130 Acarology 



median plate is in reality a sclerotized portion of the vaginal wall. The 

 metasternal plates are fused with the sternal plate if these plates are 

 present. Lateral shields are present or if absent they are secondarily 

 reduced. The male genital opening is in the center of the sternal plate 

 that is closed by a plate attached at its anterior margins. 



The Fedrizziina can be conveniently separated into seven families 

 as indicated by the following key that is a modification of one pub- 

 lished by Tragardh 1946. 



Key to the Fedrizziina 



1. Sternal and metasternal plates sclerotized 2 



Sternal and metasternal plates not sclerotized in female; their posi- 

 tions indicated only by locations of sternal and metasternal setae 



Parantennulidae 



2. Lateral plates separate 3 



Lateral plates fused along midline; median plate reduced 



Syngynaspidae 



3. Median plate not fused to sternal plate 4 

 Median plate fused to sternal plate Cercomegistidae 



4. Lateral plates completely sclerotized 5 



Lateral plates sclerotized only along median margin 



Antennophoridae 



5. Lateral plates triangular Paramegistidae 

 Lateral plates linear Fedrizziidae 



Parantennulidae Willmann, 1940

Diagnosis: The dorsal plate is undivided, and the sternal and meta- 

 sternal plates of the females are lacking. Tarsus i has no ambulacral 

 apparatus, while tarsi ii, in, and iv have large caruncles and tiny claws. 

 Chelicerae are chelate.
