Type locality. East of Cape Naturaliste , Tasmania, Australia, 40°45.94’S 149°01.62’E GoogleMaps to 40°46.54’S 149°00.27’E, 2400–2500 m depth.

Etymology. The specific name refers to the vessel, Le Naturaliste , after which the nearest point of land to the type locality was named.

Diagnosis. Head lobe broadly rounded. Epistome strongly produced, broadly rounded, truncate ventrally. Gnathopod 1 propodus palm strongly acute, slightly concave; dactylus strongly over-reaching palm, with 2 subterminal spines on inner margin. Gnathopod 2 minutely chelate; propodus length 2.2 × breadth. Epimeron 1 anteroventral corner with a sharp inwardly-directed point. Epimeron 3 posteroventral corner broadly rounded. Uropod 2 inner ramus incised. Uropod 3 outer ramus article 2 long, 0.3 × article 1. Telson length 1.6 × breadth, cleft 58%.

Remarks. The Australian species H. naturaliste and H. franklin are the only species in the genus with the combination of a strongly acute palm on gnathopod 1 and a rounded posteroventral corner on epimeron 3. Hirondellea naturaliste differs from H. franklin in the strongly cleft (58%) telson, medium (40%) in H. franklin .

Distribution. East of Tasmania, Australia in 2400–2500 m depth
