expanded and covering the cylindrical scale layer, Anellus, a trans- 

 verse membrane, with triangular pointed and porrect anellus lobes. 

 Saccus moderate; top, a transverse round disc, Aedeagus extremely 

 long and slender, cornuti several long ridges of fine bristles. 



Female genitalia: Ovipositor weak, a single, collar-like, obtusely 

 pointed dorsal lobe, with long and slender postapophyses. Sterigma, 

 a pair of bandlike sclerites moderately dilated towards middle, lamella 

 antevaginalis apparently represented by a small median oval sclerite. 

 Anapophyses slender, shorter than postapophyses. Between sterigma 

 and ovipositor there is an additional division, segment-like and with 

 a pair of extra apophyses-like thin rods. Colliculum, a dark slender 

 cylinder. Ductus bursae extremely long and narrow, spiraled, its 

 lower portion and wall of corpus bursae finely punctulate or dentic- 

 ulate, Signa two, a group of sclerotized parietal folds and a huge 

 flat hook with regularly serrate edge.
