title: A Review of the Genera Dysanellus Bernhauer and Torobus Herman (Coleoptera: Staphylinidae: Staphylininae: Staphylinini)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Chatzimanolis, Stylianos (2018): A Review of the Genera Dysanellus Bernhauer and Torobus Herman (Coleoptera: Staphylinidae: Staphylininae: Staphylinini). The Coleopterists Bulletin 72 (2): 279-291, DOI: 10.1649/0010-065X-72.2.279, URL: http://dx.doi.org/10.1649/0010-065x-72.2.279ABSTRACTThe genera Dysanellus Bernhauer and Torobus Herman are illustrated and reviewed. Two species are recognized in Dysanellus, D. bruchi Bernhauer and D.transverserugosus Bernhauer.Two valid species are recognized in Torobus as well, T. laetipes (Bernhauer) and T. purpurascens (Nordmann) after the following taxonomic changes. Trigonurus brasilianus Bernhauer is recognized as a junior synonym of Staphylinus purpurascens Nordmann, new synonymy. Torobus mautnermarkhofi (Scheerpeltz) is transferred to Scariphaeus Erichson as Scariphaeus mautnermarkhofi, new combination. Synoptic catalogue entries are provided for all species that have ever been placed in either Dysanellus or Torobus to clarify the status of those species.Key Words: taxonomy, rove beetles, Trigonopselaphus, Terataki, Zackfalinus, XanthopyginaDOI.org/ 10.1649/0010-065X-72.2.279Zoobank.org/ urn:lsid:zoobank.org:pub: 38A07005-9DF6-4468-BBC3-BD16FE6851B4With 29 genera and more than 400 species, the subtribe Xanthopygina is a major radiation of rove beetles distributed in Central and South America. Xanthopygine rove beetles are typically large and colorful but not easily identifiable, even to the genus level. At least part of the problem has to do with the paraphyletic or polyphyletic status of many genera (e.g., Chatzimanolis 2014, 2015a; Chatzimanolis and Caron 2016) caused by early 19 th and 20 th century taxonomists who used certain genera as dumping grounds for species that could not be placed elsewhere.Two such taxa (at least until recently) were the genera Dysanellus Bernhauer and Trigonopselaphus Gemminger and Harold. Bernhauer (1911) described Dysanellus to accommodate D. bruchi Bernhauer, but both he (Bernhauer 1915, 1934) and others (Cameron 1933) subsequently placed in that genus several species that are not congeneric with D. bruchi. Countless specimens in natural history museums were identified incorrectly as Dysanellus sp. but later included as the recently described genus Zackfalinus Chatzimanolis (Chatzimanolis 2012). At least two keys (Navarrete-Heredia et al. 2002; Torres Rodr´ıguez et al. 2012) identify Zackfalinus species as Dysanellus.The taxonomic history of Trigonopselaphus is much more complicated than that Dysanellus and is described in detail in two recent publications (Chatzimanolis 2013, 2015a). Species that were placed in Trigonopselaphus prior to 2001 were split into two genera (Trigonopselaphus and Torobus Herman) by Herman (2001a). However, neither of these genera were monophyletic, and they were riddled with synonymies. Chatzimanolis (2013) described the genus Terataki Chatzimanolis to accommodate several species in Torobus, Trigonopselaphus, and Gastrisus Sharp. Subsequently, Chatzimanolis (2015a) revised the species that remained in Trigonopselaphus. The taxa that remained in Torobus after the description of Terataki were, unfortunately, still not a monophyletic group, and over the last several years I have written several papers to place them in the correct genera (Chatzimanolis 2017a, b).Given the extensive taxon reshuffling that has happened during the past few years in both Dysanellus and Torobus, the purpose of this review is to clarify the status of the remaining species in these genera and provide illustrations and descriptions for the identification of these species. Additionally, I provide synoptic catalogues for both genera to clarify the status of all species that once belonged in them.
