( Figs 53 A–E, 54A–D, 55A–B) in having a thin embolus with a reduced embolic apophysis and lateral lobes fused, with almost horizontal margins anteriorly, but can be separated by: 1. Male palp with dRTA narrow and dorsally digitiform (wide, bulging in S. tumefacta ); 2. Female vulva with glandular appendages short (long in S. tumefacta ), posterior parts of spermathecae distinctly swollen (slightly swollen in S. tumefacta ). Description.
