Tricholabus Thomson, 1894
Tricholabus is Holarctic, Indo-Malaysian, and Neotropical genus with at least 6 Nearctic species, one of which is undescribed (shown below). It was thought to belong to the Amlyteles genus-group due to the amblypygous female and the medial process on the male hypopygium, though it has been shown to be more closely related to the Callojoppa genus-group (Santos et al. 2021).
