Differential diagnosis
Male of Spinirta liuae Wang, Lu & Z.S. Zhang sp. nov. resembles S. hongyui sp. nov. in having the similar embolus ( Figs 6A–B View Fig , 7E–G View Fig vs Figs 4A–B View Fig , 5E–G View Fig ) but can be distinguished by the embolus shorter than embolar apophysis in S. liuae ( Figs 6A–B View Fig , 7F–G View Fig ), vs as long as embolar apophysis in S. hongyui ( Figs 4A–B View Fig , 5F–G View Fig ); embolar apophysis thumb-shaped in S. liuae ( Figs 6A–B View Fig , 7F–G View Fig ), vs quadrangular in S. hongyui ( Figs 4A–B View Fig , 5F–G View Fig ); ventral tibial apophysis large, with rounded tip in ventral view in S. liuae ( Figs 6A View Fig , 7F View Fig ), vs triangular in S. hongyui ( Figs 4A View Fig , 5F View Fig ); retrolateral tibial apophysis ventrally hookshaped projection in S. liuae ( Figs 6B View Fig , 7G View Fig ), vs ventrally absent any projection in S. hongyui ( Figs 4B View Fig , 5G View Fig ). Female can be distinguished from S. hongyui by the spermathecae present mid dorsally, separated by a distance two times longer than their diameter in S. liuae ( Figs 6D View Fig , 7D View Fig ), vs present at posterior end, separated by a distance almost equal to their diameter in S. hongyui ( Figs 4D View Fig , 5D View Fig ); accessory glands quite visible in S. liuae ( Figs 6D View Fig , 7D View Fig ), vs slightly visible in S. hongyui ( Figs 4D View Fig , 5D View Fig ).
Etymology
The specific name comes from the family name of the collector Ms Jia Liu; noun.
