the abdominal segments and the much shorter body differentiate it 

 from Asymoplectus, and the distinctive characters which separate it 

 from Bibloplectus, which has also the dorsal part of the abdominal 

 segment subequal, are the much smaller sixth ventral segment, and 

 in the male the seventh one which has no operculcum, a strong 

 characteristic of Bihloplectus, the basal joint strongly carinate, the 

 much shorter body, and the decidedly cordate prothorax.
