Compared to other species in this group,  T. candidipalpausually has a somewhat larger forewing with lighter ground color. The white labial palpus and the distally narrowed valva are diagnostic characters for this species.   Description.Adult ( Fig. 8H). Wingspan 8.5−12.0 mm. Head white. Labial palpus white and slender, segment III as long as II. Antenna with scape white, flagellum brown and dorsal surface strongly mixed with white, male cilia shorter than diameter. Thorax white, often with a very slender, light brown median line. Tegula white. Forewing ground color white to dirty-white, often slightly mixed with cream in distal half, apical spot large and round, its anterior and posterior margins bordered with white, the white scales sometimes forming two small spots, markings dark brown: a broad band along costa from base to distal 1/4, curved downward and narrowed beyond middle; a costal streak from between distal 1/3 and 1/4, gradually narrowed and running obliquely toward apical spot; beyond this a triangular costal patch before apical spot, separated from former streak by a narrow white streak; a short streak running from tornus to apical spot, confluent with costal streak before apical spot; a slender streak from basal 1/3 of dorsum, often interrupted by white scales on dorsum, running obliquely to basal 2/3 across wing, almost reaching end of costal band anteriorly; a slender streak from distal 1/4 of dorsum, running along fold toward base, then curved opposite direction at distal 1/3, confluent with costal and tornal streaks near apical spot; fringe on costa and termen dark fuscous with base white, somewhat metallic. Hindwing dark fuscous except subapex white and apex black; fringe fuscous, apical area white with a terminal dark fuscous band. Legs white; fore femur, tibia and tarsus dark fuscous on outer surface; mid and hind tibiae with an oblique black streak beyond middle on outer surface, respectively; mid tarsus with first tarsomere shortly fuscous at middle; hind tarsus with first tarsomere broadly fuscous at middle, second tarsomere fuscous in basal half, remaining tarsomeres strongly mixed with fuscous overall.  Male sternum VIII( Fig. 24C). Approximately 1/6 length of abdomen, subtriangular, with lateral margins broadly convex, slightly concave before posterior apex; posterior apex rounded.  Male genitalia( Fig. 32E). Uncus rounded, with long setae along apical margin. Gnathos hook long and simple. Tegumen approximately 4 times as long as uncus. Valva straight, with base narrow, then slightly broadened in basal 1/2, gradually narrowed in distal 1/2, rounded at apex. Anellus lobe clavate, basal 1/2 strikingly constricted, distal 1/2 bulbous; apical bristle 1/4 to 1/3 length of valva. Juxta slightly convex medially, with long sparse setae. Vinculum simple. Saccus elongate subtriangular, sometimes broader than width of valva. Aedeagus with basal 2/5 dilated, uniformly elongate distally, apex truncate or weakly pointed.  Female genitalia( Fig. 50A). Papillae anales moderately sclerotized. Apophyses anteriores 3/5 length of apophyses posteriores. Tergum VIII broadly concave on anterior and posterior margins. Sternum VIII longer than tergum VIII, posterior 1/2 with an oblong sclerotization above ostium bursae, anterior margin strongly elongated. Ostium bursae opening at middle of sternum VIII. Ductus bursae short, with base narrow, abruptly broadened at inception of ductus seminalis, then gradually broadening toward corpus bursae. Corpus bursae elongate elliptical; signum small and rounded, situated at posterior 1/4 or 1/3, bulged inward, with minute denticles.   Distribution. China( Gansu, Hebei, Hubei, Liaoning, Tianjin, Zhejiang), Korea.   Etymology.The species name is derived from Latin, candidus(white) and palpi, referring to the white palpi.   Remarks.This species was reported from Koreafor the first time by Koo et al. (2020)as  Thiotrichasp.Also, it is  Thiotrichasp. 5in Lee et al. (2021)for the phylogenetic study of Thiotrichinae. The genetic sequences are available from GenBank. 2011-07-28 Houhun Li & Yanpeng Cai Xinglong County 800 40.61 Shuangyuanfeng 697 117.45 Mt.
