Morphological abnormalities in fleas seem to be common in nature and are under reported in Argentina. In this note, we describe anomalies in two males and one female of Alectopsylla unisetosa Mahnert (Ischnopsyllidae) and one of Polygenis sp. (Rhopalopsyllidae) male collected from small mammals in the provinces of Neuquen and Salta, Argentina. In all specimens, the anomalies were observed at the level of the genitalia recognized as partial castration. The structures mainly affected were the modified abdominal segments, the aedeagus (in male), and the spermatheca (in female). The present communication is the first one devoted exclusively to teratogenous fleas in Argentina.
跳蚤的形态异常在自然界中似乎很常见，但在阿根廷的报道却很少。在本说明中，我们描述了在阿根廷内乌肯省和萨尔塔省的小型哺乳动物中采集到的两只雄性和一只雌性的 Alectopsylla unisetosa Mahnert（蚤科）和一只雄性 Polygenis sp.（Rhopalopsyllidae）的异常现象。在所有标本中，观察到的异常现象都发生在被认为是部分去势的生殖器水平上。受影响的主要结构是变形的腹部节段、阳具（在雄性）和受精囊（在雌性）。本报告是专门针对阿根廷的畸形跳蚤的第一篇报告。
