Remarks. Munida roshanei is reported for the first time from Australia. Our specimens have much longer supraocular spines (0.36 times rostrum length) than figured for the type (0.2 times rostrum length) (Tirmizi, 1966: fig. 13). Longer supraocular spines are also present on the specimen from the Red Sea illustrated by Lewinsohn (1969). Our specimens all lack a row of median gastric spines behind the rostrum, whereas the type has a row of 3 median gastric spines behind the rostrum, and in other specimens 1 or 2 spines are reported ( Baba, 1988; Tirmizi and Javed, 1993). There is clear sexual dimorphism in this species with males having large, gaping cheliped fingers. All of our specimens have cheliped fingers subequal to the palm in length.

Distribution. Indian Ocean (Gulf of Oman and Gulf of Aden, Red Sea, Andaman Sea and Mozambique Channel), and Phillipines, 16– 528 m. Western Australia, 93– 123 m.
