Some species of Podisus Herrich-Schäffer have a confuse taxonomic history with several modifications and loss of information over time. The genus has been considered a taxonomic dumping ground in Asopinae, and its current species composition is doubtful. After examining the type specimens of Telepta distincta Stål, Arma submarginata Walker, Arma monospila Walker, Arma fuscescens Dallas, Arma caliginosa Walker, Arma turbida Walker and Podisus mellipes Bergroth, we redescribe and revalidate A. fuscescens as Podisus fuscescens rev. stat., previously considered a junior synonym of Podisus sagitta (Fabricius). The taxonomic status, morphology and distribution of P. fuscescens and P. distinctus are updated and illustrated. Arma caliginosa, A. turbida and Podisus mellipes become synonyms of P. fuscescens. Additionally, Arma submarginata Walker is removed from its synonymy with Podisus ventralis (Dallas) and treated as a synonym of P. distinctus. Podisus signoreti Fallou is removed from its synonymy with P. distinctus and treated as species inquirenda.
一些蠋蝽属（Podisus Herrich-Schäffer）物种有着混乱的分类历史，随着时间推移出现了多次修订且信息丢失。该属在蝽亚科中一直被视为一个分类学的“倾销地”，其当前的物种组成存在疑问。在检查了 Telepta distincta Stål、Arma submarginata Walker、Arma monospila Walker、Arma fuscescens Dallas、Arma caliginosa Walker、Arma turbida Walker 和 Podisus mellipes Bergroth 的模式标本后，我们将 A. fuscescens 重新描述并重新确认为 Podisus fuscescens rev. stat.，它之前被认为是 Podisus sagitta (Fabricius) 的次异名。更新并图示了 P. fuscescens 和 P. distinctus 的分类地位、形态和分布。Arma caliginosa、A. turbida 和 Podisus mellipes 成为 P. fuscescens 的异名。此外，Arma submarginata Walker 不再被视为 Podisus ventralis (Dallas) 的异名，而是被当作 P. distinctus 的异名处理。Podisus signoreti Fallou 不再被视为 P. distinctus 的异名，而是被当作有待进一步研究的物种。
