摘 要:记述了寄生于北京猛禽体内的2种合饰带属线虫, 其中一种为新种,一种为中国新纪录种。标本保存于北京师范大学生命科学学院。红角合饰带线虫Synhimantus(Dispharynx)otisp.nov. (图1~7) 新种与Synhimantus(Dispharynx)capitata(Molin, 1860)和S.(D.)buccalis(GogoiandSarmah,1988)较相似,但新种在第5对肛后乳突内侧有1对无柄乳突,左交合刺末端分叉,饰带长而与S.(D.)capitata有明显区别。新种与S.(D.)buccalis的主要区别为肛后乳突5对,左交合刺短,颈乳突三叉状位于饰带之后,阴门位于体中之前。正模♂,副模♀,采自红角Otusscops(Linnaeus, 1758)的食道。词源:新种的种名来自宿主名。纵纹腹小合饰带线虫乌兹别克斯坦亚种Synhimantus (Dispharynx)noctuaeuzbekistanica(Sultanov,1950)中国新纪录(图8~10) 从纵纹腹小Athenenoctua(Scopoli,1769)的食道和口腔中采到3条雄虫。作者所采标本与Sultanov(1950)的原始描述基本相同,但前者饰带稍有波浪状的弯曲而原始描述为直的。Two species of Synhimantus (Dispharynx) were collected in birds of prey from the Beijing Raptor Rescue Center, Beijing, China. Synhimantus ( Dispharynx) oti sp. nov. in Otus stops resembles S. ( D.) capitata and S. ( D.) buccalis. The new species differs from S. (D.) capitara in having bifurcated end of left spicule, in having a pair of sessile papillae in the inner side of fifth postanal papillae, and in the length of cordons. It differs from S. (D.) buccalis in the numbers of postanal papillae, in the length of left spicule (470 vs 730) and ratio of spicules (1:3 vs 1:4), in the shape and position of cervical papillae, and in the vulva position. Synhimantus (Dispharynx) noctuae uzbekistanica (Sultanov, 1950) in Athene noctua (type host) differs from the original description in having slightly waved instead of straight cordons. This is the first report of this species in China.
