- Pereopod 3 similar in length to P4 & 5 (sometimes also P6). Males with relatively thin, translucent cuticle (like females); pereonites without furrows.................................................................................. 9
8. Gnathopod 2; posterior margin of propodus with weak setae distally; dactyl relatively slender, not pressed against propodus. Pereopod 4 slightly shorter than P5, or sub-equal in length. Males; head with short lateral lobe at base of A1; pereonites with relatively deep furrows, especially for pereonites 1–4; telson length about one-third peduncle of U3.... M. colemani sp. nov.
- Gnathopod 2; posterior margin of propodus with pairs of strong setae; dactyl pressed against medial surface of propodus. Pereopod 4 slightly longer than P5. Males; head without lobe at base of A1; pereonites with slight furrows, barely noticeable on pereonites 5–7; telson length about half peduncle of U3...................................

Pereopods 3–5; propodus shorter than carpus, tapering distally................................................................................................ M. sphaericus Bovallius, 1885
- Gnathopod 2; propodus narrowing distally, with moderate postero-distal excavation. Pereopods 3–7 with relatively robust, curved dactyls.
