Diagnosis. This species differs from Gabusibius ndzilu n. gen. n. sp. by its lighter color and from Gabusibius ? littoreus n. gen. n. comb. by the darker patterns. It differs from all Comorian species of Gabusibius n. gen. by male genitalia ( Figs. 68–70 ). Pseudepiphallus with parallel sides in the anterior half, converging in the last distal half; apex with a shallow notch separating two lobes (dorsal view); apex not elevated distally (side view). Epi-ectophallic invagination exceeding anterior projection of endophallic sclerite distinctly spoon-shaped (unlike Gabusibius ndzilu n. gen. n. sp.).

Description. In addition to generic characters. Color. Species with light background and black patterns ( Figs. 49–53 ). Body background color light yellow with black patterns; light triangle on the face distinct, with broad basis, narrow between antennae. Legs background color light yellow, patterns very distinct and black. Male. Stridulatory file with 52 teeth (paratype Mayotte.1 2010 135). SGP ( Fig. 54 ) broader than long (flattened). Genitalia ( Figs. 68–70 ). Pseudepiphallus with parallel sides converging in the last distal fifth; apex broadly rounded, not forming two lobes (dorsal view); apex not elevated distally (side view). Epi-ectophallic invagination exceeding anterior projection of endophallic sclerite; anterior part moderately concave, not spoon-shaped. Rami squared, very wide (side view), truncated anteriorly. Female. SGP hind margin with V-shaped emargination ( Fig. 56 ). OVP apex without narrow space between dorsal and ventral valves ( Fig. 56 ).

Biology. This species occurs on rocky beaches (mixed limestone and volcanic pebbles of small diameter). It can be observed by night hours, particularly at low tide.
