Male and female of Nusalala peruanasp. nov., a flightless hemerobiid from the Andes mountain range of northern Peru, at a height of almost 4000 m, are described, figured and documented as the first record of a brachypterous, flightless species of Nusalala Navás, 1913, from this country. The other two congeneric, brachypterous species are from high altitudes in Colombia and Costa Rica and have been described in the male sex only – the females remain unknown. The coriaceous domed forewings are shared by all three brachypterous Nusalala species. The ribbon-like hindwings of the male of N. peruanasp. nov. are unique, since those of the other brachypterous males are scale-like, as are the hindwings of the female of N. peruanasp. nov. Distribution and evolutionary backgrounds of brachyptery and flightlessness in Neuropterida are discussed.

停泊在天地之间–来自秘鲁的新的不会飞的棕色lace（Neuroptera，Hemerobiidae）

男性和女性的Nusalala peruanasp。11月，来自秘鲁北部安第斯山脉的高度约4000 m的非飞行类杂种动物被描述，计算和记录为该国1913年NusalalaNavás的一种近距离飞行的非飞行种的第一个记录。另外两个同类的短足动物来自哥伦比亚和哥斯达黎加的高海拔地区，仅以雄性进行了描述，雌性仍然未知。刚球形的努萨拉拉物种共有三种。Peruanasp猪笼草的雄性的带状后翅。十一月 它们是独特的，因为其他短臂雄性的那些都是鳞片状的，而Peruanasp雌性的后代也是如此。十一月 讨论了翼龙科中近距离and行和失舞的分布和进化背景。
