Exosphaeroma laeviusculum

Exosphaeroma laeviusculum has a flattened body with speckled pattern of black and white, or pink. The pleon consists of a single segment, although the original fused segments are still discernible by lateral grooves. The telson is triangular, bears two small ridges near the base and a semicircle of tiny tubercles. Average body length is 10 mm.^[3]

The species occurs on the west coast of southern Africa, from Lüderitz in Namibia to Cape Point in South Africa.^[3][4] It inhabits the intertidal zone or shallow water, where it may be found among weeds or under stones.^[3]

For unknown reasons, the original description by Camill Heller reports the type locality as "Java".^[1][2]
