♂
(IFS_SAL_254), same locality and collection data as in

.
Etymology.
The species is named after Rosalind Senior, the heroine of the play As You Like It by William Shakespeare. Generally noted for her resilience, quick wit, and beauty.
Diagnosis.
The species is closely related to
S. hortonensis
sp. nov.
in the palpal structure. However, it is distinguished from this and other
Sri Lanka
species of the genus by the stout, compact embolus, presence of well-developed MA, absence of PL (
Figs 7D
,
8B
) and well-developed apical tibial apophyses (
