Coloration. Base color translucent light pink or pink. Carapace and anterior half of abdomen orange, whitish along lateral margin, with pale longitudinal stripe flanking midline. P1 orange, with tips of spines whitish ( Baba et al., 2009). The specimens photographied in Vanuatu do not have the longitudinal stripes.

Remarks. The present material agrees quite well with previous descriptions (see Baba et al. 2009 and references). The material from Madagascar and identified as G. pubescens (Baba 1990, see below) belongs to G. villosa n. sp. The specimens from South Africa ( Tirmizi & Javed 1993) needs further study. Galathea pubescens is closely related with G. caesariata n. sp. from Papua New Guinea, Vanuatu and New Caledonia, G. crinita n. sp. from New Caledonia and Chesterfield Islands, G. tagaloa n. sp. from Fiji and Tonga, and G. villosa n. sp. from Madagascar, Mozambique, and Vanuatu (see Remarks of G. tagaloa and G. villosa ).

The genetic divergences between G. pubescens and other species are always higher than 16.8% (COI) and 8.5%, (16S rRNA) ( Tab. 2 ).

Distribution. Previous records from Japan to New Caledonia and off Central Queensland, 45– 494 m. Present records from the Philippines, Indonesia (Kei Islands), Vanuatu, New Caledonia, and Tonga, 170– 890 m.
