This paper provides some observations on the anatomy of the neotropical katydid Arachnoscelis arachnoides Karny (Insecta: Orthoptera: Tettigoniidae). Arachnoscelis is a genus of predaceous katydids that comprise species that resemble spiders in their general body appearance. The type species, A. arachnoids, was described in 1891 from a single male collected in Colombia. Following the original description, these creatures were never found again, and were thought to have gone extinct or mistakenly assigned to the type locality. But between 1891 and 2012 four more species were described and in- correctly assigned to Arachnoscelis based on a similarity of body form. In this paper we present an anatomical comparaison of Arachnoscelis and its relatives, and propose that Arachnoscelis should be treated as a monotypic genus. This implies that other species previously described in Arachnoscelis, should be placed in different genera.
本文提供了关于新热带区螽斯蛛形螽斯蛛形亚种（蛛形螽斯）（昆虫纲：直翅目：螽斯科）解剖结构的一些观察结果。蛛形螽斯是一类捕食性螽斯，其种类在整体外形上类似蜘蛛。模式种蛛形蛛形螽斯于1891年依据在哥伦比亚采集到的一只雄性个体进行描述。在最初的描述之后，这些生物再也没有被发现过，人们认为它们已经灭绝或者被错误地归到了模式产地。但在1891年至2012年期间，又有另外四个物种被描述，并基于体型相似性被错误地归入蛛形螽斯属。在本文中，我们对蛛形螽斯及其近缘物种进行了解剖学比较，并提议将蛛形螽斯视为单型属。这意味着之前在蛛形螽斯属中描述的其他物种应被置于不同的属中。
