The Saldidae of the Hawaiian Archipelago
Cobben RH. 1980. The Saldidae of the Hawaiian Archipelago. Pacific Insects. 22(1-2):1-34
The following Saldula species are described from the Hawaiian Is: S. intermedia from Oahu, Maui and Hawaii; S. usingeri from Molokai and Maui; S. kauaiensis from Kauai and Oahu; and S. longicornis from Oahu. S. nubigena is known only from Maui. The remaining 3 Saldula species (exulans, oahuensis and procellaris) are widely distributed over most or all islands. Lectotypes are selected for S. exulans, S. oahuensis, S. procellaris, and S. nubigena. A revised key to all species is presented. The terminology of wing-morphs is discussed. Distributional patterns and extent of wing reduction, in addition to morphological differences, are used to reconstruct the probable relationships of the Hawaiian species in relation to evolutionary time. The 8 species known, all endemic, presumably arose from 3 independent invasions. S. exulans is supposed to represent the most recent introduction and S. nubigena the oldest. The latter species may be considered as the ancestor of 5 Hawaiian species.
