Diagnosis.

Body fusiform, white translucency or yellow. Gnathosoma curved obliquely downward, dorsal genual setae (d) bend forming obtuse angle at middle. Prodorsal shield with frontal lobe present; all lines bold and connected with transverse lines forming network; scapular tubercles and setae absent. Coxisternal plates sculptured with lines, prosternal apodeme present, coxigenital annuli 4. Legs segments normal, legs II with genual setae ( l’’) absent, tarsal empodium entire, 6-rayed, tarsal solenidion knobbed. Dorsal opisthosoma with shallow median furrow, dorsal annuli smooth; ventral annuli with rounded microtubercles, setae h1 absent. Female genitalia coverflap with two rows of ridges
