Only one species is placed in the genus Monilothrips. Within the Panchaetothripinae, this resembles Hercinothrips in having the tarsi 2-segmented and in having two complete rows of setae on the forewing.
Larvae and adults feed on the fronds of various ferns, including Blechnum australe, Adiantum aethiopicum, Woodwardia sp., Polystichum sp., Pellaea andromedifolia.
Recorded from North and South India, South Africa, California (Wilson, 1975), and Hawaii (Mound et al., 2017), but the area of origin is not known; possibly either Africa or India,
