Marphysa macintoshi Crossland, 1903

Marphysa macintoshi Crossland, 1903: 137, Plate XIV, figs 3–6.— Fauvel, 1919: 380.— 1930: 28.— 1953: 244, 246.

Material examined. None.

Remarks. Glasby & Hutchings (2010, see Table 2) provided a list of the diagnostic characters for this based on syntypes (BMNH 1924.3.1.22-23) and type description. Branchiae present starting from chaetigers 30 to 52, to posterior (syntype lacking last few segments), pectinate chaetae present from anterior segments, all asymmetrical, and compound spinigers present after chaetiger 110, and subacicular hooks simple, not bidentate.

Fauvel (1932: 141) while including M. macintoshi in his key to species of Marphysa, noted that it was recorded from Krusadai Island, Gulf of Manaar, but was not represented in the collections (presumably he is referring to those of the Indian Museum). He repeated this record in his 1953 publication, where he stated that the chaetae and branchiae are as in M. sanguinea (Montagu, 1813) . We suggest that with no voucher material, the record from Krusadai Island cannot be substantiated, and probably represents another undescribed species.

Type locality. Zanzibar, collected in sand intertidally from both the east and west coast of Zanzibar.
