Neurisothrips antennatus (Moulton, 1928)

(Figs 1, 11, 15, 24, 39, 48)

Described originally from a single male taken on Oahu, Mt Tantalus, many specimens of both sexes of this species have been studied from Hawaii, Kauai, Lanai, Maui and Oahu. These specimens were collected from the flowers of Acacia koa, Astelia, Broussasia, Cheirodendron, and Geranium, and there are published records from Metrosideros . Both sexes are brown with teneral individuals considerably paler, particularly the males. The pronotum bears many discal setae, and the posteroangular setae are exceptionally long (120 microns), but the pronotal anterior marginal setae are all little longer than the discal setae. The tergal lateral discal setae are numerous (Fig. 39), and similar in number to multispinus, but antennatus is distinguished by the elongate antennal segment III that has almost parallel sides (Fig. 1). The fore wing is uniformly brown except for the usual sub-circular pale “window” near the veinal fork.
