Mamoea grandiosa is a spider species described by Ray Forster and Cecil Wilton in 1973.[2] It was originally placed in the family Amphinectidae, but a large phylogenetic study by Wheeler et al. transferred the genus Mamoea to Desidae.[4] The type specimen is held at Te Papa.[2][3]
The carapace and chelicerae of Mamoea grandiosa are bright red brown, while the legs and sternum are orange brown. The abdomen has a broad grey band down the mid-dorsal (upper) surface with seven pairs of lateral branches on posterior (rear) half. The ventral surface of the abdomen is cream with a few scattered brown patches. The body length of both males and females is given as approximately 12 mm.[2]
Forster and Wilton not formally present a diagnosis for M. grandiosa but did note the distinctiveness of the female epigynum. Figures of the male palp are also implicitly diagnostic.[2]
The type locality for Mamoea grandiosa is Solomon Island / Rerewhakaupoko, south-west of Stewart Island / Rakiura. The holotype specimen was collected by Beverley Holloway during the 1955 Dominion Museum expedition.[3] It is also known from Stewart Island and the southern South Island of New Zealand.[2]
Mamoea grandiosa has been assessed under the New Zealand Threat Classification System and categorised as Not Threatened (NT).[5]
