Colour: Body brown-orange; last abdominal segments and telson whitish; rostrum bordered by white or light brown band; pereiopods light brown, dacyli whitish.

Remarks. As pointed out by Baba (1988), M. cylindrophthalma shows variation in the shape of the rostrum and in the length of the corneae. Furthermore, the material from Indonesia has the dorsal side of the rostrum clearly concave, and the cornea is longer than the remaining eyestalk, exceeding the third antennal article. The specimens from other localities have the rostrum dorsally convex.

Distribution. Arabian Sea, Maldives, Andaman Sea (type locality), W of Sumatra, Japan (Tosa Bay, off Akabane), Taiwan, Philippines, Indonesia (Kei Islands), between 188 and 1475 m. The present material extends the distribution range of the species to Solomon Islands, Vanuatu, New Caledonia and Fiji, between 299 and 854 m.
