Type material. Ex C. ochraceus , the Ochraceous Bulbul, holotype male, Chanthabari, Khao Soi Dao Tai, THAILAND, 12 Apr. 1966, MAPS­5095. Paratypes, all ex C. ochraceus in THAILAND: 19 males, 18 females, same except 11 Mar.–21 Apr. 1966, MAPS­4289 to MAPS­5259 (33 collections, not including MAPS­4300, 4510, or 4693); 1 female, Ranong, Muang Ban, 1 Dec. 1966, 7E­0533; 5 males, 3 females, Nakornsithamonaraj, Khao Luang, 14–28 May 1965, MAPS­143, MAPS­268 to MAPS­533 (5 collections).

Other material. Ex C. bres (Lesson) , the Gray­cheeked Bulbul, 7 males, 8 females, MALAYA (7 collections), SARAWAK (2 collections), THAILAND (1 collection). Ex C. pallidus Swinhoe , the Puff­throated Bulbul, 7 males, 7 females, THAILAND (8 collections). Ex Ixos mcclellandii (Horsfield) , the Mountain Bulbul, 6 males, 10 females, THAILAND (6 collections), MALAYA (6 collections). Ex Hemixos flavala Blyth , the Ashy Bulbul, 1 male, THAILAND.

Remarks. The unique shape of the male genital sac sclerite ( Fig. 12 ) sets this species apart from all others; quantitative features also support this separation. The female is only tenuously separable, with host association being the only certain feature of recognition.
