Galeus corriganae sp. nov., a new species of deepwater catshark (Carcharhiniformes: Pentanchidae) from Papua New Guinea

A new species of catshark, provisionally placed in the genus <em>Galeus</em>, is described from Papua New Guinea based on 7 specimens collected during recent deepwater surveys of the region. The new species, <em>Galeus corriganae</em>, is closest to <em>G. priapus </em>from New Caledonia and <em>G. gracilis </em>from northwestern Australia but differs in several morphological characters. A reclassification of the catshark groups is required to revise the familial and generic arrangement of the group
