Several species of lady(bird) beetles have been purposefully and inadvertently introduced for more than 100 years in the Hawaiian Archipelago. Here, we report new state records for two lady beetle species in Hawai‘i, 20 new island records associated with 14 lady beetle species, and prey information associated with eight records. The update includes new geographic distribution records from five of the eight main islands and the Northwestern Islands of the Hawaiian Archipelago. New state records are reported for Delphastus pallidus LeConte, 1878 and Novius pumilus (Weise, 1892) in Hawai‘i. New island records are reported for Brumoides suturalis (Fabricius, 1798); Cycloneda sanguinea sanguinea Linnaeus, 1763; Diomus roseicollis (Mulsant, 1853); Hyperaspis connectens (Thunberg, 1808); Hyperaspis silvestrii Weise, 1909; Nephaspis bicolor Gordon, 1982; Nephus roepkei (Fluiter, 1938); Psyllobora vigintimaculata (Say, 1824); Rhyzobius lophanthae (Blaisdell, 1892); Scymnobius bilucernarius (Mulsant, 1850); Scymnus (Pullus) latemaculatus Motschulsky, 1858; Serangium maculigerum Blackburn, 1892; an undetermined Pharoscymnus sp. previously recorded in Hawai‘i; and an undetermined Sticholotis sp. previously reported from Hawai‘i. We report Laos as a new country record for the Sticholotis sp. Prey records are documented in Hawai‘i that include Tetraleurodes acaciae (Quaintance, 1900) for D. pallidus; Aleurodicus dispersus Russell, 1965 for S. maculigerum; Bemisia argentifolii Bellows & Perring 1994 and Metaleurodicus cardini (Back, 1912) for N. bicolor; Aleurotrachelus trachoides (Back, 1912) for N. indus and D. roseicollis; Aonidiella orientalis for R. lophanthae; and Aphis nerii Boyer de Fonscolombe, 1841 for S. latemaculatus. The new records demonstrate the value of ongoing sampling and regular examination of undetermined collections.
