The species name comes from the Latin adjective “ acutalis ” meaning “pointed” referring to the pointed end of pit hook (distal suprategular apophysis) in male palp. Types.

The new species resembles to the type species Herbiphantes cericeus ( Saito, 1934 ) in having the similar long tibia of male palp and the broad epigynal scape ( Figs 3 A–D, 4A–D, 5A, B, 6A–C, 7A, B; Tanasevitch, 1992 , fig. 1e, 2i ), but can be distinguished by: the pit hook hook–shaped with pointed end in new species ( Figs 3A, B , 4A, B , 5A, B ), whereas slightly curved in H. cericeus ( Tanasevitch, 1992 , fig. 1e). The distal arm of paracymbium longer than wide in new species ( Figs 3B , 4B , 5B ), whereas wider than long in H. cericeus ( Tanasevitch, 1992 , fig. 1e). Epigynum can be distinguished by the posterior median plate triangular in new species ( Figs. 6 A–C, 7A, B), whereas not triangular in H. cericeus ( Tanasevitch, 1992 , fig. 2i ).
