摘要

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.
