- W2389182055 abstract "A further study of Cyathocotylid trematodes from Fujian Province was undertaken. Collections and data were accumulated on this small group of trematodes. A new genus and three new species were described. The piscivorous definitive host of Prosostephanus industrius (Tu-bangui, 1922) (figs. 3, 6) was found to be Lutra hnra chinensis Gray. This normal host had been searched for more then 30 years.The genus Tangiella parovipara (Faust and Tang, 1938), Sudarikov, 1962 (fig. 4) by recollection of its history of discovery was found to be doubtful, because its host, Meles leptorhyn- chits probably got it by being fed in the zoo with Carassius carassius containing the cysts of P. industrius. The remaining specimens in our collection were found to be under-developed and abnormal. Therefore the name Tangiella parovipara is a genus and species inq.Diagnosis of Holostephanus rallus sp. nov. (fig. 1). Host: Amaurornis phoenicitrus chin-ensis (Boddaert); Location: Intestine; Locality: Fuzhou (26°2'N, 119°E) Cyathocotylidae, Cyat-hocotylinae. Body spindle shaped, 2.099-2.147 × 1.045-1.292 mm. Oral sucker terminal, 0.146-0.173×0.182- 0.213 mm. Pharynx 0.111-0.119×0.115-0.137 mm. Intestinal caeca reach to 1/3 body length posteriorly. Tribocytic organ with round ccncavity. Testes oblong in shape lying at posterior half of body. Cirrus pouch with an oval seminal vesicle and a long ductus ejacula-torius. Egg 0.099-0.106×0.053-0.059 mm. The present new species differs from related species, like H. luhei, H. corvi, H. metorchis, and H. curonensis in possessing a large and characteristic seminal receptacle, while H. ibisi also possesses a seminal receptacle, the organ is pointed at both ends. Its eggs are also smaller (0.075-0.078×0.048-0.057 mm).Fengcotgle gen. nov.Diagnosis of the new genus: Cyathocotylidae with no concavity on its ventral side, aceta-bulum entirely degenerated. Two testes lie obliquely on the central part of the body. Ovary lies anterior to left testis. Vitellaria occupying bothlateral positions of the tribocytic organ extending to its posterior end. Cirrus pouch lies horizontally and posteriorly to the testes at the posterior one-third to two-fifths of the body length, and opens at the cone like caudal end. Uterus with numerous eggs occupy the middle portion of the posterior half of the body. Type species: Fengcotyle hoeppliana gen. et sp. nov. (fig. 4). Host: Numenius arquata orientalis Brehm. Locality: Fuzhou. (26°2'N, 119°E).Diagnosis of the new species: With characteristics of the new genus. Body 1.938 × 1.795mm. Oral sucker subterminal, 0.209×0.199 mm. Pharynx 0.114×0.152 mm. Oesphagus 0.10 mm in length. Intestinal caeca terminated to posterior one-third of body length. Testes and ovary are situated in the middle part of body. Testes 0.513×0.280 mm and 0.323×0.316 mm. Ovary 0.171 mm in diameter. Vitellaria very extensive occupying both lateral sides of body. Cirrus pouch lies horizontally enclosing a seminal vesicle and a long ductus ejaculatorius and cirrus leading to the caudal genital cone at the left side of body. Eggs 0.111-0.119×0.066-0.088 mm.Furcocercaria yungangensis sp. nov.(figs. 6)Molluscan host: Parafassarulus striatulus; Locality: Yungan, (26°N, 117°24'E) Fujian. Description: Mature sporocyst 2.00×0.25 mm with cercaria with furcocercus tail. Body oval or pear-shaped, 0.126-0.145× 0.069-0.080mm. Tail stem 0.197-0.241× 0.027-0.034 mm. Tail furci 0.161 -0.184×0.011 -0.017mm. Body covered with minute spines. Oral sucker surrounded with 6-7 circlets of spines. Oral sucker 0.038 × 0.025 mm. Prepharynx short. Pharynx 0.013×0.01 mm. Length of oesophagus 0.012mm. Acetabulum shows sign of degeneration, situated before the excretory bladder and the inner excretory tubules. Excretory formula. 2[(2 + 2) + 2+(2)] =16. This formula differs from all known excretory formulas recorded for the cerarie of the family Cyathocotylidae.By experimental infection of laboratory reared gold-fish, 4 days later metacercarial cysts were secured. The cyst contains two walls, the inner one and an outer one which is" @default.
