the anterior margin. Grooves for the reception of the anterior, middle and hind tarsae present 
on the propleurae, metasternum and first visible abdominal sternite. Scutellum simple, 
without carina. Second, third and fourth tarsal segments with small ventral lobes. 
HISTORY OF THE GENUS. Cryptotarsus was established for a single species from 
Chile with grooves on the propleurae for the reception of the anterior tarsi. 
Hexaulacus was also established for a single Chilean species with grooves for the 
reception of the anterior, middle and hind tarsi on the propleurae, metasternum 
and first visible abdominal segment. Calvert (1889: 18) suggested that C. ater 
Philippi and H. rveedi Candéze were conspecific but Fleutiaux was of the opinion 
that this could not be the case as Philippi mentions only one pair of tarsal grooves. 
Golbach (1970) : 306) examined the type of C. ater and found that six tarsal grooves 
are present as in veedi. As Golbach suggests, the position of the middle and hind 
legs probably prevented Philippi from seeing the tarsal grooves on the metasternum 
and abdomen.
