Type material. Ex P. plumosus, the Olive­winged Bulbul, holotype male, R. Panjang, MALAYA, 22 Dec. 1961, M­00780. Paratypes, all ex P. plumosus in MALAYA: 1 male, 1 female, same as holotype; 27 males, 26 females, same except 1 Dec. 1961 ­ 22 Nov. 1962, M­00568 to M­01926 (22 collections).

Other material. Ex P. melanicterus (J. F. Gmelin), the Black­crested Bulbul, 9 males, 9 females, THAILAND (11 collections). Ex P. brunneus Blyth, the Red­eyed Bulbul, 4 males, 2 females, MALAYA (3 collections). Ex P. s i m p l e x Lesson, the Cream­vented Bulbul, 2 males, 2 females, MALAYA (3 collections).

Remarks. The shape of the genital sac sclerite and the large dimensions separate the male of this species from others of the group. The female apparently is inseparable from those of M. phillipsi and M. gieferi other than by host association, with those of M. plumosi being found only in Thailand and Malaya and those of the other 2 species found primarily in the Philippines.
