Genus Laubieriopsis Petersen, 2000

Type-species: Fauveliopsis cabiochi Amoureux, 1982 , by original designation.

Diagnosis (emended after Petersen 2000, emendation in italics). Body short, linear, of similar width throughout, divided into two regions according to chaetation. Epithelium smooth, iridescent, mostly without papillae, or papillae minute and inconspicuous except for a few around the anus. Segments weakly defined externally; parapodial lobes absent, chaetae emerging from low welts or directly from body wall. Interramal papillae small, mostly sessile and inconspicuous. Chaetae include weakly curved uni- or bidentate aciculars, sigmoid aciculars and slender, flattened, smooth, pointed chaetae (capillaries). Aciculars with median rows of spines, being smooth basally and distally. Last segment well developed, similar in size to preceding ones, bilobed in dorsal and ventral views, often with elongated chaetae and a few papillae. Pygidium usually recessed within last chaetiger. Paired or unpaired genital papilla on anterior chaetigers.

Remarks. The generic diagnosis was emended to include the ultrastructure of the aciculars. SEM photographs have revealed that all aciculars have rows of spines, being smooth only near the base and distally (figs. 2E, 3D-E; Zhadan & Atroshchenko 2012: Fig. 4c).
