Nereis falsa sensu Liñero-Arana & Reyes-Vázquez 1979

Nereis falsa – Liñero-Arana & Reyez-Vázquez 1979: 6, pl. 3 figs 1–13 (non de Quatrefages, 1866).

Diagnosis

Nereis with with posterior eyes completely exposed; longest tentacular cirri reaching chaetiger 8–10. Jaws with 7–9 denticles; paragnath formula: I: 1–3 in tandem; II: 22–34 in two rows; III: 28–35; IV: 34–40; V: 0; VI: 4; VII–VIII: 45–53 in 2 bands. Posterior parapodia with ventral ligules longer than neuracicular ligules and ventral cirri.

Material examined

None.

Remarks

Because no specimens were available, we cannot clarify the status for this record. There is a discrepancy between the description and the illustration regarding the tentacular cirri; in the illustration they reach about chaetiger 5, but the description indicated that they were twice as long. Based on the available data and by following the key below, the Venezuelan specimens resemble N. splendida Grube, 1840, by having anterior notopodial ligules digitate, median and posterior chaetigers with ventral ligules longer than neuracicular ligules and pharyngeal areas VII–VIII with 2–3 transverse rows of paragnaths. Their main differences are in the prostomial shape and the pharyngeal paragnath numbers in area II. In the specimens reported by Liñero-Arana & Reyes-Vázquez (1979) the anterior prostomial lobe is wider than long, and there are about 30 paragnaths in area II, whereas in N. splendida the anterior prostomial lobe is 2× as long as wide, and there are about 22 paragnaths in area II.

Distribution

Venezuela, Gulf of Cariaco, in intertidal rocky shores.
