Differential diagnosis
Male of Spinirta hongyui Wang, Lu & Z.S. Zhang sp. nov. resembles S. simianshan Wang, Lu & Z.S. Zhang sp. nov. in having the similar tibial apophyses and somewhat quadrangular embolar apophysis (Figs 4A–B, 5F–G vs Figs 10A–B, 11F–G) but can be distinguished by the embolus tip with blunt end in S. hongyui (Figs 4A, 5F), vs retrolateral margin of embolus serrated in S. simianshan (Figs 10A, 11F); ventral margin of retrolateral tibial apophysis wavy in S. hongyui (Figs 4A, 5F), vs smooth, rounded in S. simianshan (Figs 10A, 11F). Female can be distinguished by the atrium septum indistinct in S. hongyui (Figs 4A, 5F), vs distinct, dividing atrium into two halves in S. simianshan (Figs 10A, 11F); copulatory opening present laterally in S. hongyui (Figs 4C, 5C), vs present posteriorly in S. simianshan (Figs 10C, 11C); accessory glands present in S. hongyui (Figs 4D, 5D), vs absent in S. simianshan (Figs 10D, 11D).
Etymology
