Discosomaticinae

Roquettea singularis, copyright A. Anker.

Belongs within: Cosmetidae.

The Discosomaticinae are cosmetid harvestmen with pectinate claws on the hind two pairs of legs (Medrano et al. 2022).

Characters (from Medrano et al. 2022): Lateral borders of dorsal scutum following general body curvature. Pattern of white blots variable, mostly reticulated or punctate in Roquetteini, with a blurred ring in some Sibambea. Coxa IV usually covered by dorsal sutum so that only posterior margin is apparent. Tarsomeres of leg III seven or more, often nine. Tarsal claws of legs III–IV bipectinated (provided with two rows of denticles). Lateral patches of cteniform T4 microsetae restricted to corners of ventral plate. Wattle stylar barbs reaching ventral margin of stylus and forming a ventral peak.
