Genetic data. CO1; see Table 1 . Remarks. Originally described from off South Africa (off Natal), M. babai has subsequently been reported from shelf depths across the Indian Ocean as far east as Hong Kong ( Baba, 1988 ). It can be distinguished by the presence of spines on the anterior margin of abdominal somite 4 and very short supraocular spines. As noted by Baba (1988) , the number of spines on the abdominal somites is variable. We found abdominal somite 2 with 5–9 spines, somite 3 with 2–5, and somite 4 with 2–5 spines. The P2 dactylus is 0.75 the length of the propodus in Australian specimens compared to 0.64 for the type (based on Tirmizi and Javed, 1976: fig. 2D), and 0.84 for the Albatross material from Hong Kong and the Phillipines ( Baba, 1988 ). This is the first record of the species from Australia . Distribution. South Africa , Madagascar , Hong Kong , Malaysia , 70– 456 m . Western Australia, 100– 177 m .
