Plectromacronema Ulmer 1906 is a Neotropical genus recorded sparsely from South of Mexico to the North of Argentina. The genus is placed within the Macronematinae sub-family, members of which are relatively large among the Trichoptera and bears conspicuous wing ornamentations. There are only two species recorded for Brazil, Plectromacronema comptum Ulmer 1906 and Plectromacronema subfuscum (Banks 1920). Plectromacronema lisae Flint 1983 recorded for Mexico and Costa Rica is the only species in the genus with immature stages described. Immature stages species level identification is required for water quality biomonitoring and most of the Trichoptera taxonomy is based only on adult male genitalia. In this paper, we propose a new species, Plectromacronema solaris sp.nov., larva, pupa, and adult. Aspects of the life history of the new species are also discussed. This record also represents a new genus record for the state of Minas Gerais, extending the knowledge on the diversity, distribution, biogeography, and biology of this remarkable genus.
Plectromacronema Ulmer 1906 是一个仅在墨西哥南部到阿根廷北部有少量记录的新热带属。该属被置于 Macronematinae 亚科内，其成员在蜉蝣目中相对较大，并具有明显的翅膀装饰。巴西仅记录了两种，即 Plectromacronema comptum Ulmer 1906 和 Plectromacronema subfuscum (Banks 1920)。记录于墨西哥和哥斯达黎加的 Plectromacronema lisae Flint 1983 是该属中唯一具有描述的幼虫阶段的物种。为了进行水质生物监测，需要对幼虫阶段进行物种水平的鉴定，而大多数蜉蝣目分类学仅基于成虫雄性生殖器。在本文中，我们提出了一个新物种，Plectromacronema solaris sp.nov.，包括幼虫、蛹和成虫。还讨论了新物种的一些生活史特征。这一记录也代表了米纳斯吉拉斯州的一个新属记录，扩展了对这个引人注目的属的多样性、分布、生物地理学和生物学的认识。
