Maratus caeruleus Waldock 2013 

Maratus caeruleus  ( Figure 1 View Figure ), with a reported male body length of 7.89 mm, is perhaps one of the largest Maratus  ( Waldock 2013, Fig. 25 View Figure however depicts a body length ~5 mm). It is known only from type specimens collected on the ground (22 OCT 2008), on Middle Island in the Recherche Archipelago just 15 km from the type locality of the related M. avibus  ( Figure 13 View Figure ). Like the smaller M. avibus  , this spider lacks a central dark figure on the dorsal opisthosoma. Shallow seas presently separate this Archipelago from the mainland, but these were elevated areas on the mainland during the last glacial maximum (LGM, ~15- 20Ka). M. caeruleus  may represent a case of island gigantism (or the island rule; Lomolino 2005). Given the small size of Middle Island, a difference in selection based on community composition, as well as the rapid evolution (genetic drift) associated with a small island population ( Ellstrand and Elam 1993), may have led to a recent, rapid divergence of M. caeruleus  from the mainland species M. avibus  .
