Handschin, 1942 is a pantropical genus of Pseudachorutinae with 18 species, 16 of which are from the Neotropical Region and 13 from Brazil. The genus has several species with unclear descriptions. Herein, we describe a new species of , survey the genus based on published papers and discuss its morphology, providing an updated genus diagnosis plus a detailed comparison table and a key to all known species. sp. nov. is unique in the combination of a postantennal organ with 14-20 vesicles, its mandible with five teeth, its maxilla apically pointed and its unguis with a pair of reduced teeth. Widely distributed taxa may be species complexes, especially due to their unclear descriptions.
汉德辛属（Handschin，1942）是伪阿霍鲁螨亚科（Pseudachorutinae）的一个泛热带属，有18个物种，其中16个来自新热带区，13个来自巴西。该属有几个物种的描述不明确。在此，我们描述了一个新物种，根据已发表的论文对该属进行了调查，并讨论了其形态，提供了一个更新的属诊断以及一个详细的比较表和所有已知物种的检索表。新物种在具有14 - 20个泡状结构的触角后器、具五齿的上颚、顶端尖的下颚以及具一对退化齿的爪等特征组合上是独特的。分布广泛的类群可能是物种复合体，特别是由于它们的描述不明确。
