WA Museum Records and Supplements | Updated 1 decade ago

Abstract: Collections obtained by the author in Papua New Guinea during 1982-83 contain two new species of plotosid catfishes. Oloplotosus torobo is described from two specimens collected at Lake Kutubu, Kikori River system. It is closely related to O. mariae from the Lorentz and Fly River systems of southern New Guinea but differs in fin ray, vertebral, and gill raker counts. Tandanus coatesi is described from 60 specimens obtained in foothill tributaries of the Sepik River. It is allied to T. gjellerupi and T. equinus from northern and southern New Guinea respectively, but differs in shape and counts of fin rays, gill rakers, and vertebrae. Detailed descriptions and illustrations are provided for the two new species.
