A new tapeworm, Postgangesia inarmata n. sp. (Eucestoda: Proteocephalidea: Gangesiinae), parasitic in Silurus glanis (Siluriformes) from Iraq and some comments on the Gangesiinae Mola, 1929

We describe a new species of cestode belonging to Postgangesia Akhmerov, 1969 (Proteocephalidea: Gangesiinae) from the catfish Silurus glanis Linnaeus in Iraq. This is the second species known from this genus, and a redescription of the type-species, P. orientalis Akhmerov, 1969 (emend.), as well as...

Description
Summary:We describe a new species of cestode belonging to Postgangesia Akhmerov, 1969 (Proteocephalidea: Gangesiinae) from the catfish Silurus glanis Linnaeus in Iraq. This is the second species known from this genus, and a redescription of the type-species, P. orientalis Akhmerov, 1969 (emend.), as well as a differential diagnosis are provided. The new species is characterised by the arrangement of its vitelline follicles, and various meristic and metrical characters. The systematic position of Postgangesia is discussed on the basis of both scolex and strobilar characters and arguments are presented for its placement within the Gangesiinae together with Electrotaenia Nybelin,1942, Gangesia Woodland,1924, Silurotaenia Nybelin, 1942 and Vermaia Nybelin, 1942. Finally, we illustrate and discuss some particular structures found in these taxa, especially in relation to the apical organs of the scolex.
