This species is closely related to /. bhotanensis, Cam.; that 

 mav be known, inter alia, by the absence of a middle keel 

 on the third se_2;ment, by the mnch weaker keel on the first, 

 and by the keel on the second being triangularly dilated at 

 the base. 



Also to I. pauperafuSj Cam. ; that has the keel on the 

 second abdominal segment dilated at the base, and it does 

 not reach to the apex of the segment ; the space on either 

 side of it is obliquely striated, not perfectly smooth as in the 

 present species.
