Genus Mizothenar Serov and Wilson, 1995

Mizothenar Serov and Wilson, 1995: 76 .

Diagnosis. Cephalon with short anterolateral tooth; antennal tooth absent; rostrum poorly de ned or absent. Eye consisting of rounded group of nine or ten ommatidia. Pereopod 1 in male, carpus not posterodistally produced; propodus expanded, as wide as long, palm bearing row of oblique dentate setae. Pleopod 2 in male distally widened, truncate.

Remarks. Two species of Mizothenar have been described: M. patulipalma (Kensley, 1984a) from Belize, and M. maharepa ( Müller, 1991e) from Moorea. The Caribbean species diVers from the latter species in lacking serrations or dentition on the lateral margins of the pleotelson. The female operculum in M. maharepa is distally more narrowed than in M. serratum , with the fused section about 1.8 times longer than the unfused part. In the latter species, the fused part is about 2.5 times longer than the unfused. These two species are remarkably similar, morphologically, and with no male material from the Indian Ocean, further comparisons are diYcult.
