Diagnosis. Most closely related to and likely to be confused with B. bituberculatus . Males are separated from B. bituberculatus by the rounded MA, broad based E and tapering C ( Fig 18 A). Females are separated by the shape of the AH, which is broader in B. cinerascens and the tapering ET; in B. bituberculatus the ET is stouter ( Figs 18 D, 20D).

Description. Male palps as in Figs 18 A–C. Epigynum as in Figs 18 D, E. Described in detail in Barrion and Litsinger (1995).

Distribution. China, Indonesia, Malaysia, New Guinea, Philippines.
