Abstract

Paracanthon Balthasar 1938 includes four nominal species of dung beetles occurring in the Atlantic Forest of northeastern, southeastern and southern Brazil, and Misiones, Argentina. Here we describe twelve new species of Paracanthon: P. arnaudi sp. n., P. belloi sp. n., P felipei sp. n., P genieri sp. n., P. grossiorum sp. n., P. laevinotus sp. n., P. lopesandradei sp. n., P. marinezae sp. n., P. millerorum sp. n., P.monteiroorum sp. n., P. muriloi sp. n., P. ocellatopunctatus sp. n. We propose P. pereirai d’Andretta & Martínez 1957 as a new junior subjective synonym of P. rosinae Balthasar 1942. In addition, we present new data on the morphology of the hindwings and male genitalia, and an identification key to the species of the genus. Paracanthon is restricted to the Atlantic domain, and we briefly discuss the possible processes that might have led to the diversification of the putative lineages recognized here.

Balthasar Paracanthon, 1938的分类订正(鞘翅目，金龟甲科，金龟甲科)

ParacantonBalthasar 1938包括发生在巴西东北部、东南部和南部以及阿根廷米西奥内斯的大西洋森林中的四种名义上的甲虫。在这里我们描述了副斑蝥属的十二个新种：P.arnaudisp。n.，P.belloisp。n.，P felipeisp。n.，P天才。n.，P.grossiorumsp。n.，P.laevinotussp。n.，P.lopesandradeisp。海军陆战队。n.，P.millerorumsp。n.，P.monteiroumsp.n.，P.muriloisp。n.，P.ocellatopunctatusp。n.我们提出P.pereirai d'Andretta&Martínez 1957作为P.rosinaeBaltasar 1942的一个新的初级主观同义词。此外，我们还提供了关于后翅和雄性生殖器形态的新数据，以及该属物种的鉴定钥匙。Paracanton仅限于大西洋地区，我们简要讨论了可能导致此处公认的假定谱系多样化的过程。

期刊介绍： Insect Systematics & Evolution (ISE) publishes original papers on all aspects of systematic entomology and the evolutionary history of both extant and extinct insects and related groups. Priority is given to taxonomic revisions and phylogenetic studies employing morphological and molecular data. ISE also welcomes reviews and syntheses that can appeal to a wide community of systematic entomologists. Single species descriptions, regional checklists, and phylogenetic studies based on few taxa or single molecular markers will generally not be accepted.
