Both males and females are similar to S. cambridgei in their body size and proportion, shape of the atrium and folds of epigynal plate and by the single long and pointed RTA on male palp. S. spiralis can be distinguished by its darker body colour, which is dark-brown rather than orange; by females having a wider atrium ( Fig. 46C ) and spiral copulatory ducts vertically positioned ( Fig. 45D ); and by the male palp bearing an embolus coiled at its basis and a cymbium longer than wide directed retro laterally ( Fig. 46C ). Description . Female (AMS KS.114827): Cephalic area prominent (not as much as in S. altifrons but higher than in S. cambridgei ), eyes arranged in a strongly recurved anterior row and in a straight posterior one; prosoma, opisthosoma and legs uniformly dark-brown (almost black), covered by many hyaline or whitish setae ( Fig. 45A ). Spermathecae long, sclerotized, coiled (2 coils) and bearing a pair of glandular-heads pointing sideways ( Fig. 45D ). Figure 46 . Stephanopis spiralis sp. nov. , male (AMS KS.91528).
