Differential diagnosis
The new species resembles Acroterius longidentatus gen. et sp. nov. ( Fig. 29A–C View Fig ) in having a similar circular posterior projection of the anterior wall of the epigynal plate in the epigyne ( Fig. 36A–C View Fig ); it can be distinguished by the anterior wall of the oval epigynal plate margin ( Fig. 36A–B View Fig ), but semicircular in A. longidentatus gen. et sp. nov. ( Fig. 29A–B View Fig ). In dorsal view, parmula with wave-like margin and almost four times as long as median septum ( Fig. 36D View Fig ), but tongue-shaped and as long as median septum in A. longidentatus gen. et sp. nov. ( Fig. 29D View Fig ). The spermathecae are hook-shaped ( Fig. 36D View Fig ), but C-shaped in A. longidentatus gen. et sp. nov. ( Fig. 29D View Fig ).
Etymology
The species name comes from the Latin adjective ‘ ovatus ’, meaning ‘oval’ and referring to the oval anterior wall of the epigynal plate margin of the epigyne.
