 slightly porrect; sternum truncate in front; hind coxa) widely 

 separated. Legs quite long and slender, no spines, but with many 

 hairs ; beneath on tibiae, metatarsi and tarsi are rows of serrated, 

 semi-clavate hairs, each arising from a pointed granule; these are 

 most evident on anterior legs. Abdomen slightly depressed, 

 about one and one-half times as long as broad, nearly truncate at 

 base. The epigynum shows two elliptical approximate marks be- 

 neath the surface, in each outer posterior corner is a black circular 

 cavity, between them are two smaller black dots from which lines 

 extend to the furrow.
