Revision of monozoic cestodes (Caryophyllidea) parasitic in commercially important walking catfish Clarias batrachus (L.) in tropical Asia (Indomalayan zoogeographical region) was carried out, based on the evaluation of newly collected material from India, Indonesia, and Thailand, as well as a study of type specimens. Instead of the 59 nominal taxa of 15 genera from 3 caryophyllidean families previously described, only 8 species of the Lytocestidae are considered to be valid: Bovienia indica (Niyogi, Gupta and Agarwal, 1982) n. comb.; Bovienia raipurensis (Satpute and Agarwal, 1980) Mackiewicz, 1994; Bovienia serialis (Bovien, 1926) Fuhrmann, 1931; Djombangia penetrans Bovien, 1926; Lucknowia microcephala (Bovien, 1926) n. comb.; Lytocestus indicus (Moghe, 1925) Woodland 1926; Pseudocaryophyllaeus ritai Gupta and Singh, 1983; and Pseudocaryophyllaeus tenuicollis (Bovien, 1926) n. comb. All valid species are redescribed and SEM photomicrographs of their scolices and photomicrographs of their eggs are provided for the first time. Crescentovitus Murhar, 1963, Heeradevina Srivastav and Khare, 2005, Pseudobatrachus Pathak and Srivastav, 2005, Pseudobilobulata Srivastav and Lohia, 2002, Pseudoclariasis Pathak, 2002, and Pseudoinverta Pathak, 2002 are invalidated and 50 nominal species are newly synonymized, including 4 species described from other fish hosts. Taxonomic status of the remaining caryophyllidean taxa reported from C. batrachus (at least 6 taxa) could not be clarified because of the unavailability of their original descriptions. A key to identification of caryophyllidean tapeworms parasitic in C. batrachus is provided. To avoid current inflation of descriptions of invalid taxa, researchers are strongly encouraged to work only with well-fixed material; damaged, decomposed, or strongly flattened specimens should not be used for taxonomic studies, and type specimens must always be deposited in internationally recognized collections.
基于对从印度、印度尼西亚和泰国新采集的材料以及模式标本的研究,对热带亚洲(东洋动物地理区)具有重要商业价值的胡子鲶(Clarias batrachus (L.))体内寄生的单殖绦虫( Caryophyllidea)进行了修订。先前描述的来自3个双叶目科的15个属的59个命名分类单元中,只有8种线绦虫科物种被认为是有效的:印度博维绦虫(Bovienia indica (Niyogi, Gupta and Agarwal, 1982) n. comb.);赖布尔博维绦虫(Bovienia raipurensis (Satpute and Agarwal, 1980) Mackiewicz, 1994);串联博维绦虫(Bovienia serialis (Bovien, 1926) Fuhrmann, 1931);穿透佐姆邦绦虫(Djombangia penetrans Bovien, 1926);小头脑库绦虫(Lucknowia microcephala (Bovien, 1926) n. comb.);印度利托绦虫(Lytocestus indicus (Moghe, 1925) Woodland 1926);里氏伪双叶绦虫(Pseudocaryophyllaeus ritai Gupta and Singh, 1983);以及细颈伪双叶绦虫(Pseudocaryophyllaeus tenuicollis (Bovien, 1926) n. comb.)。首次对所有有效物种进行了重新描述,并提供了它们头节的扫描电子显微镜照片和虫卵的显微照片。1963年的新月维图斯绦虫(Crescentovitus Murhar)、2005年的赫拉德维纳绦虫(Heeradevina Srivastav and Khare)、2005年的伪胡子鲶绦虫(Pseudobatrachus Pathak and Srivastav)、2002年的伪双叶绦虫(Pseudobilobulata Srivastav and Lohia)、2002年的伪胡子鲶吸虫(Pseudoclariasis Pathak)和2002年的伪无脊椎动物绦虫(Pseudoinverta Pathak)被认定无效,50个命名物种被重新归为同义词,其中包括从其他鱼类宿主描述的4个物种。由于无法获取原始描述,从胡子鲶报道的其余双叶目分类单元(至少6个分类单元)的分类地位无法阐明。提供了一个鉴定寄生在胡子鲶体内的双叶目绦虫的检索表。为避免当前无效分类单元描述的膨胀,强烈鼓励研究人员仅使用固定良好的材料;受损、分解或严重压扁的标本不应用于分类研究,模式标本必须始终存放在国际认可的收藏机构中。
