Neurisothrips tsuda View in CoL sp. n.

( Figs 8 View FIGURES 1–14 , 17 View FIGURES 15–23 , 35 View FIGURES 33–38 , 45 View FIGURES 39–49 )

Female. Body and antennae dark brown, legs light brown with mid and hind tibiae paler distally; tarsi brownish yellow; fore wing pale to weakly shaded; major setae dark. With the character states of the genus: antennal segment III with apex weakly constricted ( Fig. 8 View FIGURES 1–14 ); head with ocellar setae III and po IV long, po setae pair I present ( Fig. 17 View FIGURES 15–23 ); mouth cone extending to fore coxae. Pronotal anterior margin with 3 or 4 pairs of setae including anteroangulars; discal area transversely reticulate, with at least 12 setae; posterior margin with 3 pairs, median pair longer than discal setae, posteroangular setae long. Metanotum reticulate medially. Fore wing first vein with about 21 setae, second vein with about 16 setae. Tergite I with transverse reticulate sculpture; III–VIII with no sculpture mesad of setal pair S1 but with transverse reticulation on lateral areas ( Fig. 45 View FIGURES 39–49 ); IV and V each with 6 to 8 discal setae laterally; X with longitudinal split usually incomplete.

Measurements (holotype female in microns). Body length 1700. Head, length 125; width across eyes 160; ocellar setae III 70; po setae IV 70. Pronotum, length 130; width 210; pm S1 setae 55; pa setae 105. Metanotum median setae length 70. Fore wing length 950. Antennal segments III–VII length 60, 50, 40, 50, 25.

Male. Similar in colour and structure to female; sternites III–VII each with transverse pore plate.

Measurements (paratype male in microns). Body length 1200. Ocellar setae III 55; po setae IV 40. Pronotal pa setae 90.

Specimens examined. Holotype female, Maui, Haleakala (20° 42’N, - 156° 15’W), on Styphelia lvs, 25.vii.2016 (LAM 6292).

Paratypes: 5 females, 7 males taken with holotype; same locality, 9 females, 6 males from Geranium fls, 25.vi.2016; same locality and date, 4 females, 5 males from flowers of Dubautia , Vaccinium and dead branch of Coprosma . Hawaii, Mauna Loa Trail, 11 females, 7 males from Styphelia lvs, 22.vii.2016.

Comments. This species is closely similar to multispinus , with which it appears to share a similar pronotal chaetotaxy, although the pronotal sculpture of the multispinus type specimens appears to be weaker. The species are distinguished here by the single tergal character state indicated in the key above.
