Canestrini (1891, in: Atti 1st. Veneto, ser. 7 ft 2 p. 718) and Banks (1895. in: Tr. 

 Amer. ent. Soc, V. 22 p. 2) state, that this genus is composed of immature creatures, 

 but this is an error.

) As the name Michaelia was preoccupied I have renamed Haller's genus in 

 honor of Dr. H. Lohmann. Berlese's gen. Michaelia (Trombidiidae). in: A. M. S.. fasc. 16 

 nr. 6 & fasc. 57 nr. 8. was published 29. December 1884. A.D.Michael.
