Acknowledgments Original efforts to describe this species were made by Professor Sixten Bock at the Swedish Museum of Natural History. His work was cut short by his death in 1946. Parts of his manuscript draft are included in the description from Cedhagen & Hansson (2012). [details]

Diagnosis From Cedhagen & Hansson (2012): "Body small, estimated maximal length 1.5 cm. Collar broader than long. Proboscis colouration light pink to golden yellow; collar white with transversal yellow bands; branchial, hepatic and intestinal regions translucent pale yellow to golden yellow; brown intestine visible through the body wall. Proboscis groove extends through posterior half of proboscis. Proboscis coelom large (1/3 to 1/2 of proboscis diameter). Stomochord extends through 1/4–1/3 of proboscis. The proboscis skeleton is well developed in its anterior part. It has a cup-shaped anterior part, and dorsal and lateral wing-like projections that support the stomochord and axial complex. Its two crura extend posteriorly into the collar around the oesophagus and slightly curve and taper. The left and right collar coeloms (mesocoels) are completely separated by dorsal and ventral septa (mesenteria). Nine to 17 pairs of gill openings, the size of the posteriormost successively smaller. The branchial skeleton is weakly developed and has no synapticles." [details]

Etymology From Cedhagen & Hansson (2012): "We dedicate this species in honour of Professor Sixten Bock (1884–1946), who discovered the species and made extensive studies of it." [details]

Length Estimated to be 1.5cm; value is estimated as no complete specimens have been collected.  [details]

Remark Noted to have a characteristic "medicine smell" by Sixten Bock [details]
