Abstract

Psaironeura jeronimoi sp. nov. is described based on seven males (Holotype: ♂ (LABECO, N° 10002717), BRAZIL, Amazonas, Alto Maués Ecological Station, (-5.9852, -59.3182, 114 m asl, 12.v.2019) collected in the state of Amazonas (near Alto Maués Ecological Station) and Pará (municipality of Belterra). This new species fits into the tenuissima group but presents differences in color pattern and shape of the apex cerci. Main morphological characters are figured and compared with those of P. tenuissima (Selys, 1886) and P. bifurcata (Sjöstedt, 1918). Key to males and comments on genital ligula of the species of the group are provided. Finally, comments on the conservation status of the species are presented.

摘要

杰罗尼莫氏拟丽蝇 Psaironeura jeronimoi sp. nov. 是基于 7 只雄性个体（模式标本：♂（LABECO，编号 10002717），巴西，亚马逊州，上 Maués 生态站，（-5.9852，-59.3182，海拔 114 米，2019 年 11 月 12 日），采集自亚马逊州（上 Maués 生态站附近）和帕拉州（贝伦泰拉市）。该新种属于 tenuissima 组，但在颜色模式和尾须顶端形状上存在差异。主要形态特征被图示，并与 P. tenuissima（Selys，1886）和 P. bifurcata（Sjöstedt，1918）进行了比较。提供了雄性的鉴别特征和对该组种属生殖器 Ligula 的注释。最后，对该种的保护状况进行了评论。
