摘要

对南非夸祖鲁-纳塔尔省东北部Phongolo河淡水鱼进行了寄生虫学研究,发现了Wenyonia林地一新种,并对其形态和分子特征进行了分析。该新种来自于平原尖嘴鹬(Synodontis zambezensis Peters) (siluriforma: Mochokidae),在形态上与1923年在非洲东北部、西部和中部(苏丹、尼日利亚、刚果民主共和国)发现的三种尖嘴鹬(Synodontis acuminata Woodland)最为相似。这两个物种都有线虫状的身体和数字状的头节,明显不同于同类。细纹菊与尖毛菊的不同之处在于其总体体型、主要身体区域(睾丸和子宫区域)的长度和宽度、睾丸向子宫区域的后伸、充满整个髓质的大量卵黄卵泡、卵大1/3左右、头节内向,但没有纵向沟槽和明确的基部。gracilis Wenyonia是该属的第7种,也是非洲南部(赞比西河以南)报道和描述的第一个本土石竹属植物。

Wenyonia gracilis sp. n. (Cestoda: Caryophyllidea) from Synodontis zambezensis (Siluriformes: Mochokidae): the first native caryophyllidean tapeworm from southern Africa.

Parasitological examination of freshwater fishes of the Phongolo River in north-eastern KwaZulu-Natal, South Africa resulted in the discovery and morphological and molecular characterisation of a new species of Wenyonia Woodland, 1923 (Cestoda: Caryophyllidea). The new species from the plain squeaker, Synodontis zambezensis Peters (Siluriformes: Mochokidae), is morphologically most similar to Wenyonia acuminata Woodland, 1923, a species reported from three species of Synodontis in north-eastern, western and central Africa (Sudan, Nigeria, Democratic Republic of the Congo). Both these species are markedly different from congeners by having a nematoform body and a digitiform scolex. Wenyonia gracilis sp. n. differs from W. acuminata in its general body size, length and width of main body regions (testicular and uterine regions), a posterior extension of the testes into the uterine region, numerous postovarian vitelline follicles filling the entire medulla, eggs c. 1/3 larger in size, and a scolex with an apical introvert but devoid of longitudinal furrows and a well-defined base. Wenyonia gracilis is the seventh species in the genus and the first autochthonous caryophyllidean ever reported and described from southern Africa (south of the Zambezi River).

期刊介绍: FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
