It is not certain that my identification of this species is correct 
but it is highly probable.

Ann. Soc. Ent. Belg. xii. 1898, p. 20(¢, 9). 
Type ¢, gynetype 2? ,incoll. H. Simon. Total length’ ¢ 9,7mm. 
One would suspect, from the descriptions, that this species is 
congeneric with H. palustris, the males having the mandibles 
convex and carinate on their outer apical margin.
