Remarks. The material examined agrees with the original description by Baba (1972). The genetic divergences with other closely related species are always larger than 16.1 % ( COI, the closest is G. mauritiana  ), and 5.8 % (16 S rRNA, the closest is G. aegyptiaca  ) ( Tab. 1). Galathea maculiabdominalis  is morphologically closest to G. formosa De Man, 1902  but the two can be easily distinguished for one another by the following characters:

- The rostrum is longer than broad in G. maculiabdominalis  instead of broader than long in G. formosa  . - The anterior protogastric ridge is uninterrupted and reaches or nearly reaches the carapace lateral margins in G. maculiabdominalis  , whereas this ridge is interrupted and does not reache the carapace lateral margins in G. formosa  .

- The color patterns are very different. G. f o r m o s a has a whitish broad longitudinal stripe on the carapace ( De Man 1902; Baba 1977 c), that is absent in G. maculiabdominalis  ( Baba 1972; Poore et al. 2011).

G. maculiabdominalis  is also close to G. machordomae  n. sp. (see Remarks of the latter species).

Distribution. Japan (Ryukyus), Palau Islands, Philippines, Vanuatu, New Caledonia, and Fiji; 0– 80 m.
