Length 25-40 mm, width 2-3 mm. Prostomium with four curved nuchal arches. Body long tapering towards pygidium. Four pairs of branchiae. Paleae present, long golden extend past rim of prostomium. First abdominal segment with dorsal fan with large median notch. Remarks. The holotype of Jugamphicteis galatheae was collected from Kermadec Trench in the South Pacific Ocean ~ 4500 m; however, paratypes were recovered from both the Kermadec Trench and off the east coast of South Africa between Cape Town and Durban ~ 5000 m. The species is reported to have a wide distribution, which may indicate a species complex. Due to the matching morphology and close proximity of the specimens from this study to collection location of the holotype, we assign the name Jugamphicteis galatheae . Records. 40 specimens.
