Mayotte data
Menaethiops nodulosus (Nobili, 1905)
Material examined — Mayotte KUW 2009, st. 17, northern reef, suction pum in sediment, 22 m, 1 M 3.3 x 1.9 mm, 1 F ov 3.1 (tips of horns broken) x 2.1 mm, photo, MNHN B32566, MNHN-IU-2009-1326.
REMARKS — These two specimens were collected with suction pump in fine sediment. Despite of being very small they are mature specimens as indicated by an ovigerous female. The male pleopod is typical of Menaethiops (produced distally in two short triangular lobes). The determination is based on characters and figures in Nobili (1905), Guinot (1962b), and comparison with HD photograph of type specimens in MNHN-Collection (2018, MNHN-IU- 2014-19858). The carapace is pyriform, bumpy, with noticeable spine on the hepatic lobe; rostral horns are short, moderately divergent, the postorbital lobe is feebly serrated; there is a spine on the ocular peduncle.
GEOGRAPHIC AND DEPTH RANGES — WIO, Persian Gulf, Red Sea to Mayotte (this work), ?Réunion; subtidal to 22 m. A specimen from Réunion has also been examined (including male pleopod) and tentatively attributed to M. ?nodulosus by Legall & Poupin (2018)

Réunion data
Menaethiops nodulosus - Réunion. - Coll. BIOLAVE, 02/12/2011, shallow-waters, divers 10-30 m, pre-det. J. Poupin 25/01/2013. 1 M juvenile, pleopod correct for the genus.

Comment(s) on data
Réunion specimen: pleopod is typical of Menaethiops with 2 terminal lateral triangular lobes. Menaethiops natalensis is reported from Réunion but rostral horns are different in this species based on Peyrot-Claussade & Serène (1976, pl. I, fig. c).
