Trogulus

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. External morphology tends to be very uniform across species in the genus, making differentiation of species difficult. Species occur in a range of habitats, but are most common in forests where their primary prey, snails, are abundant. Trogulus contains the largest known harvestman by body length, Trogulus torosus.
