Nagurus nanus (Budde-Lund, 1908)


GB IUCN status: Not applicable (non-native)

ID Difficulty



This is a small species (to 5 mm) with an oval outline. The body is dark brown with two patches of pale yellow mottling situated either side of a broad dark brown central stripe (rather akin to that seen in our native Trachelipus rathkii).

It is readily identified from male pleopods. A description of this species, with figures, is given in Gregory (2014).

Distribution and Habitat

 A single specimen was collected from a heated glasshouse in Belfast Botanic Gardens in 1911 (Sutton, 1972).  The only subsequent record is of several specimens from Eden Project (Rainforest Biome), Cornwall, in 2005.

This species has been widely introduced throughout the tropics where it typically occupies disturbed habitats.
