Background Despite the widespread belief that an extensive body of knowledge exists for the sucking lice (Anoplura), some of their common, Eurasian or even cosmopolitan species still lack complete taxonomic descriptions, especially those for their nymphal stages. This applies especially to the most common rodent parasites: the lice of the genus Hoplopleura. In Europe, only two of the five most common Hoplopleura species have full taxonomic characteristics with a description of the nymphal stages. This study enriches the current state of knowledge for another species, Hoplopleura longula and presents the first description of its nymphal stages. The study includes five rare louse specimens (two nymphs I, one nymph II, two nymphs III) of H. longula collected from 63 Eurasian harvest mice Micromys minutus. The collected lice were fixed and preserved in 70% ethyl alcohol solution and then placed in polyvinyl-lactophenol to form total preparations. New information Only two of the five species found in Eurasia (H. acanthopus, H. affinis, H. captiosa, H. edentula and H. longula) have been given full taxonomic descriptions, including immature stages. This paper presents a description of the nymphal stages of H. longula (described for the first time).

从收获小鼠 Micromys minutus (Rodentia: Muridae) 中首次描述 Hoplopleura longula (Psocodea: Anoplura: Hoplopleuridae) 若虫阶段

背景 尽管人们普遍认为吸虱 (Anoplura) 存在广泛的知识体系，但它们的一些常见、欧亚甚至世界性物种仍然缺乏完整的分类描述，尤其是对于它们的若虫阶段的描述。这尤其适用于最常见的啮齿动物寄生虫：Hoplopleura 属的虱子。在欧洲，五个最常见的 Hoplopleura 物种中只有两个具有完整的分类特征，并描述了若虫阶段。这项研究丰富了另一个物种 Hoplopleura longula 的当前知识状态，并首次描述了它的若虫阶段。该研究包括从 63 只欧亚收获小鼠 Micromys minutus 中收集的长吻蝽的五个稀有虱子标本（两个若虫 I、一个若虫 II、两个若虫 III）。收集的虱子在70%乙醇溶液中固定保存，然后放入聚乙烯乳酚中形成总制剂。新信息 在欧亚大陆发现的五种物种中，只有两种（棘刺鱼属、亲缘鱼腥草属、鳞翅目鱼属、齿根鱼属和长齿鱼属）得到了完整的分类描述，包括未成熟阶段。本文介绍了 H. longula 的若虫阶段（首次描述）。
