摘要
于云南屏边县杜氏泛树蛙PolypedatesdugriteiDavid膀胱内检获单殖吸虫多盘科多盘虫属 1新种 :屏边多盘吸虫Polystomapingbianensissp .nov .,对其形态结构及宿主特异性问题进行了初步研究。据宿主膀胱内寄生的产卵成虫测量形态分类数据和描述鉴定特征。虫体全长平均 9 4 2 8mm ,后吸器大小平均 0 86 9mm× 0 784mm ,后吸器吸盘的直径平均 4 34 4 μm ,后吸器上两个中央大钩全长平均 4 0 3 2 μm。朝向外侧肠管无盲突 ,朝向内侧肠管每侧形成 1 3～ 1 4个盲突 ,有 1个或无过腹中线的肠联合 ,肠管于后端合并向后延伸至后吸器内 ,不形成盲突。卵巢较小 ,位于单个睾丸之前 ,卵巢长平均 71 1 5 2 μm。卵相对较大 ,卵长平均 30 6 6 μm ,卵宽平均 1 6 4 6 μm。
Polystoma pingbianensis sp. nov. is described as a new species of the Polytomatidae(Monogenea) genera Polystoma parasitic in the urinary bladder of the host Polypedates dugritei David. The host were obtained during Apr. and May in 2002 at Pingbian County (22°56′N, 103°42′E), Yunnan Province, China. The hosts were collected from bushes and water at some marshy area near a slow flowing pool. Holotype and paratypes deposited in the Zoological Research Room of School of Life Science of Yunnan Normal University,Kunming. The preliminary structure and speciality of host of the new species are discussed in this article.The main characteristics and measurements of adults based only on egg producing bladder parasites. Mean total body length 9 428?mm, haptor 0 869?mm×0 784?mm, sucker diameter 434 4?μm and mean haptoral hamulu total length 403 2?μm.The outside lateral intestine completely absence of anastomoses, but 13 14 medial intestinal diverticular branched, extending well beyond mid line and form 1 anastomoses with the opposite diverticular, or form no anastomoses usually. Lateral intestine extending well into haptor and form no diverticula. Ovary is smaller, mean length 711 52?μm and ovary anterior to single testis. Eggs relatively large, mean egg length 306 6?μm, mean egg diameter 164 6?μm.
