Diagnosis
. Males of
S. flagellata
sp. nov.
are almost indistinguishable from those of
S. altifrons
and
S. nigra
somatically. All three species possess a high cephalic prominence (
Fig. 27B
), flattened prosoma and obovate opisthosoma with stout setiferous tubercles on the rear (
Fig. 27A
). However,
S. flagellata
sp. nov.
can be easily distinguished from these species by its remarkable palpi: a larger PrsP, long whip-like embolus (coiled at its terminal portion and resting behind the tegulum) and a RTAvbr acute and long, having thrice the size of the RTA (
Fig. 27C and D
).
