Feltia submontana (Köhler, 1961) is redescribed based on specimens from Northwestern Argentina and Central and Southeastern Brazil. Taxonomic comments, photographs of the adults, characters of taxonomic importance, and illustrations of structures of the labial palpus, legs, and male and female genitalia are provided. The species is compared with similar-looking and supposedly closely related species, such as F. hispidula (Guenée, 1852) and F. lilacina (Zerny, 1916). The species, originally described for Argentina, is reported for Brazil for the first time. Most Brazilian specimens come from the "Cerrado" but also from Southeastern Atlantic Forests. The life cycle of F. submontana specimens collected in Planaltina, Distrito Federal, Brazil, is described; the species probably has only a single generation per year and imagines are on the wing in the late autumn and early winter months; the last instar prepupa and pupa pass through aestival diapause. The abundance of F. submontana relative to other species of Agrotis Ochsenheimer, 1816, and Feltia Walker, 1856, in the above-cited locality is accessed through 4 years of standardized collecting with light trap; the species is the second most abundant species of these genera in the area, with about one fifth of the captures, second only to A. ipsilon (Hufnagel, 1766), with about two thirds of the captures, and about two times more abundant than F. subterranea (Fabricius, 1794); the latter two are regarded as important pest species in South America.
基于来自阿根廷西北部以及巴西中部和东南部的标本,对山地夜蛾(Feltia submontana (Köhler, 1961))进行了重新描述。提供了分类学注释、成虫照片、具有分类学重要性的特征,以及唇须、腿、雄性和雌性生殖器结构的图示。将该物种与外观相似且可能亲缘关系密切的物种进行了比较,如多毛夜蛾(F. hispidula (Guenée, 1852))和淡紫夜蛾(F. lilacina (Zerny, 1916))。该物种最初是针对阿根廷描述的,此次首次在巴西被报道。大多数巴西标本来自“塞拉多”,但也有来自东南大西洋森林的。描述了在巴西联邦区普拉纳蒂纳采集的山地夜蛾标本的生命周期;该物种可能每年只有一代,成虫在秋末和初冬月份出现;末龄预蛹和蛹经历夏季滞育。通过4年使用诱虫灯的标准化采集,评估了上述地点山地夜蛾相对于其他1816年奥克森海默描述的切根虫属(Agrotis)和1856年沃克描述的夜蛾属(Feltia)物种的丰度;该物种是这些属在该地区第二丰富的物种,捕获量约占五分之一,仅次于ipsilon切根虫(A. ipsilon (Hufnagel, 1766)),其捕获量约占三分之二,比地下夜蛾(F. subterranea (Fabricius, 1794))丰富约两倍;后两者被视为南美洲的重要害虫物种。
