Mycterothrips bicolor sp. n. (Figs 1–5) Female macroptera. Body bicolored (Fig. 1); head, thorax and abdominal segment I yellow, abdominal segment II brown, segments III–X dark brown; antennae brown, with apex of segment III pale (Fig. 4); all legs yellow; fore wings light brown with base yellow, clavus yellow (Fig. 5); prominent body setae brown. Head wider than long, slightly rounded at cheeks; ocellar setae I present, setae III situated near anterior margin of posterior ocelli; postocular setae I the longest (Fig. 2). Antennae 8-segmented, segment I with two dorsal apical median setae, II with 3 microtrichial rows on dorsal surface and a mid-dorsal seta below CPS on dorsal surface, III and IV widest at middle and tapering in distal neck-like third, III–VI with some rows of microtrichia on dorsal and ventral surfaces, VIII slightly longer than VII (Fig. 4). Pronotum wider than long, dorsal surface smooth, with a few transverse striations on posterior ¼; one pair of anteromarginal setae longer than discal setae; two pairs of posteromarginal setae, setae I longer than II, inner posteroangular setae subequal to outer one (Fig. 2). Mesonotum with CPS present; median pair of setae situated near or on posterior margin. Metanotum with very weak reticulations, but with irregular longitudinal striations laterally, median pair of setae situated near anterior margin, CPS absent. Fore wing first vein with seven setae at base and two near apex, second vein with setal row complete; posterior fringe cilia slightly wavy; clavus with 5 marginal setae and one discal seta (Fig. 5). Abdominal tergites and laterotergites without ciliate microtrichia on lines of sculpture, but often with a few large irregular microtrichia on sculpture lines at least on segment VIII, posterior margin of tergites V–VII without microtrichia laterally; tergite II with 4 lateral marginal setae; tergites VI–VIII with S4 setae minute; tergite IX with both anterior and posterior pairs of CPS; tergite X split longitudinally in distal 1/3 (Fig. 3); sternites without discal seta; sternite VII with median pair of setae situated in front of posterior margin. Measurements (holotype female in microns). Body length 1390. Head, length 90; width across eyes 142. Ocellar setae III length 68. Pronotum, length 135; maximum width 162; posteroangular setae length, inner 70, outer 70. Metanotum median setae length 54. Fore wing length 778. Antennal segments III–VIII length 60, 53, 36, 45, 8, 17. Male. Unknown. Specimens examined. Holotype female: CHINA, Yunnan Province, Xuanwei City, Xize County, from Capsicum annuum, 3.x.2016 (Bo Kong), in collection of Yunnan Agricultural University, Kunming. Paratypes: 4 females collected with holotype, same locality and collector. Etymology. In reference to body bicolor. Comments. This species is very closely related to caudibrunneus in Taiwan, with the same coloration of abdomen and fore wing, ocellar setae I present, abdominal tergite II with four lateral marginal setae. However, it is distinguished by posterior margin of tergites V–VII without microtrichia laterally, metascutum with median pair of setae near anterior margin (Wang 1999, Masumoto and Okajima 2006). This species is also similar to consociatus, but differs in bicoloured body colour and fore wing with base pale.
