Potamophylax humoinsapiens is a small caddisfly found in Kosovo. It belongs to the Limnephilidae family and was described in 2023 by Halil Ibrahimi and colleagues. It is most closely related to Potamophylax idliri and Potamophylax juliani.

This species is microendemic to the Šar Mountains in Kosovo, meaning it has a very limited geographic range. It was found at elevations between 1416 and 1505 meters in three different locations.

Male individuals have distinctive genital parts called parameres. They are elongated with a bulbous base that narrows toward the end, and the tip bears a cluster of thin spines like hairs. Potamophylax humoinsapiens can be told apart from close relatives by the noticeably wider gap between the dorsal and ventral edges of the inferior appendages when viewed from the side.

The name humoinsapiens comes from Latin humo (to bury) and insapiens (unwise). The researchers chose it partly because it sounds like Homo sapiens and to humorously remind people that human actions are threatening many insect species and ecosystems.
