Peristomial eyespots present. Glandular ridge on chaetiger 2 absent. Interramal eyespots absent. Superior thoracic notochaetae elongate, narrowly hooded, inferior thoracic notochaetae paleate; thoracic uncini avicular, with short handle, developed breast and several rows of progressively shorter teeth above main fang; neuropodial companion chaetae with denticulate head and long, gently tapering roughly symmetrical membrane. Abdominal uncini similar to thoracic ones; abdominal neurochaetae as elongate, broadly hooded chaetae. Pygidial eyespots present in juveniles (Nogueira et al. 2004).
