 (Bs) conical, about twice as long as basal width, clothed with numerous setae 

 (longer ventrally and apically); two dense patches of moderately long setae 

 present on inner surface, one patch arising near base of subapical lobe and the 

 other just posterior to subapical lobe. Subapical lobe (S-L) arising near 

 middle of basistyle, stout, thumb-like, a little more than twice as long as wide, 

 bearing two long and one short, slightly flattened rods on apex (the longest 

 rod shorter than the subapical lobe) and a row of several flattened setae on
