| Abstract | A new species ofProteocephalus from the fishSinocyclocheilus grahami tingi, a subspecies endemic to Fuxian Lake in Southwest China,is described. This is the first report of cestode from this host. The new species differs fromP. exiguus, P. Longicollis, P. parasiluri andP. torulosus, the only other species ofProteocephalus currently reported from China, by lacking an apical sucker, fromP. exiguus by having 45–108 rather than 24–54 testes per proglottis, and a maximum of 15 rather than 28 uterine diverticula; fromP.longicollis by having an average of 45–108 rather than 75–115 testes per proglottis and testes being in a single layer instead of 2 layers; and fromP. torulosus by having 45–108 instead of 150 testes per proglottis and testes being in 3–4 layers; and fromP. parasiluri by having 45–108 rather than 180 testes per proglottis. It resemblesP. percae, P. pollanicola, andP. thymalli in number of testes and uterine diverticula, but differs by lacking an apical sucker.Proteocephalus thymalli, like the new species, has a vagina that opens dorsally to the cirrus sac, butP. thymalli slao has postovarian testes, which the new species lacks. The possible significance of parasitological examinations of the other two subspecies ofS. grahami in two lakes close to Fuxian Lake is discussed in relation to host speciation and coevolution of the host-parasite system. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
