description: Frankliniella bambusae n. sp.
(Figs 1, 7, 15, 20, 25, 30, 37)
Female macroptera. Colour: Body yellow, except for body setae, abdominal segment X and distal part of abdominal segment IX brown (Figs 1, 30). Antennal segment I pale, II pale with suffused brown area apically, III pale with apical third brown, IV–V brown with base brownish yellow, VI–VIII brown (Fig. 7). Fore wings pale. Structure: Head about 1.25 times as wide as long with a prolongation anterior to the eyes between the antennae; compound eyes with five pigmented facets; three pairs of ocellar setae, pair III close to external margins of ocellar triangle; five pairs of postocular setae, pair IV longer than the others, pair I absent (Fig. 15). Antenna 8-segmented, segments III and IV with forked sense cone, pedicel on III simple. Pronotum about 1.28 times as wide as long without major lines of sculpture; one pair each of major anteromarginal and anteroangular setae, anteroangulars more than three times as long as anteromarginals, one pair of major posteromarginal setae and two pairs of posteroangular setae, pair I about 1.1 times as long as II (Fig. 20). Mesonotum with transverse lines of sculpture, one pair of campaniform sensilla anteriorly, no setae on discal area. Metanotum with two pairs of setae anteriorly, campaniform sensilla absent, transverse lines of sculpture on anterior half, longitudinal lines on posterior half and laterally (Fig. 25). Fore wings with two complete rows of setae; first vein with 17 setae, second vein with 13 setae; clavus with 5 marginal and 1 discal setae; fringe cilia wavy. Abdominal tergites IV–VIII with well-developed ctenidia laterally, VIII with posteromarginal comb of microtrichia complete and regular, IX with two pairs of campaniform sensilla and S2 pair of setae 1.2 times as long as S1 (Fig. 30). Sternites II with one discal seta, craspeda present on sternites II–VII, sternite III with a pair of circular pore plates (Fig. 37).
Measurements (Female holotype, in microns): Body length 1725. Head, length 100 width 125; Ocellar setae III 30; postocular setae IV 15. Pronotum, length 120, width 153; pronotal major setae, aa 48, am 13, pm 16, pa I 55, pa II 48. Fore wing length 625. Tergite IX, length 88, S1 setae 93, S2 setae 113. Antennal segments I–VIII length 20, 35, 38, 35, 33, 45, 9, 13.
Male. Unknown.
Material Examined. Holotype female. Brazil. São Paulo: São Paulo, Instituto Biológico, 9.ix.2003, on Bambusa gracilis (E.A.Miyasato & S.D.L.Imenes) (IB).
Paratype: one female collected with the holotype (CHNUFPI).
Comments. Eight species, including catharinensis and bambusae, are currently known to exhibit pore plates on sternite III in females. From all of those species, bambusae can be distinguished readily by the yellow coloured body. More details on these species are discussed under catharinensis. The yellow colour with brown terminal abdominal segments of bambusae, however, is similar to condei and graminis. Apart from the pore plates on sternite III, it can be distinguished from condei by the pale colour of the second antennal segment as well as the less elongated antennal segments III–V; from graminis it can be distinguished by the longer pronotal aa setae, which are more than three times as long as the discal setae. Other comparisons with condei are difficult to trace because the only known specimen is not adequately cleared; in common with graminis, however, the metanotum does not bear campaniform sensilla. As in frumenti, graminis and williamsi, recorded on Poaceae in Brazil, it has head projected anteriorly. This character state seem to be an adaptation to living on Poaceae, as other groups of Thripidae living on grasses, such as Plesiothrips (Mound et al. 2016) and Chirothrips -related species (Nakahara & Foottit 2012) also exhibit this trait.
Etymology. The species is named after the plant on which it was collected.
