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% (16S 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 1977c), 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 .
