Brevimulticaecum scleropagi sp. nov. (Ascarididae: Nematoda) from the fish Scleropages jardini in Papua New Guinea

Summary

Examination of ascaridoid nematodes from the osteoglossid fish Scleropages jardini in Papua New Guinea revealed that they belong to a new species and named Brevimulticaecum scleropagi nov. sp. Multicaecum heterotis Petter, Vassiliades and Marchand, 1979 from the African osteoglossid fish Heterotes niloticus was moved to the genus Brevimulticaecum in new combination and reported from the same host in Nigeria and Sudan for the first time. The new species is near to B. heterotis but differs from it in having lips that are not lobed, in the absence of the cervical alae, the much smaller size and measurements of the various organs.
