So far as what may be regarded as specific features are 

 concerned, this species differs apparently from the two known 

 species of Diplothele in the uniform dark colouring of the 

 abdomen, the greater height and convexity of the carapace, 

 the shortness and straightness of the teeth of the rastellum, 

 the larger number and irregular arrangement of the maxillary 

 cusps, and especially in the spine-armature of the third and 

 fourth legs.
