Cameron differentiates this species from all the other forms 

 ascribed by him to the genus Pimpla in his 1899 paper, by its 

 having the " body and legs entirely black ; " but in his diagnosis 

 we find '' tibiis tarsisque anticis flavotestaceis," and later ^also 

 " the middle knees are testaceous."
