Remarks. The present specimens referred to M. typhle were recorded by Baba (1994) from central Queensland as M. magniantennulata . These two species are very similar overall, but the cheliped of M. typhle has spines present on the dorsal face of the palm and 2 lateral spines on the proximal half of the fixed finger, which are absent in M. magniantennulata . In addition, the P2–4 dactyli are longer in M. typhle (0.8 times the propodus compared to 0.5–0.6 in M. magniantennulata ); and abdominal somite 2 has 4 spines on the anterior ridge while M. magniantennulata has 2 spines. In the Queensland specimens examined here, the P2 dactylus has 7–8 spines along the flexor margin compared to the holotype of M. typhle , with 9 spines. The QM registration numbers published by Baba (1994) were listed incorrectly and have been corrected here. The ovigerous female (NMV J72915; Ahyong and Farrelly, 2019: fig. 98) collected during the recent Investigator voyage is much larger than most specimens collected previously. This large female differs from other specimens in lacking spines on the cheliped dactylus,and the spines on abdominal somite 2 are proportionally longer (similar in length to the branchial margin spines) and limited to the median part of the anterior ridge.

Distribution. Somalia coast, Seychelles, southern Madagascar, Taiwan, New Caledonia, Vanuatu, French Polynesia, 500–1940 m. Queensland, 1607–1761 m.
