Paraprocts bright orange, triangular and wide, curved anteriorly. Hammer large, transversely rounded, and covered by distinct dark granules, slightly elevated in lateral view; surrounded by a large yellowish, axe shape area. Aedeagus membranous, shape similar to H. violacea , but most of surface with a few visible ventral spinules ( Fig. 16 ). Type material: Holotype : 1♂ ( ICYZU ), China , Guangdong Province , Shaoguan City , Nanling National Forest Park , 840 m , 24°54'60" N , 113°2'3" E , 2021-IV-20 , leg. Zhao Meng-Yuan. Etymology: The species is named in honor of Miss. Zhao Meng-Yuan, the collector. Distribution: China ( Guangdong Province ).
