摘要(Abstract):

<正> 我们在贵州省的灰麝鼩Crocidura attenuataiMilne-Edwards,水麝鼩Chimmarogaleplatycephala himalayica Gray及大长尾鼩Soriculus(Chodsigoa)salenskii Kastschenko中检获五种吸虫,其中一种是新宿主纪录,四个新种,两个属是我国的新纪录。宿主名称依Ellerman & Morrison-Scott,1951订正,其汉名依《拉汉兽类名称》。量度为耗米,括弧内为平均值。
Altogether five species of trematodes are reported in this paper from shrews of Guizhou Province, four of which are new to sciense. 1. Neoglyphe linkuoliangi (Tang, 1941) n. comb. There were two species of plagiorhiid trematodes reported from shrews of China: i. e. Plagiorchis linkuoliangi Tang, 1941 and Opisthioglyphe cheni Sheng, 1965. The uterus of both species does not reach the posterior end of the body and their cirrus sac is of moderate length, hence they should be moved to the genus Neoglyphe of the family Omphalometridae, being Neoglyphe linkuoliangi (Tang, 1941) n. comb. and Neoglyphe cheni (Sheng, 1965) n. comb. respectively. Our specimens were collected from the small intestine of Crocidura attenuata Milne--Edwards from Guiyang. The gray shrew is a new host 2. Maritremioides congjiangensis Chin et Ku, sp. nov. Parasitic in small intestine of the water shrew, Chimmarogale platycephala himalayica Gray. Type and paratypes 32 specimens collected in Congjiang Xian, June 1963, deposited in the Department of Parasitology, Guiyang Medical Coellge. The new species is near Maritremioides mapaensis Chen, 1957 but differs in having longer prepharynx and cirrus sac, the ends of the latter curved posteriad to the level of middle of acetabulum. The intesinal crura are shorter, not reaching lateral limits of cirrus sac. 3. Carneophallus revolutus Chin et Ku, sp. nov. Parasitic in the small intestine of the water shrew, Chimmarogale platy- cephala himalayica Gray. Type and paratypes 8 specimens collected in Congjiang Xian, June, 1963, deposited in the Department of Parasitology, Guiyang Medical College. There were three species of mammalian Carneophallus (Yamaguti. 1971), namely C. turgidus Leigh, 1958, C. choanocephallus Bridgman, 1969 and C. basodactylo- phallus Bridgnan, 1969, all were parasites of Procyon loter, while C. choanoce- phallus also in Rattus rattus. Our species could be separated from them by the combination of the following characters. 1. The body is only slightly longer than broad and appears more rounded then the ordinary pear-shap. 2. The posterior border of body folds ventrally, forming an arched channel, hence it is named. 3. The intestinal crura are heavy and long with their posterior extremity beyond testes. 4. Vitellaria round, with 6--8 large follicles forming a single row along each side. 4. Xiphidiotrema magnum Chin et Ku, sp. nov. Paraasitic in the small intestine of the water shrew, Chimmarogale platy-- cephala himalayica Gray, Gongjiang Xian. Type and paratype one specimen each collected June 1963, deposited in the Department of Parasitology, Guiyang Medical College. Only two specimens were collected from the same water shrew harbored the previouse 2 species of trematodes. The only species of this genus, X. lockerae Senger, 1953 was collected from the intestine of shrews in U. S. A. Our specimens are much larger in size, oral and ventral suckers are about epual. The pharynx is larger than the oral sucker, on which the larval stylet is lacking. Ovary is smaller than oral sucker. Vitellaria follicles are also smaller. Yamaguti (1958) removed Xiphidiotrema from Nanophyetinae to Nephro- trematinae and pointed out that the location of both the testes and ovaryis an exception in the family Troglotremaidae Although this family has been divided into 4 subfamilies (Yamaguti, 1975), we, judging from the desposition of the gonads, suggest to raise Nephrotrematinae to full family rank, Nephrotre- matidae, which contains the genera Nephrotrema Bear, 1931, Xiphidiotrema Senger, 1953 and Soricitrema Bychowskaya-Pavlovskaya, Vysotzkaya et Kulakova, 1970, all being parasites of shrews. 5. Concinnum soricis Chin et Ku, sp. nov. Parasitic in gall bladder of the long-tailed shrew, Soriculus (Chodsigoa) salenskii Kastshenko. Type and 5 paratypes collected in Kuankuo Shui Natural Reserve, Suiyang Xian, Oct. 10th, 1976, deposited in the Department of Parasitology, Guiyang Medical College. Yamaguti (1971) listed 8 genera under mammalian Eurytrematinae. But the distinguishing characters of all these genera were more or less confusing. Our species is near both the genera Concinnum or Conspecuum. Because of the shorter oesophagus, the lacking of uterine coils between ovary and the testis of the same side and the presence of uterine coils in front of acetabulum, we put it under Concinnum. On the other hand, although the vitellaria are limited, yet they are arranged in a short row instead of in triangular groups. The genus Concinnum mainly parasitizes mammals while Conspecuum usually in birds. Therefore we prefer to classify our specimens as a new species under Concinnum. Concinnum soricis sp. nov. may be separated from all other species of the genus by the following combined characters. 1. The body is divided into a narrower anterior portion and a foliate hind portion. 2. The diameters of the oral and ventral suckers are about equal; 3. The testes are lateral to acetabulum or only slightly posterior to it; 4. The cirrus is club-shaped and 5. The vitellaria form longitudinal row lateral to intestinal crura.
