    Abstract: A new species Myxobolus guanqiaoensis was found in the liver and abdominalcavity of Allogynogenetic silver prassian carp at Guanqiao, in Oct l996. The typespecimens were preserved in the Laboratory of Hsh ixseases, Inshtute of Hydrobiology,The Chinese Academy of Sciences, Wuhan, China.apcobolus guanqiaoensis sp. nov.Host and site: Allogynogenehc si1ver crucian carp (Carassius auratus gibelio ♀ × CyPrinus carpio J), Liver and abdowhnal cavity. Locality: Guanqiao, Wuhan, China.Infechon ratet above 6o%.Cystt Oval or elliptic in form, white in color; 2.l-4.Ocm in diametef, embracedby a tf8nsparent membrane.Sporest Spores elongatedsioval in thecal view. Pointed at anterior end and blunhyround in posterior end; l-3 V-shaPed folds at posterior end; elongated elliphc insutural view, sutural line S-shaped and dishnct shell valves smooth; intercapsularal Pendix dishnct. Two polar capsules eggplant unequal in size, polar capsule locatedat l/2 position of spore length; 7-8pm flat coiled filament Dimensions of 20 fresh spores: length l9.6(l8.2-22.0)?. width 10.8(9.O-l3.2)?. thickness 8.3(8.O-9.o)?, large po1ar capsules 9.5(8.8-lO.1) by 3.7(3.O-4.4)?,small polar capsules 8.4(7.9-9.8) by 3.6(3.2-4.O)?. Polar capsule nuclei situated atthe inner of two polar capsules. An indistinct iodinophilous vacuole and two roundgerminal nuclei.The shape of trhis new species is similar to Myxobolus gigi, Myxobolus koi and Myxobolus aureatus, but differs from them in dimensions of spore, the size of Polarcapsule, suture line and host.
