Hemitriakis sp. 1

Papuan Houndshark

Local synonymy: White et al., 2018: 118, figs (PNG).

PNG voucher material: None.

Remarks: First record for this genus in PNG waters; verified from photograph taken from a specimen caught and released off northern New Ireland in 2015. Possibly conspecific with an undescribed species from off Ghizo Island in the northern Solomon Islands. Although a genetic sample was retained from the two Solomon Islands specimens (Global Cestode Database www.tapewormdb.uconn.edu; G. Naylor, unpubl. data), no specimens were retained. Specimens required to confirm if the Solomon Islands and PNG individuals are conspecific and to describe the species.
