Glorieusella gen. nov.

Type species. Thrombasia incerta Ledoyer, 1986 , by monotypy.

Etymology. The name Glorieusella refers to the Îles Glorieuses, the type locality of the type species.

Included species. Glorieusella includes one species: G. incerta ( Ledoyer, 1986) .

Diagnostic description. Antenna 1 flagellum article 1 lacking robust seta on distal margin; accessory flagellum forming cap. Antenna 2 flagellum articles 3–5 slender, without brush setae on the anterior margin. Mandibular incisor straight; molar (?) with reduced column and convex triturating surface (a button); palp attached midway. Maxilla 1 ST-7 and ST-D unknown. Maxilliped outer plate with (?) single apical robust seta. Gnathopod 1 parachelate; coxa large, nearly as long as coxa 2, not tapering; carpus slightly longer than propodus; propodus palm minute, transverse, straight. Pereopod 4 coxa with weakly developed posteroventral lobe. Uropod 2 inner ramus constricted. Uropod 3 rami without plumose setae in the female (male unknown). Telson weakly cleft.

Remarks. Glorieusella and Metambasia are the only genera of the Tryphosa group that have a minutely parachelate first gnathopod. They are easily separated, as Glorieusella has a large, non-tapering gnathopod 1 coxa, whereas Metambasia has a vestigial gnathopod 1 coxa.

Distribution. Indian Ocean.
