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 Bibloplectus, the basal joint strongly carinate, the 

 much shorter body, and the decidedly cordate prothorax.
