 sinuate and fringed with long hairs within, the anterior pair (and sometimes the 

 intermediate pair also) with a sharp subapical tooth on the inner edge, the anterior 

 pair distinctly produced at the outer apical angle; the third tarsal joint small. 

 I have seen numerous specimens of 8. memnonius (including the type) and one of

 by three examples from each locality, one of them measuring only 6 J mm.
