Etymology. The species name is after Tingyu Fang (in Chinese, Ẇ廷玉), one of the discoverers of this new species.
Description of male.
Head. ( Fig. 1A–B, D View FIGURE 1 ). Mostly ochraceous after death. Eyes blackish brown, with dense golden hair along posterior margin. Black markings along frontoclypeal suture and median black spot enclosing ocelli. Lorum with paired black markings. Anteclypeus with black patches laterally. Postclypeus prominent with blackish brown fasciae along submedian parts of transverse grooves, transverse cross-section rounded. Rostrum with apex blackish, extending to hind coxae.
Thorax. ( Figs 1A View FIGURE 1 , 2A–F View FIGURE 2 ). Pronotum longer than head, almost ochraceous after death; inner area with paired of central longitudinal blackish marking, with anterior ends widened laterad, and with blackish symmetrical markings widespread over inner area; pronotal collar symmetrically with paired black spots on posterolateral area, and lateral part of pronotal collar not dentate. Mesonotum fundamentally ochraceous after death with following blackish markings: medial longitudinal arrow-shaped marking reaching anterior margin of cruciform elevation, paired inwardly curved markings along each parapsidal suture, paired markings along lateral sigilla, which and the latter are sometimes connected with paired markings on scutal depression sometimes ( Fig. 2A, C, E View FIGURE 2 ).
Legs. ( Fig. 1C View FIGURE 1 ). Ochraceous with brown patches. Fore femora swollen and equipped with three blackish brown spines beneath: primary spine pointed and oblique to femur; secondary spine broader with acute tip, erect; subapical spine short.
Wings. ( Figs 1A–B View FIGURE 1 , 2A–F View FIGURE 2 ). Hyaline. Forewing with distinct fuscous spots on radial and radiomedial crossveins, marginal series of minute fuscous spots present on apex of longitudinal veins of apical cells; obscure fuscous spot present on the medial crossvein and cubitus anterior vein ( Figs 1A–B View FIGURE 1 , 2A, C–F View FIGURE 2 ), which may vanish in some specimens ( Fig. 2B View FIGURE 2 ). Hindwing has no markings.
Abdomen. ( Figs 1A–B, E–F View FIGURE 1 , 2A–F View FIGURE 2 ). Cylindrical balloon, noticeably longer than head and thorax together. Abdominal tergites II–VI brown with blackish markings on posterior margins of tergites, abdominal tergites VII, VIII and pygofer in dorsal view blackish. Abdominal sternites brown, without tubercles. Timbal cover scale-like, ochraceous; timbal mostly concealed by timbal cover. Opercula widely separated and slightly longer than wide, not extending beyond posterior margin of abdominal sternite II.
Genitalia. ( Figs 1G–I View FIGURE 1 , 3A–C View FIGURE 3 ). Pygofer elliptical in ventral view, ochraceous with apex blackish brown ( Fig. 1G–I View FIGURE 1 ). Dorsal beak pointed, lower than the height of anal styles in lateral view ( Fig. 1G–I View FIGURE 1 ). Distal shoulders broadly triangular, distally extended into pointed lobe ( Fig. 1H–I View FIGURE 1 ). Basal lobes large, oblique outwardly, substantially confluent with pygofer margin in ventral view ( Fig. 1G–I View FIGURE 1 ). Uncus with middle groove to hold aedeagus ( Figs 1G View FIGURE 1 , 3A View FIGURE 3 ); in addition to the paired uncal lobes which extrude ventrally and curved inwardly, the uncus bears distinct lateral lobe on each side ( Fig. 1H, I View FIGURE 1 ). Aedeagus somewhat S-shaped, long and thin, with apex extending the base of paired uncal lobes ( Fig. 1G View FIGURE 1 ), slightly broader at base and gradually narrowed apically in lateral view ( Fig. 3C View FIGURE 3 ) and truncate apically in ventral view ( Fig. 3B View FIGURE 3 ).
Female. ( Figs 2E–F View FIGURE 2 , 4A–E View FIGURE 4 ). Opercula small, posterior margin not reaching abdominal sternite II. Abdominal tergite IX blackish in dorsal view and ochraceous in ventral view; ovipositor sheath black, protruding beyond apex of segment IX, posterior margin of sternite VII incised at middle. Other characteristics similar to male.
Exuvium. ( Fig. 5A–B View FIGURE 5 ). Generally light ochraceous, curved in lateral view. Head, pronotum, and mesonotum without fascia. Abdomen ochraceous with light ochraceous fasciae on posterior margins of tergites.
Ecology. A. fangtingyui sp. n. lives in subtropical forests (~ 200–1000 m) in South China. Males of this species prefer to sing and sit on the branches and trunks of Cyclobalanopsis glauca in the afternoon from mid-June to the end of August ( Fig. 5C–D View FIGURE 5 ).
Distribution. China (Fujian, Jiangxi, Guangdong, and Guangxi).
Remarks. Adults of A. fangtingyui sp. n. are dominantly green with the abdomen brown when alive ( Fig. 6B–D View FIGURE 6 ). The colors of head, thorax and opercula would change to ochraceous in dry specimens ( Figs 2B–D, F View FIGURE 2 , 6A View FIGURE 6 ). A. fangtingyui sp. n. exhibits morphological variations, including the absence/presence of fuscous spot on medial crossvein, the absence/presence of the minute fuscous spot on the apex of the cubitus anterior vein of the forewing. In addition, the paired markings along the lateral sigilla in some individuals are connected with the paired spots on the scutal depression ( Fig. 2A, C, E View FIGURE 2 ). Merely one exuvium of the new species was photographed in the field by one of the discovers (Tingyu Fang) of A. fangtingyui sp. n., and no material of exuvium is available for detailed observation for this study. The morphology of the exuvium is in need to be investigated in the future. This new species occurred sympatrically and simultaneously with Macrosemia pieli (Kato, 1938) , Pomponia linearis (Walker, 1850) , Meimuna opalifera (Walker, 1850) , Purana gigas (Kato, 1930) and Maua squeala Wang, Duffels & Wei, 2021 in the forests.
