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 ). Figure 27 . Stephanopis flagellata sp. nov. , male (AMS KS.128001). (A) dorsal habitus; (B) front; (C) ventral view of the left palp; (D) left palp, retro lateral view. Description . Male (AMS KS.128001): Anterior eye row strongly recurved ( Fig. 27A ) and posterior row slightly procurved ( Fig. 27B ); prosoma predominantly dark-yellow with brown tinges on the sides of cephalic portion ( Fig. 27A ). Posterior legs (III and IV) predominantly yellowish as in the prosoma; anterior legs (I and II) entirely brown on the femora and gradually fading into yellow along the tibiae and metatarsi, with sparse dark spots. Opisthosoma dark-yellow, with concave anterior border and clusters of 3 to 5 long setae on the posterior setiferous tubercles ( Fig. 27A ).
