This is rather a remarkable species. It must be provisionally 

 placed in CJielidurella, but it has no real resemblance to C. acatitJw- 

 pyyia, the type of that genus. The whole body is spindle-shaped, 

 being gently broadened from the pronotum to the first or second 

 abdominal segment, where the maximum width is attained, and then 

 gradually narrowed to the apex.
