Trogulus is a genus of Opiliones (also known as harvestmen) in the family Trogulidae.

Harvestmen in the genus have large, elongated and flattened bodies (prosoma and opisthosoma) and a two-segmented tarsus segment on leg II, which distinguishes them from other genera in the family Trogulidae.

The legs tend to be short compared to most harvestmen.

[1] External morphology tends to be very uniform across species in the genus, making differentiation of species difficult.

[2] Species occur in a range of habitats, but are most common in forests where their primary prey, snails, are abundant.
