( Figs 3 , 31 ) Female . Body and legs yellow with pale ocellar pigment, fore wings pale to weakly shaded, major setae pale particularly on head; antennal segment I as pale as head, II light brown at apex, III–VII brown but III paler on basal half. With the character states of the genus: antennal segments III and IV scarcely constricted at apex ( Fig. 3 ); head with ocellar setae III and po IV short, po setae pair I present; mouth cone extending to fore coxae; pronotum with 2 pairs of anteromarginal setae and one pair of anteroangular setae; discal area with about 20 setae; posterior margin with 3 pairs, median pair less than 1.5 times as long as submedian pairs, posteroangular setae unusually short. Tergites III–VIII with sculpture lines lateral to setal pair S1; IV and V each with 5 to 7 discal setae laterally; X with longitudinal split not fully complete. Sternites with 10–12 discal setae arranged irregularly ( Fig. 31 ), not in a transverse row. Measurements ( holotype female in microns). Body length 980. Head, length 90; width across eyes 125; ocellar setae III 25; po setae IV 23. Pronotum, length 110; width 140; pa setae 35. Metanotum median setae length 30. Fore wing length 650. Antennal segments III–VII length 38, 35, 30, 40, 20. Male . Similar in colour and chaetotaxy to female; 2 pairs of setae on tergite IX arranged in almost straight transverse line; sternites with 1–2 discal setae present medially, but pore plates not visible because specimen not cleared. Measurements ( paratype male in microns). Body length 830. Pronotal pa setae 35. Specimens examined . Holotype female, Molokai , Waikolu Valley ( 21° 07’N , - 156° 55’W ), from leaves of Raillardia molokaiensis (= Dubautia ), 10.x.1943 (N.L.H.Krauss). Paratypes : 5 females , 1 male taken with holotype . Comments . The holotype is the female mounted dorsal side uppermost on a slide with a paratype female that is mounted ventral side uppermost ( Fig. 31 ). The pale body colour and pale ocellar pigment are similar to the condition found in dubautiae , a species that was described from a plant in the same genus. However, among the species of Neurisothrips the presence of sternal discal setae is shared only with bidens described above.
