Bradophila pygmaea Levinsen, 1878 (Figs. 9–10, 11A) Bradophila pygmaea Levinsen, 1878 —incorrect original spelling. Bradophila pigmaea Levinsen, 1878 — Marchenkov (1999a: 108, 109, 111, 112, Figs. 34, 35; 1999b: 7, 8, 22, Table 1; 2002: 514, 516, 517): incorrect subsequent spelling. Bradophyla pigmaea Levinsen, 1878 — Marchenkov (1998: 15; 1999b: 13, Table 3; 2001: 97; 2002: 517): incorrect subsequent spelling. Bradophyla pigmae Levinsen, 1878 — Marchenkov (2001: 90, 97): incorrect subsequent spelling. Levinsen (1878) discovered four females, of which two were ovigerous, among museum collections of the flabelligerid polychaete Brada villosa. His text description in old Danish and accompanying woodcut figures are remarkably detailed by contemporary standards and reveal details that were even overlooked in modern descriptions (e.g. Marchenkov 1999b, 2002). Contrary to Marchenkov’s (2002: 514) claim that the hosts were collected off the coast of Greenland by Steenstrup and Lütken no locality data were given (although note that some of the parasitic copepods described in Levinsen’s (1878) work did indeed originate from Greenlandic waters, e.g. Selioides bolbroei, Melinnacheres terebellidis). According to Levinsen the egg sacs of ovigerous specimens extended into the “mouth cavity” of the host while the body was surrounded by, and probably embedded into, the anterior part of the annelid’s alimentary tract. Levinsen (1878) doubted whether he had dissected the entire parasite out of the host and his illustrations appear to confirm that he had only obtained the ectosoma. Hansen (1892, 1897) had previously suspected that some tubes must run into the body of the host, otherwise it would be difficult to see how the parasites obtain their food. The second report on B. pygmaea is that by Marchenkov (1997) who recorded a single ovigerous female from Brada villosa in the Chupa Inlet of the Kandalaksha Gulf, White Sea; no morphological observations were provided. In a conference abstract Marchenkov (1998) subsequently announced ...
