Etymology. The species is named for Nell Stoddart in honour of her good deeds and good spirit.

Diagnostic description. Head lateral cephalic lobe acute. Epistome and upper lip without a distinct notch between them. Mandible left lacinia mobilis peg-like. Maxilla 1 outer plate with 10 setal-teeth (not all visible in fig. 2) in a modified 7/4 arrangement; palp 2-articulate. Maxilliped palp article 2 about as long as broad, length 1 x breadth. Gnathopod 1 ischium long, length 3 x breadth; carpus shorter than (0.8 x) propodus; dactylus styliform. Pereopod 5 basis linear, without posterodistal lobe; merus posterodistal lobe reaching to about the end of carpus. Pereopod 7 basis posterodistal lobe extending slightly beyond ischium; merus posterodistal lobe extending beyond carpus. Epimeron 3 posterior margin minutely serrate; posteroventral corner subquadrate. Uropod 3 peduncle slightly longer than (1.5 x) ramus; ramus 1-articulate. Telson longer than broad, length about 1.1 x breadth, distally convex.

Habitat. Living on rock, rubble, clay, sand, biogenic sediment.

Remarks. Lepidepecreella nellae and L. tridactyla appear to be sister taxa and probably had a common ancestor 60 mya when Australia and Antarctica were still joined as part of Gondwana. The species have similar pereopods 5 to 7. The maxillipedal palp of L. nellae is stouter than that of L. tridactyla and the apical margin of the telson is rounded not truncated as in L. tridactyla .

Distribution. South-eastern Australia in 930–1000 m depth.
