Type material. HOLOTYPE, female, 6.2 mm, MV J60572 View Materials . PARATYPE, 1 specimen, MV J15792 View Materials ; 76 km south of Point Hicks , Victoria, Australia, 38°29.33'S 149°19.98'E, 1840 m, sandy mud, fine shell, WHOI GoogleMaps epibenthic sled, 26 October 1988, G.C.B. Poore et al. on RV Franklin , stn SLOPE 69 .

Type locality. 76 km south of Point Hicks , Victoria, Australia, 38°29.33'S 149°19.98'E, 1840 m depth GoogleMaps .

Etymology. The specific name refers to the vessel, HM Bark Endeavour , on which Lieutenant James Cook was sailing when he named the nearest point to the type locality, Point Hicks; used as a noun in apposition.

Diagnosis. Head lobe broadly subtriangular. Epistome strongly produced, subtriangular with acute apex. Gnathopod 1 propodus palm transverse, straight; dactylus slightly over-reaching palm, with 1 subterminal spine on inner margin. Gnathopod 2 minutely subchelate; propodus length 2.2 × breadth. Epimeron 1 anteroventral corner rounded. Epimeron 3 posteroventral corner produced into large spine. Uropod 2 inner ramus not incised. Uropod 3 outer ramus article 2 long, 0.6 × article 1. Telson length 1.2 × breadth, cleft 38 %.

Remarks. Hirondellea endeavour is the only known Australian species with a transverse palm on gnathopod 1. However, H. abyssalis , H. antarctica , H. brevicaudata and H. guyoti all have transverse palms. Hirondellea endeavour shares a non-constricted uropod 2 inner ramus and a medium cleft telson with H. abyssalis and H. brevicaudata . It differs from both of these species in the posteroventral corner of epimeron 3 which is developed into a large spine.

Distribution. South-eastern Australia in 1840 m depth.
