Type material. Ex P. eutilotus , the Puff­backed Bulbul, holotype male, Semengo, SARAWAK, 14 Aug. 1966, 7E­0722. Paratypes, all ex P. eutilotus : 1 female, same as holotype; 2 males, 4 females, same except 8 Sept. 1966, 7E­0724; 3 males, 3 females, Pengkalanlobang Niah, SARAWAK, 28 Feb. 1967, 7E­1454; 9 males, 7 females, Subang, MALAYA, 19 Apr.­2 May 1962, M­01339 to M­01364 (4 collections).

Other material. Ex P. erythropthalmus (Hume) , the Spectacled Bulbul, 3 males, 2 females, MALAYA (3 collections), THAILAND (2 collections). Ex P. cyaniventris Blyth , the Grey­bellied Bulbul, 1 male, 1 female, THAILAND (1 collection).

Remarks. Both sexes of M. eutiloti are separated from those of M. plumosi by consistently being smaller in all dimensions. There also is a tendency for M. eutiloti to have reduced numbers of abdominal setae.
