Euchone rubrocincta View in CoL .— Malmgren, 1866: 406.— Southern, 1914: 144.— McIntosh, 1916: 33; 1923: 282.

Material examined. Type material. Flor ø, Sogn og Fjordane [ ZMO, C2013, 4 syntypes].

Non-type material. Gullmaren [ ZMB 5723], Coll. Grube, Malmgren (1).

Diagnosis. Anal depression with lateral wings; vascular peristomial loops; ventral thoracic shields; eigth pairs of ventral radiolar appendages; dorsal pinnular appendages absent; dorsal lips elongate, collar ventral incised.

Remarks. Chone rubrocincta Sars, 1862 was transferred to Euchone by Malmgren (1866). Euchone analis and E. rubrocincta have vascular loops. According to Tovar-Hernández (2007), E. analis and E. rubrocincta have vascular loops, which are circular cameras situated dorso-laterally in the peristomium ; inside each camera there is an S- or C-shaped vessel; their structure and function has not been studied yet, but they might be irrigated from the central blood vessel. The vascular loops have been recorded also in Fabrisabella ( Fitzhugh, 1989) .
