Other external differences among the three species are stated under  T. prunifolivora. The male genitalia of  T. lacrimiformisare diagnosed by the valva convex at middle of the ventral margin, the ovate anellus lobe with a strongly hooked apical bristle and the triangular process of juxta. The female genitalia are differentiated from its allies by the medially membranous sternum VIII with small teardrop-shaped medial sclerotization and the very slender ductus bursae. The signum is somewhat similar to that of  T. umbrosidorsa. However, the signum of  T. lacrimiformisis situated near the entrance of ductus bursae and concave laterally, whereas it is placed at middle of the corpus bursae and the lateral margins are more straight in the latter species.   Description.Adult ( Fig. 7G). Wingspan 6.0−9.0 mm. Head cream, sometimes suffused with light ochre. Labial palpus ochreous white, sprinkled with fuscous; segment III slightly shorter than II. Antenna with scape cream; flagellum dark fuscous except base of dorsal surface cream, male cilia approximately 3 times as long as diameter. Thorax cream. Tegula cream, anterior margin usually fuscous. Forewing cream, anterior edge of costa black, apical spot elliptical, markings dark fuscous: an oblique costal streak from distal 1/3 toward apical spot; beyond this, a triangular costal patch before apical spot, usually interrupted by creamy scales medially; tornus with an irregular spot, sometimes enlarged, its anterior margin extending toward apex as a slender longitudinal streak, often interrupted by creamy scales, usually confluent with costal streak and reaching apical spot; costal fringe cream with subterminal and terminal fuscous bands; fringe on termen creamy white, before apex with subterminal and terminal fuscous bands; fringe on dorsum cream and light grey mixed. Hindwing fuscous, fringe light grey. Legs light ochre; fore coxa sprinkled with fuscous; fore femur, tibia and tarsus dark fuscous on outer surface; mid and hind tibiae strongly sprinkled with fuscous; mid and hind tarsi with first tarsomere dark fuscous at base and beyond middle, remaining tarsomeres dark fuscous except apex.  Male sternum VIII( Fig. 23N). 1/6 length of abdomen, posterior margin deeply concave in triangle shape.  Male genitalia( Fig. 31B). Uncus rounded, sparsely setose along lateral margins. Gnathos hook moderately long, simple. Tegumen approximately 5 times as long as uncus, anterior margin deeply concave. Valva with ventral margin gradually broadening from base to middle, then narrowing to distal 1/3, broadening again to rounded apex. Anellus lobe ovate, slightly shorter than 1/3 length of valva; apical bristle robust, approximately 1/2 length of anellus lobe, strongly hooked. Juxta with a triangular process. Vinculum slender, nearly straight posteriorly. Saccus very broad, subtriangular, as long as tegumen pedunculus.Aedeagus with basal half slightly dilated, slender distally, sharply pointed at apex.  Female genitalia( Fig. 48E). Papillae anales moderately sclerotized. Apophyses anteriores slightly shorter than apophyses posteriores. Tergum VIII membranous. Sternum VIII membranous medially, anterior margin strongly produced in U-shape; medial sclerotization small, teardrop-shaped, not extending to ductus bursae. Ostium bursae very small. Ductus bursae very slender, slightly broadened at base, with a broad colliculum near base, ductus seminalis arising from posterior 1/4. Corpus bursae ovate, 2/3 or 1/2 length of ductus bursae; signum situated near entrance of ductus bursae, somewhat hastate: its posterior margin broadly convex, widest at posterior 1/4, lateral margins concave, narrowed toward anterior apex.   Distribution. China( Hainan, Sichuan, Xizang).   Etymology.The species name is derived from Latin,  lacrimiformis(tear-shaped), referring to the teardrop-shaped sclerotization on the sternum VIII of female. 2016-01-20 Kaijian Teng & Xia Bai & Mengting Chen 540 19.08 Hongkan 764 109.5 Yinggeling 31 32 1 1 Hainan holotype 2013-05-08 Yinghui Sun & Wei Guan & Tengteng Liu China Changjiang County 245 19.09 Bawangling 763 109.11 31 32 2 2 Hainan paratype 2014-04-30 Tengteng Liu & Wei Guan & Xuemei Hu China Ledong County 40 18.7 Jianfeng Town 765 108.79 Tropical Arboretum 31 32 1 1 Hainan paratype 2015-05-20 Peixin Cong & Wei Guan & Sha Hu China 742 18.88 Wuzhishan Nature Reserves 764 109.65 31 32 2 2 Hainan paratype 2015-06-15 Peixin Cong & Wei Guan & Sha Hu China 508 19.08 Yinggeling 764 109.5 Hongkan 31 32 1 1 Hainan paratype 2015-07-06 Qingyun Wang & Suran Li & Mengting Chen China 766 18.88 Wuzhishan City 764 109.67 Shuiman Town 31 32 3 3 Hainan paratype 2015-07-10 Qingyun Wang & Suran Li & Mengting Chen China 302 18.7 Qixianling National Forest 765 109.68 31 32 2 2 Hainan paratype 2016-02-27 Qingyun Wang & Suran Li & Shengnan Zhao China 766 18.88 Wuzhishan City 764 109.67 Shuiman Town 31 32 1 1 Hainan paratype 2016-11-02 Xia Bai & Shuonan Qian & Wanding Qi China 738 18.9 Wuzhishan Nature Reserves 764 109.67 31 32 1 1 Hainan paratype 2017-05-12 Xiaofei Yang China 700 19.05 Yinggeling 764 109.56 Yinggezui 31 32 1 1 Hainan paratype 2017-08-05 Xia Bai & Ping Liu & Shuai Yu China 732 18.91 Mt.
