Adult female, slide-mounted, 0.9-1.1 mm long, usually wider than long; prosoma strongly reniform and heavily sclerotised at maturity; postsoma less sclerotised than prosoma or membranous, often retracted between prosomal lobes. Median lobes usually larger than 2nd and 3rd lobes; 4th lobes represented by small to moderate-sized points. Plates all fringed. Thoracic tubercles small or absent. Perivulvar pores present in 2 groups, usually 1 or 2 at each postero-lateral position; prevulvar scleroses and apophyses absent.
