Subfamily V. COLOBATHRISTINtE. 



This small subfamily differs from the other Lygseidae in having 

 the abdomen contracted at base and the second and third segments 

 very long. 



The subfamily Colobathristinae contains only three genera, 

 according to our present knowledge : two confined to the Oriental 

 (Indo-Malayan) Eegion, the other being both Oriental and also 

 Neotropical in distribution.
