Stenchaetothrips bambusicola Mound, 2011
(Figs 22–25)
Female macroptera. Body brown; legs pale; antennal segment I brown, II pale on apical half, III yellow, IV–VI slightly shaded in apical half, VII–VIII light brown; fore wing uniformly shaded, paler at fourth basal. Head about as long as wide; ocellar setae II much longer than setae III; post-ocular setae I and III, V and VI long, II and IV minute (Fig. 22). Pronotum with 22–24 discal setae, with weak, widely spaced transverse striations; 2 pairs of long postero-angular setae, 3 pairs of postero-marginal setae (Fig. 22). Mesonotum with anterior campaniform sensilla, median setae arising in middle. Metanotum with closely spaced striations, campaniform sensilla present, median setae arising behind anterior margin (Fig. 23). Meso- and metafurca each without a spinula;
Abdominal tergites V–VIII with paired ctenidia; tergites I–VII posterior margin laterally with a few weakly dentate microtrichia, extending medially on tergite VII; tergite VIII with complete comb of slender microtrichia (Fig. 25); submedian and median setae on VIII sub-equal and short, not extending beyond posterior margin; two pairs of campaniform sensilla on IX. Sternites smooth, posterior margins without dentate craspedum, with 3 pairs of posteromarginal setae; median posteromarginal setae on segment VII arising in front of posterior margin; V–VI with a small transverse pore plate medially (Fig. 24).
Material studied. Malaysia, Terengganu, Kerteh, 1 female from Schizostachyum zollongeri (Poaceae), 4.iii.2014 (Syarifah, Z.), in CISUKM.
Comments. Previously known only from northern Australia, near Darwin, this is the first record outside the continent of Australia (Mound 2011). It can be identified by the presence in females of a small transverse pore plate on each of abdominal sternites V–VI. The body is uniformly brown and the metanotum bears a pair of campaniform sensilla. Mound (2011) described bambusicola based on samples from Bambusa arnhemica, and the species was compared with information given by Bhatti (1982) concerning two closely similar species, divisae and bambusae .
