A new troglobitic species of the subfamily Pselaphinae (Coleoptera: Staphylinidae), Tychobythinus inopinatus sp. nov., is described from Monello Cave (Syracuse, Syracuse Province, Sicily). Major diagnostic features are illustrated based on both male and female specimens. The new species shows some adaptations to cave life, i.e., pale brown colour; setation consisting of long and flattened setae and suberect shorter setae; absence of wings; and anophthalmy and elongate legs and antennae. It can be easily separated from the related taxa by the different shapes of the head, palpi, gular carina of the male, and aedeagus. Tychobythinus inopinatus sp. nov. is known only from Monello Cave, a limestone cave in the south-eastern Sicily.
隐翅虫亚科（鞘翅目：隐翅虫科）的一个新洞穴物种，意外隐肢隐翅虫，新种，采自莫内洛洞穴（锡拉库扎，锡拉库扎省，西西里岛）。基于雄性和雌性标本展示了主要诊断特征。新物种表现出一些对洞穴生活的适应性，即浅棕色；体表由长而扁平的刚毛和近直立的较短刚毛组成；无翅；无眼以及腿和触角细长。它可以通过头部、触角、雄性的喉隆线和阳茎的不同形状与相关类群轻松区分开来。意外隐肢隐翅虫，新种，仅见于莫内洛洞穴，西西里岛东南部的一个石灰岩洞穴。
