Distribution:

Only known from Hawaiian Islands (Hawaii, Maui), the Seychelles (Silhouette) and New Caledonia. New to Tristan da Cunha archipelago (Nightingale Island, Tristan da Cunha Island).

Description: See MENZEL & SMITH (2009): 41, figs 1.45– 1.47.

Discussion:

Although Pseudolycoriella setigera has currently been found only on three remote island localities, we suppose, that it is a widespread species. It only appears to be rare, because it does not occur in the Palearctic but possibly in the poorly studied Afrotropical Region. The occurrence on four different archipelagoes leads to the assumption, that it was also introduced by man.
