Material examined. New South Wales: NMV J73001 , 3 ovigerous females (cl 10.6 mm, pcl 7.2 mm to cl 13.4 mm, pcl 12.5 mm), Central Eastern CMR, 30° 05.862' S, 153° 53.922' E to 30° 07.158' S, 153° 52.47' E, 2429–2518 m, IN2017_v03/086, 5 June 2017 .

Colour. Carapace, abdomen, cheliped and P2–4 pink. Eggs red.

Genetic data. Not available.

Remarks. The type specimens of M. magniantennulata are described as having the P2 dactylus 0.5–0.6 times propodus length, 6.6 times as long as high, and lined with 10 movable spines. Our specimens have a very similar P2 dactylus, which is 0.6–0.7 times the propodus length, 5–6 times as long as high, with 9–10 movable spines on the flexor margin. The chelipeds of all our specimens lack spines on the outer margin of the fingers or on the dorsal face of the palm, which agrees with the type material. All the specimens have two small tubercle-like spines on abdominal somite 2.

These specimens differ from the holotype in the length of the mesial spine on the first antennal article, which reaches the midlength of article 2 in these specimens but is very short in the holotype.

The specimens recorded by Baba (1994) as M. magniantennulata from off central Queensland are referred to Munida typhle Macpherson 1994 (see Remarks for that species).

Distribution. Lau Basin, 1750–2003 m. Eastern Australia, 2429–2518 m.
