Etymology "The genus is named to honor the late Dr. Nathan W. Riser in recognition of his careful study of one fauveliopsid species, where he clarified some anatomical features, and discovered the presence of genital papillae. The genus name is a free combination of the last name with the Greek suffix –iopsis. This suffix refers to a certain appearance or resemblance" (Salazar-Vallejo et al., 2019: 57). The authors are aware 'iopsis' names are usually intended for comparison to a similar genus, but are following the trend set by McIntosh when he created Fauveliopsis where the comparison is with a person.

Diagnosis "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). [details]Etymology "The genus is named to honor the late Dr. Nathan W.

Grammatical gender Feminine. A gender was not assigned by the authors, but the preceding Fauveliopsis, etc, genera have been treated as feminine, despite being named based on the family names of male taxonomists. [details]
