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

The specific name comes from the first name of the collector; noun.
