1884. Berlese likes exaggeration ! »Corpus setis longissimis 

 corpore magis quam duplo longioribus." He moreover mentions 

 the villous tarsi, calls the copulation-tube »oviductus", draws 

 the foremost pair of dorsal hairs rightly, close together, but 

 delineates the greater part of the hairs a good deal too long. 

 His figures 3 and 4 (copulation tubes) are said to be drawn after 

 Michael. I atn not aware of Michael haviug published something 

 about Glycyphagus before the year 1884, but ifso, these copulation 

 tubes do not belong to Gl. cadaveram, as Michael seems never 

 to have observed this species. 



1888. Canestrini. I Tiroglifidi. Only a diagnosis, in which 

 »tarso pedum (prirni et secundi paris) clava sensoria destituto" 

 is contrary to truth. Nothing of the villous tarsi. 



1888. Michael's mite. Glyc. michaeli Oudms., vide below p. 332. 



1888. Canestrini. Prospetto. A good description. He mentions 

 the villous tarsi; however he has not observed the olfactoric hair 

 on the base of the tarsus. For the first time here is question of 

 the texture of the skin »finamente zigrinata". As to his drawings, 

 they are incorrect in many respects, e. g. the foremost pair of 

 dorsal hairs is drawn far from each other, whilst their bases are 

 touching each other. 



1899. Canestrini und Kramer. A bad diagnosis. So they say: 

 (Haare) »den Körper an Lange nicht Uebertreffend" and »am 

 drittletzten Glied des 1. HB. mit breiten Ranclfiedern." This 

 sense is absolutely incomprehensible. Possibly they have meant 

 >mit breiter Schuppe". If so, their »spinipes" is michaeli Oudms., 

 see below, p. 332. 



1901. Michael. Glycyphagus spinipes = Gl. michaeli Oudms. 

 see below, p. 332. 



1903. Oudemans mentions his discovery that the so-called vil- 

 lous tarsi are in reality smooth, but ventrally provided with a 

 long scale, attached at the base of the tarsus; this scale is bare 

 on the side which is turned towards the tarsus and hairy on the 

 opposite side.
