Lychaete robusta Areschoug, 1851: 8 (type locality: Cape of Good Hope, South Africa).
Chaetomorpha robusta (Areschoug) Papenfuss, 1940a: 200–201.
Misapplied name:
Chaetomorpha clavata.—Barton, 1893: 54.
Note: Areschoug, when describing Lychaete robusta, gave Algoa Bay as one of the localities. Barton repeated this record under the name Chaetomorpha clavata. Papenfuss (notes) was unable to find a specimen of L. robusta from Algoa Bay in Areschoug's herbarium (in S). He concluded that this species is restricted to cold water (west of Cape Agulhas).
