diagnosis
Diagnosis. - Males of C. ceylonica are closely related to the males of Cryptothele alluaudi Simon, 1893 as both share a similar tegular extension but can be separated from the latter species by the round tegulum (vs. oval in C. alluaudi) (compare Fig. 1 B with Marusik & Omelko 2012: figs 5 – 8). Females of C. ceylonica can be separated from females of C. alluaudi by the shorter septum (SE) (vs. longer in C. alluaudi) (compare Fig. 1 H with Marusik & Omelko 2012: figs 4). Females of C. ceylonica can be separated from females of C. collina Pocock, 1901 by the presence of lateral pockets of the epigynum (vs. anterior hood in C. collina (compare Figs 1 H with Sankaran & Joseph 2022: fig. 1 c).
