description: Neurisothrips robbiei sp. n.
(Figs 7, 16, 23, 28, 29, 34, 43, 47)
Female. Body almost bicoloured, head with postoccipital area dark but anterior half almost yellow; thorax yellowish brown, abdomen brown; antennae brown; legs mainly yellow, femora brownish yellow; fore wing uniformly shaded; major setae on body and wings dark brown. With the character states of the genus: antennal segments III and IV with constricted apical neck (Fig. 7); head with ocellar setae III and po IV long (Fig. 16); mouth cone extending to fore coxae; pronotum with 3 pairs of anteromarginal setae, none elongate; discal area with about 12 to 15 setae; posterior margin with 3 pairs, median pair longest, posteroangular setae long. Metanotal sculpture weak medially. Tergite I with transverse reticulate sculpture, but III–VIII with no sculpture mesad of setal pair S1 and lines weak on lateral areas; IV and V each with about 8 discal setae laterally (Fig. 43); X with longitudinal split complete (Fig. 23).
Measurements (holotype female in microns). Body length 1700. Head, length 100; width across eyes 165; ocellar setae III 60; po setae IV 70. Pronotum, length 150; width 220; pm S1 setae 50; pa setae 85. Metanotum median setae length 80. Fore wing length 1000. Antennal segments III–VII length 60, 50, 40, 48, 25.
Male. Body pale with weak brown markings laterally on meso and metanotum, major setae dark; antennal segment I white, II weakly shaded, III–VII brown; similar to female in sculpture; sternites III–VII with large, transversely oval pore plate (Figs 28, 29).
Measurements (paratype male in microns). Body length 1250. Ocellar setae III 48; po setae IV 50. Pronotal pa setae 65.
Specimens examined. Holotype female, Hawaii, Volcano, from Psychotria hawaiiensis, 9.vii.2016 (LAM 6246).
Paratypes: 10 females, 4 males taken with holotype; Hawaii, Volcano, Kipuka Ki, 7 females, 3 males from Psychotria hawaiiensis, 12.vii.2016. Oahu, Puu Hapapa, 3 females from Psychotria fls, 29.vi.2016.
Non-paratypes: Maui, Haleakala, 8 females, 6 males from Santalum haleakalae fls, 25.vii.2016.
Comments. The tergal chaetotaxy of this species is quite similar to that of multispinus (Figs 42, 43), and the type series came from a site very close to the collecting site of that species. However, despite their poor condition, the head of the multispinus females from Kilauea are slightly darker than the pronotum, not paler as in robbiei. This species shares with williamsi the unusually large form of the sternal pore plates of males (Fig 29), but the body colour is considerably darker that in that species. Even the particularly sharply bicoloured non-paratype specimens listed from Santalum are much darker than any available specimens of williamsi, in particular the fore wings are dark and antennal segment III is brown, even in the palest of the available males.
