( Figs 12 , 48–55 ) Female (macroptera) . Distended body length: 1.9–2.1mm . Bicolored species ( Fig. 12 ). Head, thorax and tube brown; abdominal segment I yellow, with weakly shaded with brown laterally; segments II – VIII largely yellowish, scarcely shaded with pale brown, at least much paler than head and thorax, segments III – VIII each with a median indistinct marking along antecostal suture; segment IX pale brown, but yellowish at anterior half. Fore and mid coxae brown, hind coxae pale brown; fore femora brown with apices yellowish, mid and hind femora yellow; fore tibiae brownish yellow, mid and hind tibiae yellow; tarsi yellow. Fore wings shaded with pale brown, but paler at base and apex. Major body setae pale. Head about 1.6 times as long as wide ( Fig. 48 ), 1.63 times in holotype , widest across cheeks, dorsal surface almost smooth. Cheeks weakly rounded, weakly serrate. Postocular setae shorter than eyes, expanded at apex, 93µm apart from each other, 11–12µm apart from eyes in holotype . Eyes about one-third as long as head, 0.35 times in holotype . Ocelli well developed; posterior pair 21µm apart from each other in holotype . Antennae about 1.5 times as long as head ( Fig. 52 ), 1.54 times in holotype ; segment VIII weakly constricted basally ( Fig. 54 ), narrowly fused to segment VII , 0.67 times as long as VII ; segments III shorter than IV ( Fig. 55 ), longer than segment VII ; segments III and IV with two (1+1) and four (2+2 +1 ) sense cones respectively, sense cones on segment III slender. Maxillary stylets reaching postocular setae, about 1/6 of head width or a little wider, 23µm apart from each other in holotype ; maxillary bridge weak. Pronotum about 0.62 times as long as head, 1.33 times as wide as long in holotype , almost smooth; four pairs of prominent setae expanded; aa and ml subequal in length, epim the longest. Notopleural sutures complete. Prospinasternum very large, widely fan-shaped, about 60µm wide; mesopresternum reduced, divided into two lateral triangle plates; basantra a little wider than long ( Fig. 49 ). Metanotum sculptured medially with longitudinal reticulation ( Fig. 50 ); median pair of setae weak, short and acute, less than 20µm in length, 24µm apart from each other, about 50µm apart from anterior margin. Fore wing with 4–5 duplicated cilia, 5 in holotype ; three sub-basal setae expanded. Pelta trapezoid ( Fig. 51 ), sculptured weakly, almost as long as wide. Tergite IX S1 setae abdominal expanded, shorter than tube, S2 pointed, a little longer than tube. Tube 0.45 times as long as head ( Fig. 55 ), about 1.6 times as long as wide. Terminal setae about 2.4 times as long as tube . FIGURES 48–55 . Karnyothrips affinis sp. n. , female (mac.). (48) Head; (49) prosternum & mesopresternum; (50) metanotum; (51) pelta; (52) antenna; (53) fore tibia & tarsus; (54) metathoracic sternopleural region; (55) tube. Measurements ( holotype macropterous female in µm). Body length about 2100 (distended). Head length 212, from anterior margin of eyes 195, width across eyes 128, maximum width across cheeks 130, minimum width across base 107; eyes length 74; diameter of posterior ocelli 11–16; postocular setae about 40. Maxillary bridge width 29. Antenna total length 326, segments III–VIII length (width) as follows: 45 (26), 50 (28), 42 (24), 39 (22), 42 (18), 28 (11). Pronotum length 132, width 175. Setae on prothorax: aa 30–35, ml?30, pa?35, epim 50–53. Fore wing length 770. Sub-basal wing setae: S1 33 , S2 41 , S3 48 . Pelta length 78, width 78. Tergite IX setae: S1 65, S2 100–104. Tube length 95, maximum width 59; terminal setae 225. Male . Unknown Type material . Holotype : macropterous female, Indonesia , Bali , Tabanan , Muncak Sari , Pura Luhur , 755m alt., habitat uncertain, 3.ix.2006 , SO . Paratypes : Indonesia , Bali , 2 females (mac.), collected together with holotype . Comments . This species is described based on three macropterous females collected from Bali , Indonesia . It has the body bicolored brown and brownish yellow, antennal segments III and IV with two (1+1) and four (2+2 +1 ) sense cones respectively and tergite IX S1 setae expanded at apex. It may be most similar to K. macrommatus sp. n. from Sulawesi , Indonesia . However, it can easily be distinguished by the following features (in parentheses are the features of macrommatus ); metathorax largely brown (largely yellow); eyes smaller, at least shorter than 0.4 times as long as head (about 0.4 times); maxillary stylets closer together, about one-sixth of head width in female (about one-fourth of head width); fore wing with 4–5 duplicated cilia (7–9); tube shorter than 0.5 times as long as head (0.55 times); terminal setae longer than 2.0 times as long as tube (shorter than 1.5 times as long as tube).
