""Fauveliopsids with body cylindrical, slightly swollen anteriorly, markedly swollen posteriorly. Anterior and posterior segments short, intersegmental grooves well defined; median segments long (as long or longer as wide). Integument mostly transparent, smooth, with minute papillae mainly near pygidium. Interramal papillae small, usually with a short stalk or sessile. Noto- and neurochaetae include uni- or bidentate aciculars, straight or falcate spinulose, and smooth capillaries in anterior and posterior regions. Median chaetigers with only one notoacicular chaeta. Pygidium non-retractile, often with small papillae, and large, falcate aciculars surpassing pygidial margin. Genital papillae unknown. Free living, sometimes in flexible, fibrous tubes, with or without foreign particles." (Salazar-Vallejo et al., 2019: 56-57)."
