The taxonomic status of (Latreille, 1811) is, by far, the most discussed within Triatominae. Molecular studies have recovered at least three independently evolving lineages in across its range. The original description of (as ) included few taxonomic characters, and no types were assigned. To define and describe the cryptic diversity within sensu lato (s.l.), a neotype must be designated. For this purpose, all 199 specimens identified as from the collections of the Smithsonian Institution - National Museum of Natural History and the American Museum of Natural History, ranging from Peru to Mexico, were studied. Only one specimen (from Tumbes, Peru) matched the combination of characters as listed in the original description, and it is herein formally designated as the neotype for . The neotype is morphologically described and DNA sequences of its whole mitochondrial genome and the nuclear second internal transcribed spacer region (ITS2), commonly used in triatomine molecular systematics studies, are presented and compared to other publicly available sequences of s.l. in GenBank. Our results suggest that sensu stricto (s.s.) is somewhat rare and, therefore, unlikely to serve as a major vector of Chagas disease.
（拉特雷耶，1811年）的分类地位是锥猎蝽亚科中至今讨论最多的。分子研究在其分布范围内的 中至少发现了三个独立进化的谱系。对 （当时为 ）的原始描述包含的分类特征很少，且未指定模式标本。为了定义和描述广义 （s.l.）内的隐性多样性，必须指定一个新模标本。为此，研究了史密森学会国家自然历史博物馆和美国自然历史博物馆收藏的所有199份被鉴定为 的标本，这些标本来自秘鲁到墨西哥。只有一个标本（来自秘鲁通贝斯）符合原始描述中列出的特征组合，在此正式指定其为 的新模标本。对新模标本进行了形态学描述，并给出了其完整线粒体基因组和核内第二转录间隔区（ITS2）的DNA序列，这两个序列常用于锥猎蝽分子系统学研究，并与GenBank中其他公开可用的广义 序列进行了比较。我们的结果表明，狭义 （s.s.） somewhat rare，因此不太可能成为恰加斯病的主要传播媒介。 （注：原文中“somewhat rare”表述似乎不完整准确，但按要求直接翻译）
