Genera of the Scirtothrips genus-group (Thysanoptera, Thripidae) with a new species of Siamothrips from Malaysia Author Mound, L. A. text Zootaxa 2015 4021 2 387 394 journal article 10.11646/zootaxa.4021.2.9 20dc9fa0-91f0-4bc3-8b2d-5ead61ffd0c2 1175-5326 239146 C811FF22-C410-40CA-BFA8-CA3918E5933B Cercyothrips Morgan, 1925 ( Figs 1–2 ) The two species described in this genus were both based on single females, the type-species from Puerto Rico and the other from Trinidad . However, Mound and Marullo (1996) reported a series of both sexes from southern Brazil that apparently represent the type species, and the figures given here are of one of these females from Brazil . This genus shares with Kenyattathrips and Scirtidothrips the unusual character state of having the sternal posteromarginal setae arising in front of the margins ( Fig. 2 ). However, the chaetotaxy in the former genus is very different as indicated below. Antennal segments VII and VIII are far more slender than those in the second genus, and the metanotum has transverse sculpture lines ( Fig. 1 ) that are similar to those found in Ajothrips .
