Material examined. 13, AC, from Sargassum sp. , Ulva reticulata, La Cuvette (20°00'S 57°34.2'E), 5 May 1999; 3♀♀, 1 juv., AC, from Padina sp. and Halimeda sp. , Grand Baie (20°0.5'S 57°34'E), 5 May 1999.

Diagnosis. Gnathopod 1 carpus 1.3× as long as broad; propodus elongate, 1.9× as long as broad, anterior margin with dense groups of setae; palmar margin short, weakly crenulate; dactylus 1.6× length of palm. Gnathopod 2 carpus longer than propodus; palm oblique; anterior and posterior margin of carpus and propodus densely setose.

Female gnathopod 1 carpus cup-shaped, as long as broad; propodus 1.4× as long as broad, anterior margin with dense groups of setae; palm oblique.

Type locality. Tuléar , Madagascar .

Distribution. Madagascar, Mauritius, India.

Habitat. Globosolembos indicus was rarer among the substrates collected in the present study compared to G. excavatus . It was collected at depths of less than 0.5 m from two sites in the north coast among green and brown algae.

Remarks. The current material agrees with the descriptions of Ledoyer (1967: 133, fig. 18), Ledoyer (1982: 284, fig. 105) and Myers (1985b: 348–353, figs. 224–227). This species closely resembles G. excavatus and the pattern of chromatophores on the body segment is very similar. It is distinguished from the latter by the more setose anterior margin of the gnathopods 1 propodus in males and females, the lack of sternal processes on sternal plates 2–4, and the less reduced carpus in the male gnathopod 1.
