 B. xanthopus Solsky, 1868 和 B. celatus (Sharp, 1885) 作为 B. connexus (Say, 1830) 的新同义词；B. iteratus (Sharp, 1887) 作为 B. xanthomelas Solsky, 1868 的新同义词；B. latecinctus (Sharp, 1885) 作为 B. iridescens Solsky, 1868 的新同义词；以及 B. mexicanus Solsky, 1864 作为 B. viridipennis Baudi di Selve, 1848 的新同义词。为以下物种指定了模式标本：贝隆努斯 cariniventris Bernhauer, 1918； Philonthus trochanterinus Sharp, 1885； Philonthus zunilensis Sharp, 1885； 贝隆努斯 jalappensis Bernhauer, 1917； Philonthus iteratus Sharp, 1887； 贝隆努斯 nigerrimus Bernhauer, 1918； 和 贝隆努斯 pectinipes Bernhauer, 1910。墨西哥贝隆努斯物种主要记录于云雾林（60%）、栎林（51.1%）和栎松林（46.6%）。
